Answer:

I think A sorry if its wrong

Explanation:

Answer 2

All plants and animals have mechanisms or ways to transport nutrients within the cell. The correct option is a.

What is the transport of nutrients?

Water is a nutrient that aids in the movement of substances through our bodies and the control of body temperature. The growth, development, and maintenance of the tissues and cells in our bodies depend on minerals like calcium and iron.

While the Phloem carries organic nutrients in plants, the Xylem carries water and minerals.

Animals' intestines absorb the water we drink, which is then transported throughout the body as bodily fluids like blood. These carry out a variety of tasks that keep us alive. They provide the cells with oxygen and nutrition and remove waste products, which are eventually expelled through urination.

Therefore, the correct option is a. transport nutrients within the cell

B. Ionic
C. Covalent
D. Electrostatic

Answers

Final answer:

A molecule of N2 features a triple covalent bond, where the nitrogen atoms share three pairs of electrons equally, forming one of the strongest covalent bonds.

Explanation:

The bond between the atoms in a molecule of N2 is a covalent bond. This is because the two nitrogen atoms have the same electronegativity and thus share electrons almost equally between them, creating a stable bond. In the case of diatomic nitrogen (N2), the nitrogen atoms form a triple bond, which is one of the strongest covalent bonds, involving the sharing of three pairs of electrons.

A solution with pH of 9.50 has a pOH of?

Answers

Answer:4.5

Explanation:

14-9.5

pH can be defined as the degree of how acidic or basic a given solution is. pOH can be defined as the concentration of OH- ions in a given solution.

A solution with a pH of 9.50 has a pOH of 4.5

The formula to solve the above question is given as:

pH + pOH = 14

From the question,

pH = 9.50

Hence, 9.5 + pOH = 14

Subtract 9.5 from both sides

9.5 - 9.5  + pOH = 14 - 9.5

pOH =  14 - 9.5

pOH = 4.5

Therefore, a solution with a pH of 9.50 has a pOH of 4.5

What is Bronsted-Lowry acid ?

The Bronsted-Lowry hypothesis (Proton theory of acid and base) is an acid-base reaction theory proposed in 1923 by a chemist Johannes Nicolaus Bronsted and English chemist Thomas Martin Lowry. According to the hypothesis, acid and base react with each other and generate conjugate bases and conjugated acids through proton exchange.

The Bronsted-Lowry theory is an enhanced version of the Arrhenius acid-base theory.

According to the Arrhenius hypothesis, acid increases the concentration of H+ ions in aqueous solution whereas base increases the concentration of OH- ions. The Arrhenius theory has a restriction in that it only detects the interaction of an acid and a base in an aqueous medium.

Hence option B is correct.

A solution contains 90 grams of a salt dissolved in 100 grams of water at 40ºC. The solution could be an unsaturated solution of...
A) KCl
B) KNO3
C) NaCl
D) NaNO3

Answers

Answer:

D) NaNO₃

Explanation:

In this case, to know this, we need to watch the solubility curve of each compound to know which one is saturated or unsaturated in this case.

As you can see in the curve attached, let's analize first what is an unsaturated solution.

An unsaturated solution is a solution where the quantity of solvent is in excess and the solute is completely dissolved in solution leaving no remains. This depends of the temperature of course. The solubility of one compound vary with the increase or decrease of temperature.

As you can see in the graph attached, what happens to the KCl?, we can see that a 40 °C, you just need around g of solute to be dissolved, and be saturated so, this is not the correct choice.

If you watch NaCl, has a similar behavior. You just need about 35 g of solute to be saturated.

Finally the KNO₃ just need 60 g of solute to be dissolved in solution, completely.

In the case of NaNO₃ we can see that at 40 °C it's not touching the curve, so we can assume that this is an unsaturated solution and it would be the correct choice.

Final answer:

An unsaturated solution is one in which more solute can still be dissolved in the solvent. In this case, the solution contains 90 grams of the salt dissolved in 100 grams of water. However, without knowing the solubility of each salt at 40ºC, we cannot determine which salt could form an unsaturated solution at that temperature.

Explanation:

An unsaturated solution is one in which more solute can still be dissolved in the solvent. In this case, the solution contains 90 grams of the salt dissolved in 100 grams of water. If the solution were saturated, it would contain the maximum amount of solute that can be dissolved at that temperature. Since the solution has less solute than the maximum solubility, it is an unsaturated solution.

To determine which salt it could be, we need to compare the solubility of each salt at 40ºC. Unfortunately, the information provided does not include the solubility data for the salts. Therefore, we cannot determine which salt could form an unsaturated solution at 40ºC based solely on the information given.

A gas occupies the volume of 215ml at 15C and 86.4kPa?
What is the volume of the gas in STP?
Steps?

Answers

Answer:

About 0.1738 liters

Explanation:

Using the formula PV=nRT, where p represents pressure in atmospheres, v represents volume in liters, n represents the number of moles of ideal gas, R represents the ideal gas constant, and T represents the temperature in kelvin, you can solve this problem. But first, you need to convert to the proper units. 215ml=0.215L, 86.4kPa is about 0.8527 atmospheres, and 15C is 288K. Plugging this into the equation, you get:

[tex]0.8527\cdot 0.215=n \cdot 0.0821 \cdot 288\\n\approx 7.754 \cdot 10^{-3}[/tex]

Now that you know the number of moles of gas, you can plug back into the equation with STP conditions:

[tex]1V=7.754 \cdot 10^{-3} \cdot 0.0821 \cdot 273\\V\approx 0.1738L[/tex]

Hope this helps!

