The molar mass of a solid carboxylic acid is determined by titrating a known mass of the acid with a standardized solution of NaOH to a phenolphthalein endpoint. Which errors will lead to a molar mass that is smaller than the actual molar mass? I. Some of the acid is spilled when being transferred into the titration flask. II.The endpoint is recorded when the solution is dark red in color rather than light pink.

The enthalpy of combustion of magnesium in this experiment is approximately -602 kJ/mol, which was determined by dividing the total heat transferred (calculated from the calorimeter's heat capacity and temperature change) by the number of moles of magnesium burnt.

In the experiment described, a small piece of magnesium was burnt in a oxygen bomb calorimeter, leading to a recorded temperature rise in the calorimeter and the water it contains. The enthalpy of combustion of magnesium can be determined from these values by using the equation q = mcΔT, where q is the heat transferred, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature. In this case, the total heat transferred (q) is the heat capacity of the calorimeter and the water times the temperature change, or 5760 J/°C * 0.570 °C = 3283.2 J. The molar enthalpy of combustion can then be calculated by determining the moles of Mg burnt (0.1326 g / 24.305 g/mol = 0.00545 mol) and dividing the heat produced by the moles of Mg burnt (3283.2 J / 0.00545 mol = -602 kJ/mol). Therefore, when rounded to 3 significant figures, the enthalpy of combustion of magnesium is around -602 kJ/mol.

Another way static electricity can build up in an object is induction. Induction is the transfer of electrons from one part of an object to another part, caused by the electric field of another object, without the two objects touching.

the answer is,

C. The water strider will have more difficulty moving its feet because they will be more strongly attracted to the water.

Answer:

the answer is D. edg. 2020

Explanation:

You can solve this by utilizing the ideal gas law, PV=nRT. P is pressure, V is volume, n is the number of moles, R is a constant (depends on the unit of pressure), and T is the temperature (in Kelvins).

500.0mmHg- convert to atm

=0.65789atm (do sig figs last)

25.0 C- convert to K

25.0 +273= 298K

PV=nRT

0.65789atm times 45.0L equals n (the variable) times R (0.08206L atm mol^-1 K^-1) times 298K

Isolate the variable, n and plug into a calculator.

Answer: The moles of gas is 1.21 moles.

Explanation:

To calculate the moles of gas, we use the equation given by ideal gas which follows:

[tex]PV=nRT[/tex]

where,

P = pressure of the gas = 500.0 mmHg  

V = Volume of the gas = 45.0 L

T = Temperature of the gas = [tex]25^oC=[25+273]K=298K[/tex]

R = Gas constant = [tex]62.364\text{ L.mmHg }mol^{-1}K^{-1}[/tex]

n = number of moles of gas = ?

Putting values in above equation, we get:

[tex]500.0mmHg\times 45.0L=n\times 62.3637\text{ L.mmHg }mol^{-1}K^{-1}\times 298K\\\\n=\frac{500.0\times 45.0}{62.364\times 298}=1.21mol[/tex]

Hence, the moles of gas is 1.21 moles.

The lowest layer of Earth's atmosphere is called troposphere.The layer immediately next to troposphere is called Stratosphere. The boundary layer between troposphere and stratosphere is described as tropopause.

Answer:

106.6 °C  

Step-by-step explanation:

The formula for boiling point elevation ΔTb is

ΔTb = iKb·b

where

i     = the van't Hoff i# factor

Kb = the molal boiling point elevation constant

b   = the molal concentration of the solution

=====

Data

  i = 2, because 1 mol of NaCl gives 2 mol of ions in solution.

Kb = 0.51 °C·mol·kg⁻¹

 b = 1.00/0.155

 b = 6.452 mol·kg⁻¹

=====

Calculations

ΔTb = 2 × 0.51 × 6.452

ΔTb = 6.58°C

 Tb = Tb° + ΔTb

 Tb = 100 + 6.58

 Tb = 106.6 °C

Answer:

B. 2.12 L  

Step-by-step explanation:

We know we will need a balanced chemical equation with masses and molar masses, so, let's gather all the information in one place.

M_r:                   32.00

        4NH₃(g) + 7O₂(g) ⟶ 4NO₂ + 6H₂O(g)

m/g:                      5.3

(a) Moles of O₂

Moles of O₂ = 5.3 × 1/32.00

Moles of O₂ =0.166 mol

=====

(b) Moles of NH₃

The molar ratio is 4 mol NH₃= 7 mol O₂.

