Since both sides have to be equal to each other, subtracting the left side from the right side will leave you with the other reactant.

On the right side, you have 1 sodium, 2 carbon, 5 hydrogen, and 3 oxygen.

If you take away 1 sodium, 1 oxygen, and 1 hydrogen you are left with 2 carbon, 4 hydrogen, and 2 oxygen.

This is written as CH3COOH
AKA Acetic Acid

What is the pH of a 0.222 M acetic acid solution?
Oksi-84 [34.3K]

pH=2.7

<h3>Further explanation</h3>

Acetic acid = weak acid

\tt [H^+]=\sqrt{Ka.M}

Ka = acid ionization constant

M = molarity

Ka for Acetic acid(CH₃COOH) : 1.8 x 10⁻⁵

\tt [H^+]=\sqrt{1.8\times 10^{-5}\times 0.222}\\\\=0.001998=1.998\times 10^{-3}

\tt pH=3-log~1.998=2.7

Nitrogen dioxide reacts with water to form nitric acid and nitrogen monoxide according to the equation: 3NO2(g)+H2O(l)→2HNO3(l)+
Vesnalui [34]

Answer:

2 mol NO2

Explanation:

                                      3NO2(g)+H2O(l)→2HNO3(l)+NO(g)

from reaction                3 mol        1 mol

given                           11 mol          3 mol

for 3 mol NO2  -----   1 mol H2O

for x mol NO2  -----   3 mol H2O

3:x = 1:3

x = 3 *3/1 = 9 mol NO2

So, for 3 mol H2O are needed only 9 mol NO2.

But we have 11 mol NO2. So, NO2 is in excess, and

11 mol NO2 - 9 mol NO2 = 2 mol NO2 will be left after reaction.
