What reaction would the chemical equation 2h2o --> 2h2+o2 represent? a) replacement of water b) combustion of water c) decomposition of water d) formation of water

Answer;

C. Decomposition of water

Explanation;

A decomposition reaction occurs when one reactant breaks down into two or more products.This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.

The equation for the decomposition of water; 2H2O --> 2H2+O2

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
