Answer:

Check Explanation.

Explanation:

When we are talking about the reservoirs of carbon we mean the places where carbon are been stored. So, we will be considering the places where carbon can be stored in our planet. Remember that carbon is the 6th element in the periodic table or chart.

Within these Reservoirs, the carbon moves from one to another and that is called Carbon cycle. The reservoirs of carbon can be in the atmosphere, the lithosphere and in the biosphere.

(1). Carbon can be stored in the atmosphere as Carbondioxide,CO2.

(2). Carbon can be found on lithosphere in sedimentary rock such as limestone. Also, as components in fossil fuels.

(3). Carbon can be found in the biosphere as soil carbon.

Which of the following functional groups acts most like an acid in water? A) carboxyl B) amino C) carbonyl D) hydroxyl.

Anestetic [448]

Answer : A - carboxyl group.

The carbon in the carboxyl group is bonded to a hydroxyl group and also it is double bonded to an oxygen group.

The carboxyl group when it is dissolved in a solution donates it's hydrogen ion(H+ ion). When it is dissolved in water, the carboxyl group loses its H+ ion to form negatively charged ion.

RCOOH + H2O⇄RCOO- + H3O+

Thus the carboxyl group act as an acid when dissolved in water.

At the Henry's Law constant for carbon dioxide gas in water is . Calculate the mass in grams of gas that can be dissolved in of

Dvinal [7]

The question is incomplete, here is the complete question:

At 25°C Henry's Law constant for carbon dioxide gas in water is 0.031 M/atm . Calculate the mass in grams of gas that can be dissolved in 425. mL of water at 25°C and at a partial pressure of 2.92 atm. Round your answer to 2 significant digits.

Answer: The mass of carbon dioxide that can be dissolved is 1.7 grams

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

$C_{CO_2}=K_H\times p_{CO_2}$

where,

$K_H$ = Henry's constant = $0.031M/atm$

$C_{CO_2}$ = molar solubility of carbon dioxide gas

$p_{CO_2}$ = partial pressure of carbon dioxide gas = 2.92 atm

Putting values in above equation, we get:

$C_{CO_2}=0.031M/atm\times 2.92 atm\\\\C_{CO_2}=0.0905M$

To calculate the mass of solute, we use the equation used to calculate the molarity of solution:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

Given mass of carbon dioxide = ? g

Molar mass of carbon dioxide = 44 g/mol

Molarity of solution = $0.0905mol/L$

Volume of solution = 425 mL

Putting values in above equation, we get:

$0.0905mol/L=\frac{\text{Mass of carbon dioxide}\times 1000}{44g/mol\times 425}\\\\\text{Mass of solute}=\frac{44\times 425\times 0.0905}{1000}=1.7g$

Hence, the mass of carbon dioxide that can be dissolved is 1.7 grams

A solution of pH 5 is diluted 100 times. Find the pH of the resulting solution.

liq [111]

First, we calculate of the concentration of the H+ ions in the solution from the pH given. Then, calculate the new concentration after dilution. Calculation are as follows:

pH = -log[H+]
5 = -log[H+]
[H+] = 1 x 10^-5 M

M1V1 = M2V2
1 x 10^-5 M (V1) = M2(100V1)
M2 = 1 x 10^-7

pH = -log[1 x 10^-7]
pH = 7
