Answer:

Chemical change

Explanation:

A chemical change is a change that cannot be reversed. It results in the formation of a new product. For example, the combustion of wood gives carbon dioxide and water and sometimes suit. In other words, in a chemical change, the products are always different from the reactants. The following equation generally governs a chemical change:

KonstantinChe [14]

Answer:

The answer to your question is below

Explanation:

A.

[H₃O⁺] = 2 x 10⁻¹⁴ M

pH = ?

Formula

                                    pH = - log [H₃O⁺]

Substitution

                                    pH = - log [2 x 10⁻¹⁴]

Result

                                    pH = 13.7          

B.

[H₃O⁺] = ?

pH = 3.12

Formula

                                   pH = - log [H₃O⁺]

Substitution

                                   3.12 = - log [H₃O⁺]

                                   10^{-3.12} = [H_{3} O^{+}]

Result

                                  [H₃O⁺] = 7.59 M
