Definition of Terms

Lack of water availability is a natural situation that occurs where and when water becomes scarce and not readily available for use.

Possible Threats

Most of the threats caused b water lack of water availability are caused by human activities both necessary and unnecessary while others are caused by nature responding to some of those human activities. These threats include pollution, change of landscape, urban growth, deforestation and climate change.

How to reverse these threats

Implementing adequate hydrologically-based water assessment and management processes:

Landscape changes which are inevitable, are of different types and therefore poses different specific impact on the ecosystems directly or on water availability indirectly. The strength of the impacts will vary with a wide range of possible landscape changes depending the settings conditions. For this reason, it is imperative that for certain parts of the world where the threat of water availability is experienced that adequate hydrologically-based water assessment and management processes be implemented.

Developing optimum, scalable and energy efficient plants for desalination:

For man ears desalination has helped solved lack of water availability in certain parts of the world, but these desalination plants are energy-intensive. However, with newer technologies, these plants would require less energy and when utilized would reverse the threats posed by lack of water availability.

Innovative water catchment and harvesting:

Water catchment systems are imperative for areas with lack of water availability in order to store more waters as gotten from other sources where it is readily available, whilst also recycling the waste waters in those areas too.

Better policies and regulations while educating the masses:

Lack of water availability would affect food security and even cause pollution, therefore the government would need to make better policies and regulations guiding the use of water whilst educating the masses on the need to change their water consumption and lifestyles. And this is easily done when the water available is appropriately priced.

Holistic Ecosystem management:

This type of management means taking into account the ecological, economic and cultural goals that affects the country's natural resources, and this approach has to be holistic, logical and practical. Why holistic approach? Simply because each aspect is related to and influenced by the others.

Improved Distribution Infrastructure:

Poor infrastructure poses threats to health and even the nations economy. The infrastructural system in place for waver distribution must be of good quality and constantly checked and maintained.

The above stated approach would reverse lack of water availability in any nation.

The correctly matched pair is :

[tex]NH_{3}[/tex] is Polar

Explanation:

Polarity is decided by net dipole moment . If a molecule has 0 dipole moment then it is non-polar .

If a molecule has some value of dipole moment then it is polar.Unit of dipole moment is Debye(D)

[tex]{dipole moment = charge \times distance}[/tex]

In chemical value of dipole is based on two factors :

1. There should be heteroatomic bond in a given compound..e.g H-Cl , C-N

(not C-C, N-N)

2. The molecule should be unsymmetrical in shape.

note : even if all bonds are heteroatomic but shape is symmetrical , then also dipole moment can be zero

CORRECT MATCHES

[tex]H_{2}O[/tex] : Polar

It has net dipole moment of 1.85 D because its shape is bent (unsymmetrical) and all bonds are heteroatomic.

[tex]CH_{4}[/tex] :Non-Polar

All bonds are heteroatomic(C-H) but shape is symmetrical(tetrahedral), so net dipole is zero

[tex]CO_{2}[/tex] : Non -Polar

All bonds are heteroatomic(C=O) but shape is symmetrical(linear), so net dipole is zero

NH3 is correctly identified as polar due to its trigonal pyramidal shape causing an unequal electron distribution. In contrast, H2O is polar (not non-polar), CH4 is non-polar (not polar), and CO2 is non-polar (not polar), illustrating the importance of geometric arrangement in determining molecular polarity.

The question involves understanding molecular polarity, a fundamental concept in chemistry. The correct pairing from the options provided is NH3: polar. Let's delve into the rationale behind this answer and correct the misconceptions concerning the other molecules listed.

To summarize, molecular polarity is determined not only by the presence of polar bonds but also by the molecule's geometry. In this context, NH3 is the correct answer since it is polar due to its geometry leading to an unequal distribution of electron density.

Explanation:

you must be know the formula of potassium permaganate is KMnO₄

now you have already in question 2 things ,

1. the molarity of solution = 0.532 M

2. the mass of KMnO₄ = 2.99 g

the molarity law is  M = moles of solute  / volume (L)

so use this equation to calculate the volume in liter and convert the result to milliliter.

