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

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

the answer is d : ) have a good da