Moles of NH₃ = 0.166 × 4/7

Moles of NH₃ = 0.0946 mol NH₃

=====

(c) Volume of NH₃ at STP

STP is 1 bar and 0 °C. At STP, the molar volume of a gas is 22.71 L.

Volume of NH₃ = 0.0946 ×22.71/1

Volume of NH₃ = 2.15 L

=====

It looks as if you are using the old (pre-1982) definition of STP.

Under that definition, the molar volume of a gas at STP was 22.41 L.

The volume of NH₃ is then 2.12 L.

So the equation is,

2Cl2(g) + 7O2(g) + 130kcal -> 2Cl2O7(g)

from this , ΔH°rxn=[tex]130kcal.mol^{-1}[/tex]

[tex]mol^{-1}[/tex] is mentioned because it is for per mole of reaction. So for 4. moles of the product [tex]2Cl_{2} O_{7}[/tex] we need 4/2 moles of reaction to be used to calculate associated enthalphy change for the reaction.

Therefore[tex]4/2*130=260 kcal[/tex]

1) Answer is: False.

Balanced chemical reaction: Pb + AlCl₃ → no reaction.

The reactivity series is a series of metals from highest to lowest reactivity. Metal higher in the reactivity series will displace another.

Aluminium (Al) is higher in activity series than lead (Pb).

That means aluminium (Al) is stronger reducing agent than lead and gives electrons easier.

This series are used to summarize information about the reactions of metals with acids or water, double displacement reactions (more reactive metals displace metals with lower reactivity) and the extraction of metals from their ores.

2) Answer is: Na3PO4 + 3KOH → 3NaOH + K3PO4, because K retains the same charge throughout the reaction.

This chemical reaction is double displacement reaction - cations (K⁺ and Na⁺) and anions (PO₄³⁻⁻ and OH⁻) of the two reactants switch places and form two new compounds.

Na₃PO₄ is sodium phosphate.

KOH is potassium hydroxide.

NaOH is sodium hydroxide.

K₃PO₄ is potassium phosphate.

3) Answer is: Zn + H2SO4 → ZnSO4 + H2.

Single replacement is reaction where neutral element metal or nonmetal become an ion as it replaces another ion in a compound.

In this balanced chemical reaction zinc (Zn) replaces hydrogen (H).

Zinc changes oxidation number from 0 to +2 (this is oxidation) and hydrogen change oxidation number from +1 to 0 (reduction).

4) Answer is: A single replacement reaction takes place because sodium is more reactive than hydrogen.

Balanced chemical reaction:

2Na(s) + 2H₂O(l) → 2NaOH(aq) + H₂(g).

Single replacement is reaction where neutral element metal or nonmetal become an ion as it replaces another ion in a compound.

In this balanced chemical reaction sodium (Na) replaces hydrogen (H).

Sodium changes oxidation number from 0 to +1 (oxidation) and hydrogen change oxidation number from +1 to 0 (reduction).

5) Answer is: True.

For example, balanced chemical reaction:

Ca + 2HCl → H₂ + CaCl₂.

Reduction hald reaction: 2H⁺ + 2e⁻→ H₂.

Oxidation half reaction: Ca⁰ → Ca²⁺ + 2e⁻.

In this balanced chemical reaction calcium (Ca) replaces hydrogen (H).

In this chemical reaction, calcium lost two electrons (oxidation, change oxidation number from 0 to +2) and hydrogen gain that two electrons (reduction, change oxidation number from +1 to 0).

6) Answer is: It is a single replacement reaction, and the cations in the two ionic compounds are different.

For example, balanced chemical reaction:  

Ba + MgSO₄ → BaSO₄(s) + Mg.

In this balanced chemical reaction barium (Ba) replaces magnesium (Mg), because barium is higher at activity series.

Sulfate anion (SO₄²⁻) is the same in two ionic compounds, but cations (Mg²⁺ and Ba²⁺) changes.

Single Displacement is reaction where neutral element metal or nonmetal become an ion as it replaces another ion in a compound.

Atomic radius of bromine (Br) is 114 pm.

Atomic radius of oxygen (O) is 73 pm.

Atomic radius of fluorine (F) is 72 pm.

Atomic radius of krypron (Kr) is 112 pm.