( if the mass unit is gram (g) = volume must be litter (L) and if the mass unit is milligram = volume must be milliliter (ml) )

** first you must use this equation to calculate how many moles do you have in KMnO₄

number of moles = mass (g) / molecular weight "MW" (g/mole )  

now you have 2.99 g ( Mentioned in Question )

and you can calculate MW if you now the Chemical formula

so we have KMnO₄  

Mw for KMnO₄  = 39 + 55 + 4x16 = 158 g/mole

**( K=39 , Mn=55 , O= 16 )

so number of moles = 2.99 / 158 = 0.018 = 0.02 moles

and if you go back to the molarity law : 

Molarity = moles of solute  / volume (L)

so  0.532 = 0.02  / volume (L)

Volume (L) = 0.532 x 0.02 = 0.01064 L

convert to ml =  0.01064 x 1000 = 10.64 ml

Explanation:

[tex]Li_3PO_4[/tex] is an ionic crystal rather than a molecule. An ionic crystal dissolved in water dissociates into its cations and anions.

Lithium phosphate consists of two ions. Firstly, the metallic component, lithium, is a positively charged ion in this salt, also known as a cation.

The remaining part, phosphate, is an anion. When lithium phosphate is dissolved in water, the following process takes place:

[tex]Li_3PO_4 (aq)\rightarrow 3 Li^+ (aq) + PO_4^{3-} (aq)[/tex]

Notice that for 1 formula unit of lithium phosphate, a total of 3 units of lithium cations and 1 unit of phosphate anions are produced.

The correct answer is 4 ions will be produced when the Li3PO4 molecule dissolves in a solvent.

Lithium phosphate (Li3PO4) is an ionic compound composed of lithium (Li) cations and phosphate (PO4) anions. When Li3PO4 dissolves in a solvent, it dissociates into its constituent ions.

The lithium ion (Li+) has a charge of +1, and there are three lithium atoms in the Li3PO4 molecule. Therefore, when dissolved, these will produce three lithium ions (3 Li+).

The phosphate ion (PO4^3-) has a charge of -3. Since there is only one phosphate group in the molecule, it will dissociate into one phosphate ion (1 PO4^3-).

To find the total number of ions produced, we add the number of lithium ions to the number of phosphate ions:

Total number of ions = Number of lithium ions + Number of phosphate ions

Total number of ions = 3 + 1

Total number of ions = 4

Therefore, 4 ions in total are produced when Li3PO4 dissolves in a solvent: 3 lithium ions (Li+) and 1 phosphate ion (PO4^3-).

Answer:

Going up the group

Explanation:

In any main group, the first ionization energy increases going up the group, while going down, it decreases.

The reason for that lies in understanding the fundamentals of the Coulombic attraction force. Going down the group, atomic radius increases. When atomic radius increases, the distance between a nucleus and valence electrons increases. According to the Coulomb's equation, force is inversely proportional to the square of the distance. This implies that the greater the radius, the lower the attraction between a nucleus and valence electrons.

Now, the lower the attraction, the lower the energy required to remove the electron.

That said, the first ionization energy increases up the group, as atomic radius decreases.

The ionic compound formed from lithium ions (Li+) and iodide ions (I-) is Lithium Iodide (LiI). This is an example of an ionic compound, which typically forms when a metal reacts with a nonmetal.

The ionic compound that consists of lithium ions (Li+) and iodide ions (I-) is called Lithium Iodide, denoted as LiI. In this compound, lithium is a metal and iodide is a nonmetal, making the compound ionic. The lithium atom donates an electron, forming a Li+ ion, and the iodine atom accepts an electron, forming an I- ion. Subsequently, the Li+ and I- ions attract each other due to their opposite charges, forming an ionic bond and yielding the ionic compound Lithium Iodide.

Lithium Iodide is just one example of an ionic compound. Ionic compounds typically form when a metal reacts with a nonmetal. Other examples can include sodium chloride (NaCl), and calcium chloride (CaCl2), where a transfer of electrons occurs, producing ions.

Lithium iodide is the name of the ionic compound made up of lithium ions (Li+) and iodide ions (I-). The compound's formula is LiI. The name follows the standard naming convention for ionic compounds.

