If we combine the reaction of an acid protonating water and the reaction of its conjugate base deprotonating water, the net reac

trasher [3.6K]

After eliminating common terms, the net reaction occurs when we combine the reactions of an acid protonating water and its conjugate base deprotonating water is<u> the autoionization of water.</u>

<h3>What is the autoionization of water?</h3>

The autoionization of water demonstrates that water can react with itself because acids and bases should interact with one another.

Here, the sound should be strange. Additionally, the water molecules should experience a small degree of proton exchange.

Thus, the correct option is c. The autoionization of water.

To learn more about the autoionization of water, refer to the below link:

The question is complete. Your complete question is given below:

a. The acid-base reaction between the acid and its conjugate base.

b. The synthesis of a complex between the acid and its conjugate base.

c. The autoionization of water.

d. None of the above.

An aqueous salt solution is 15.0% mass sodium chloride. How many grams of salt are in 250.0 grams of this solution? Use correct

Shtirlitz [24]

Answer:

37.5 g NaCl

Explanation:

Step 1: Given data

Concentration of NaCl: 15.0% m/m

Mass of the solution: 250.0 g

Step 2: Calculate how many grams of NaCl are in 250.0 g of solution

The concentration of NaCl is 15.0% by mass, that is, there are 15.0 g of NaCl every 100 g of solution.

250.0 g Solution × 15.0 g NaCl/100 g Solution = 37.5 g NaCl

The mole fraction of CO2 in a certain solution with H2O as the solvent is 3.6 × 10−4. What is the approximate molality of CO2 in

nataly862011 [7]

Answer: C) 0.020 m

Explanation:

Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.

$Molality=\frac{n\times 1000}{W_s}$

where,

n = moles of solute

$W_s$ = weight of solvent in g

Mole fraction of $CO_2$ is = $3.6\times 10^{-4}$ i.e. $3.6\times 10^{-4}$ moles of $CO_2$ is present in 1 mole of solution.

Moles of solute $(CO_2)$ = $3.6\times 10^{-4}$

moles of solvent (water) = 1 - $3.6\times 10^{-4}$ = 0.99

weight of solvent = $moles\times {\text {Molar mass}}=0.99\times 18=17.82g$

Molality = $\frac{3.6\times 10^{-4}\times 1000}{17.82g}=0.020$

Thus approximate molality of $CO_2$ in this solution is 0.020 m