The atomic radius of a chemical element is a measure of the size of its atom.

The atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

The atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.

Answer is: the two electrons in the fourth shell.

Atomic number of calcium is 20, it means that it has 20 protons and 20 electrons, so atom of calcium is neutral.  

Electron configuration of calcium atom: ₂₀Ca 1s² 2s² 2p⁶ 3s² 3p⁶ 4s²; calcium has two valence electrons (4s²).  

In reactions it lose those two electrons ang form cation with positive charge 2+.

Atomic number is the number of protons, which is characteristic of a chemical element.

Beryllium, magnesium,calcium and strontium are alkaline earth metals. The elements have very similar properties.

Alkaline earth metals have in common an outer s- electron shell (two electrons).

Final answer:

2.00 g of oxygen is produced ,option B

Explanation:

To determine how many grams of oxygen are produced when 11.5 g of NO2 is formed, we can use the stoichiometry of the balanced chemical equation:

2 Pb(NO3)2(s) = 2 PbO(s) + 4 NO2(g) + O2(g)

From the equation, we see that 4 moles of NO2 are produced alongside 1 mole of O2. First, we find the number of moles of NO2 that 11.5 g corresponds to:

Molar mass of NO2 = 14.01 (N) + (2 *16.00) (O) = 46.01 g/mol

Moles of NO2 = 11.5 g / 46.01 g/mol

Then, we take into account the mole ratio between NO2 and O2, which is 4:1:

Moles of O2 = (Moles of NO2)  times (1 mole O2 / 4 moles NO2)

Finally, we find the mass of O2 produced:

Molar mass of O2 = 2  times 16.00 g/mol = 32.00 g/mol

Mass of O2 = (Moles of O2)  times (32.00 g/mol)

By going through the calculations, we find that the mass of O2 produced is 2.00 g, which corresponds to option (b).

Ionic bond is described as the chemical bond between two oppositely charged ions. In ionic bond the metal loses electron forming a positively charged cation and a non metal which accept the cation to form a negatively charged anion. In ionic bond the atoms are held together by electrostatic force of attraction. In ionic bond the anions and cations are present in the ratio where the total charge of the compound becomes zero. For example, Let us consider NaCl compound. An atom of the sodium has three electrons in its valency shell and the electrons are removed from the outer most shell by applying the energy of 5.14 electron volts. The chlorine atom lacks an electron to attain stable electronic configuration and it accepts the electron from the sodium by releasing 3.62 electron volts of energy which means that it takes only 1.52 electron volts of energy to donate an electron to chlorine when both the atoms are far apart. When these electrons are brought together their electric potential becomes more negative. This means that if the neutral sodium and chlorine atoms are found themselves closer it would be energetically favourable to transfer electrons from sodium to chlorine thus resulting in the formation of the ionic bond.

The ions in an ionic bond are held together by electrostatic attraction between the anions and cations in the compound.

For example, sodium chloride [NaCl] (more commonly known as salt) has positively charged sodium [Na+] ions, or cations, and negatively charged chlorine [Cl-] ions, or anions, holding the compound together.

Thus sodium needs to lose one electron in order to attain noble gas configuration and Oxygen needs to gain two electrons to attain noble gas configuration.

Thus Na will lose one electron to form [tex]Na^+[/tex] and Oxygen gain two electrons to form [tex]O^{2-}[/tex]. In order to form a stable neutral compound, two sodium ions are required.

What are moles?

Thus sodium needs to lose one electron in order to attain noble gas configuration and Oxygen needs to gain two electrons to attain noble gas configuration.

Thus Na will lose one electron to form [tex]Na^+[/tex] and Oxygen gain two electrons to form[tex]O^{-2}[/tex] In order to form a stable neutral compound, two sodium ions are required.

1) Answer is: the oxidation number of manganese in MnO₄⁻ is +7.

Permanganate anion has negative charge 1-.

Oxygen (O) in permanganate anion has oxidation number -2.

x + 4 · (-2) = -1.

x - 8 = -1.

x = +7; oxidation nzmber of manganese.

Oxidation number shows the degree of oxidation of an atom in a chemical compound.

2) Answer is: Zn + Cu2+ → Zn2+ + Cu.

In this chemical reaction, there is transfer of electrons from zinc (Zn) to copper (Cu). Zinc change oxidation number from 0 to +2 (lost electrons) and copper change oxidation number from +2 to 0 (gain electrons).