An ionic compound consisting of lithium ions (Li⁺) and iodide ions (I⁻) is known as lithium iodide. The metal cation name—in this case, lithium—should come first when naming ionic compounds. This is succeeded by the non-metal anion's name, iodine, with a modified '-ide' at the end. Iodine is therefore substituted with iodide.

This naming scheme makes the compound's ionic nature easier to identify. Iodide ions have a 1 charge, signifying that they have gained one electron, whereas lithium ions have a 1+ charge, signifying that they have lost one electron. With the help of their mutual attraction, these opposing charges balance one another out to create a neutral compound with the chemical formula LiI.

As a result, one lithium ion and one iodide ion form the compound lithium iodide, illustrating the basic ideas behind the synthesis and nomenclature of ionic compounds.

Answer:

The answer is (C) the kinetic energy of particles in a system.

Final answer:

Thermal energy is the kinetic energy of the particles in a system, associated with their random motion. It increases with temperature, highlighting the link between kinetic energy and temperature as a measure of this energy's concentration.

Explanation:

Thermal energy is essentially the kinetic energy associated with the random motion of atoms and molecules in a system. It represents a form of internal energy that is dependent on temperature, increasing as the temperature of the system rises. This form of energy is related to the movement—whether through vibration, rotation, or translational motion—of the particles within a system. It's important to differentiate between thermal energy and temperature; while thermal energy refers to the kinetic energy of the particles, temperature is a measure that represents the average kinetic energy of those particles.

Considering the options provided in the question, thermal energy can be accurately described as the kinetic energy of particles in a system. Notably, thermal energy is a key component of a system's internal energy but is distinct from potential energy, which is another component of internal energy. Temperature measurement, on the other hand, quantifies the concentration of this kinetic energy within the system, providing a direct proportional relationship between temperature and thermal energy at the molecular level.

Answer:

The law of definite proportions

Explanation:

The law of definite proportions states that atoms combine in a molecule in a specific molar ratio or specific stoichiometry. For example, it's proved that regardless of the quantity we take, two hydrogen atoms always combine with one oxygen atom to form a water molecule.

Similarly, ionic substances follow the same pattern. Since the net charge of ionic salts should be equal to 0 and each element has a definite number of valence electrons in its shell all the time, the ions combine in a way, so that cations balance the charge of anions.

Essentially, the law of definite proportions is applicable and will be applicable in the future, since we know that each element has a fixed number of valence electrons in its ground state.

Answer:

The correct functions of the cell membrane are:

Explanation:

The cell membrane is known to be the gatekeeper of a cell. This is because it selectively regulates which materials to let enter into a cell and which materials need to be exited from the cell. Gases like oxygen and carbon dioxide can easily pass through the cell membrane by diffusion. The cell membrane stops the entry of any kind of harmful component into the cell hence, protecting the cell.

The cell membrane is a vital component for the cell's survival. It lets in oxygen and carbon dioxide, stops harmful substances from coming in, and acts as a barrier or gatekeeper; however, it doesn't prevent harmful substances from exiting the cell.

The cell membrane, also known as the plasma membrane, has several vital functions in maintaining the life and health of a cell. This includes allowing useful substances like oxygen and carbon dioxide to enter and exit, acting as a protective barrier to prevent harmful chemicals from entering the cell and allowing certain substances to exit, hence acting like a 'gatekeeper'. Therefore, the correct answers are 'allows oxygen to enter', 'allows carbon dioxide to enter', 'stops harmful chemicals from entering' and 'acts like a gatekeeper'. It does not, however, 'stop harmful chemicals from exiting', as the membrane cannot differentiate between harmful or beneficial when it comes to exiting.

Answer:

 121.76 °C

Explanation:

Data Given:

Boiling point of water = 100.0°C

Kb (boiling point constant = 0.512°C/m

Concentration of the Mg₃(PO₄)₂ = 8.5 m

Solution:

Formula Used to find out boiling point

               ΔTb = m.Kb.i . . . . . . (1)

where

ΔTb = boiling point elevation

m = concentration of solution

kb = molal boiling point elevation constant

i = Van't Hoff factor

Van't Hoff factor : It is the number of ions of ionic compound in the solution produced by it when it dissolve in solvent.