Please show your work - thank you! :)

Answers

Answer:

A. 4500 mL

Explanation:

We need to use a version of the combined gas law, which states:

[tex]\frac{V_1}{n_1T_1}= \frac{V_2}{n_2T_2}[/tex] , where T represents temperature, V volume, and n moles

First, look at the initial values of n, V, and T:

- n: we have 10.0 grams of hydrogen, which we need to convert to moles. So: [tex]10.0g*\frac{1 mol}{2.02 g} =4.95molH_2[/tex]

- V: we have a volume of 5.0 L

- T: our temperature right now is 28.0°C, but we need it in Kelvins, so add 273: 28.0 + 273 = 301 K

Now look at the final values:

- n: our final number of grams is 8.5 grams of hydrogen, so we need to convert this to moles.

[tex]8.5g*\frac{1 mol}{2.02 g} =4.2molH_2[/tex]

- V: this is what we want to find

- T: our final temperature is 44.0°C; to convert it to Kelvins, add 273.

44.0 + 273 = 317 K

Put this altogether:

[tex]\frac{V_1}{n_1T_1}= \frac{V_2}{n_2T_2}[/tex]

[tex]\frac{5.0}{4.95*301}= \frac{V_2}{4.2*317}[/tex]

Multiply both sides by (4.2 * 317):

[tex]V_2[/tex] ≈ 4.5 L

However, the problem wants millilitres, so simply multiply 4.5 by 1000:

4.5 * 1000 = 4500

The answer is thus A.

Option (A) 4500 ml

Thus, heat of reaction is -65kJ

Calculate the concentration of hydroxide ions (OH-) in a solution with a pOH of 2.52?

Answers

Answer:

The concentration of hydroxide ions is 3.02*10⁻³ M

Explanation:

The pOH (or OH potential) is a measure of the basicity or alkalinity of a contamination and is defined as the negative logarithm of the activity of the hydroxide ions. That is, the concentration of OH- ions:

pOH= -log [OH-]

The pOH has a value between 0 and 14 in aqueous solution, the solutions with pOH being greater than 7 being acidic, and those with pOH less than 7 being basic.

If pOH= 2.52 then

2.52= -log [OH-]

[OH-]= 3.02*10⁻³ M

The concentration of hydroxide ions is 3.02*10⁻³ M

Answers

Answer:

90%

Explanation:

Percentage yield = ?

Theoretical yield = 50g

Actual yield = 45g

To calculate the percentage yield of a compound, we'll have to use the formula of percentage yield which is the ratio between the actual yield to theoretical multiplied by 100

Percentage yield = (actual yield / theoretical yield) × 100

Percentage yield = (45 / 50) × 100

Percentage yield = 0.9 × 100

Percentage yield = 90%

The percentage yield of the substance is 90%

How many mL of 2.0 M KOH are necessary to neutralize 50 mL of 1 M HCl?

Answers

Answer:

25mL

Explanation:

Please see the step-by-step solution in the picture attached below.

Hope this can help you. Have a nice day!

25 mL of 2.0 M KOH are required to neutralize 50 mL of 1 M HCl due to the 1:1 reaction ratio and molarity calculations.

To determine how many milliliters of 2.0 M KOH are necessary to neutralize 50 mL of 1 M HCl, we first write the balanced chemical equation:

1. KOH(aq) + HCl(aq) → KCl(aq) + H2O(l)

Since the reaction ratio of KOH to HCl is 1:1, we can calculate the moles of HCl and thus the moles of KOH needed for neutralization:

Calculate moles of HCl: 50 mL × 1 M = 50 mmol of HCl

Calculate moles of KOH needed: 50 mmol of HCl × (1 mol KOH / 1 mol HCl) = 50 mmol of KOH

Convert moles of KOH to volume: 50 mmol / 2.0 M = 25 mL of KOH

Therefore, 25 mL of 2.0 M KOH are required to neutralize 50 mL of 1 M HCl.

Explain why copper metal reacts with nitric acid but does not react with hydrochloric acid​

Answers

Copper is an unreactive metal and doesn't react in normal circumstances with dilute acids. However, it does react with nitric acid. ... Nitric acid is an oxidizing agent and the reaction is not the usual acid + metal reaction. The products are oxides of nitrogen instead of hydrogen

Hope it helps!! :)
Final answer:

Copper metal reacts with nitric acid but does not react with hydrochloric acid due to the difference in reactivity between the two acids. Nitric acid is a strong oxidizing agent, while hydrochloric acid is a weaker acid.

Explanation:

Copper metal reacts with nitric acid but does not react with hydrochloric acid due to the difference in reactivity between the two acids. Nitric acid is a strong oxidizing agent, meaning it readily donates oxygen atoms or accepts electrons from other substances. Copper is less reactive compared to hydrogen, so when it reacts with nitric acid, it displaces hydrogen from the acid, resulting in the formation of copper (II) nitrate, nitrogen dioxide, and water.

On the other hand, hydrochloric acid is a weaker acid and does not have strong oxidizing properties like nitric acid. Therefore, copper does not react with hydrochloric acid. Instead, metals like zinc or magnesium, which are more reactive, can react with hydrochloric acid to form hydrogen gas and the corresponding metal chloride.

How much heat must be removed from 15.5 g of water at 90.0°C to cool it to 43.2°C?

Answers

Answer:

Heat, Q = 3035.073 J

Explanation:

It is given that,

Mass of water, m = 15.5 g

Initial temperature, [tex]T_i=90^{\circ} C[/tex]

If a variable increases by a fixed amount over an equal amount of time, it will grow linearly. Real-world problems frequently show nonlinear progression.

The exponential function and the power function are two other functions that can model data. If a fixed number higher than 1 is multiplied by a variable in equal intervals, the variable will expand exponentially.  

A power regression is one in which the explanatory variable is increased to a power and the response variable is proportionate to it.

We can build the models similarly because exponents are used in both the exponential form and the power form. The log from both sides is first taken.