Oxidation half reaction: Zn⁰ → Zn²⁺ + 2e⁻.

Reduction half reaction: Cu²⁺ + 2e⁻ → Cu⁰.

In other chemical reactions, there is no change of oxidation number of elements.

3) Answer is: Br2 is the oxidizing agent because its oxidation number decreases.

Balanced chemical reaction: 2Al + 3Br₂ → 2AlBr₃.

In this chemical reaction, aluminium change oxidation number from 0 to +3 (lose electrons) and bromine change oxidation number from 0 to -1 (gain electrons, reduced).

Oxidizing agent is a substance that has the ability to oxidize other substances, to cause them to lose electrons.

In oxido-reduction reaction, at least one element lose and one element gain electrons.

4) Answer is: Br2 + 2Cl− → Cl2 + 2Br⁻.

Oxidation is increase of oxidation number.

In this balanced chemical reaction, chlorine change oxidation number from -1 (Cl⁻) to oxidation number 0 (Cl₂).

Oxidation half reaction: 2Cl⁻ → Cl₂⁰ + 2e⁻.

Reduction half reaction: Br₂ + 2e⁻ → 2Br⁻.

In other chemical reactions, chlorine is reduced.

5) Answer is: Observation 1 is a result of copper ions moving into the solution.

The reactivity series is a series of metals from highest to lowest reactivity. Metal higher in the reactivity series will displace another.

Copper (Cu) is higher in activity series than silver (Ag), so copper lose electron and silver gain electrons.

Copper is oxidized (increase of oxidation number) and silver is reduced.

The oxidation number of manganese in MnO4− is +7. A reaction that can power a battery is Zn + Cu2+ → Zn2+ + Cu. Chlorine is oxidized in the reaction 2ClO3− + 12H+ → Cl2 + 6H2O, and observation 1 in an experiment with copper and silver nitrate indicates copper ions moving into the solution.

The oxidation number of manganese in MnO4− is +7. In this compound, oxygen has a typical oxidation state of -2, and because the compound has an overall charge of -1, the oxidation number of manganese can be calculated using the equation: Mn + 4(×-2) = -1, which gives Mn a oxidation state of +7.

The reaction that could be used to power a battery is Zn + Cu2+ → Zn2+ + Cu. In this redox reaction, zinc is oxidized, going from Zn to Zn2+, and copper is reduced, going from Cu2+ to Cu, allowing for the transfer of electrons necessary to generate electric current.

The oxidizing agent in the reaction 2Al + 3Br2 → 2AlBr3 is Br2, because it is reduced, with its oxidation number decreasing from 0 in Br2 to -1 in AlBr3.

Chlorine (Cl) is oxidized in the reaction 2ClO3− + 12H+ → Cl2 + 6H2O. Here, the chlorine goes from an oxidation state of +5 in ClO3− to 0 in Cl2.

The correct explanation for one of the observations in the experiment with the silver nitrate solution and the copper strip is that Observation 1 is a result of copper ions moving into the solution. When the copper strip is placed in the silver nitrate solution, it undergoes oxidation, and Cu atoms lose electrons to form Cu2+ ions, which then cause the solution to turn blue.

Answer:

This reaction is exothermic because the system shifted to the right on cooling.  

Step-by-step explanation:

 2NO₂   ⇌   N₂O₄

brown    colourless

According to Le Châtelier's Principle, when a stress is applied to a system at equilibrium, the system will respond in a way that tends to relieve the stress.

You applied a stress by cooling the system (removing heat). The system responded by moving in a direction that created more heat.

The mixture became lighter brown on cooling, so the position of equilibrium must have shifted to the right to generate the heat.

The reaction is exothermic.

When the light brown color equilibrium mixture was moved from room temperature to a lower temperature, the mixture turned lighter brown in color shows this reaction is exothermic because the system shifted to the right on cooling.

According the the equilibrium law, if any external element is added in the equilibrium state, ten the whole reaction will shifts to that side which reduces the effect of that additional element.

Given chemical reaction is:

2NO₂(g) ⇌ N₂O₄(g)

Where NO₂ shows brown color and N₂O₄ is colorless gas. If we notice a light brown color of the mixture when we moved from room temperature to a lower temperature then the reaction will shifts to the right side and will show exothermic behavior to overcome the external effect.

Hence, option (d) is correct.