Van't Hoff factor for Mg₃(PO₄)₂:

Assuming ideal Van't Hoff factor Look for ionization of Mg₃(PO₄)₂ in solution

        Mg₃(PO₄)₂ ------> 3 Mg²⁺ + 2 PO₄³⁻

From above equation it is clear that it give total 5 ions in solution form upon dissolving i.e. 3 Mg²⁺ ions and 2 PO₄³⁻ ions.

So,

Van't Hoff factor = 5

Now

As,

       ΔTb = boiling point of solution - boiling point of water

So,

we can write equation 1 as under

               Tb (Solution) -Tb (water) = m.Kb.i

As we have to find out boiling point so rearrange the above equation

              Tb (Solution)  = (m . Kb . i)+ Tb (water) . . . . . . . (2)

Put values in Equation 2

            Tb (Solution)  = (8.5 m x 0.512°C/m x 5) + 100.0°C

            Tb (Solution)  = 21.76 °C + 100.0°C

            Tb (Solution)  = 121.76°C

so the boiling point of 8.5m Mg₃(PO₄)₂ solution =  121.76 °C

It is defined as : having together the oxidized and reduced forms of a substance taking part in oxidation or reduction half reactions .they are actually conjugate acid base pairs

.we can also define it as : an oxidizing and reducing agent which appear on opposite sides of a half equation constitute the redox couple .Like, given below is the cell in which we consider Zn/Cu redox couple .

Electrochemical cell

• Electrochemical cell is the cell in which chemical energy gets converted to electric energy.  

• In it indirect redox reactions takes place.  

• These reactions are spontaneous that is free energy change for this reaction is negative.

• This cell consists of two half cells.  

• In one half cell , there is a aqueous 1molar Zinc sulphate solution with Zinc rod dipped in it.

• In other half cell, there is a 1 molar aqueous solution of Copper sulphate solution with Copper rod dipped in it.

• These electrodes by means of wire are attached to galvanometer.

•  A U-shaped tube is taken, which is sealed from both the ends with cotton plug.

• In this, the electrolyte that is inert electrolyte is taken like Potassium nitrate, Ammonium nitrate etc. The electrolyte present is in semi-liquid state.

Observations

 With time we see that Zinc rod loses weight, as it has more tendency to loose electrons that is:

 These electrons released by zinc, travel to another beaker by means of wire. In doing so, they cause deflection in galvanometer and produce current. This current travel in the direction opposite to the flow of electrons.

 These electrons move to another half cell, where copper ions gain these electrons that is reduction occur. As a result, copper metal start depositing on electrode.

During a chemical reaction, the reactant molecules' chemical bonds are energetically influenced, resulting in the breaking and subsequent rearrangement to form product molecules with new chemical bonds. The best example of this is the reaction of hydrogen and oxygen to produce water, where the initial molecules' bonds are broken and rearranged to form water molecules.

The details of what actually takes place during a chemical reaction are a little complex, but fundamentally, it involves the breaking and forming of chemical bonds. During a chemical reaction, the molecules of the reactants are influenced energetically so their chemical bonds are broken and they subsequently rearrange to form product molecules with new chemical bonds. Let's take a simple example: the reaction between hydrogen and oxygen to yield water:

A cation is a positively charged ion formed by the loss of electrons, whereas an anion is a negatively charged ion formed by the gain of electrons.

A cation is an ion with a positive charge, which occurs when an atom loses one or more electrons. This loss of electrons means that there are more protons than electrons in the cation. On the other hand, an anion is an ion with a negative charge, formed when an atom gains electrons, resulting in more electrons than protons. The sizes of ions change compared to their parent atoms; a cation is always smaller while an anion is larger.

Ions, including cations and anions, are crucial in the formation of ionic compounds. For example, in the compound NaCl, sodium (Na) becomes a cation (Na+) as it loses an electron, and chlorine (Cl) becomes an anion (Cl-) as it gains that electron, forming a neutral compound based on the simplest whole-number ratio of ions.
