Question

For the following chemical reaction:
4 H2O → 4 H2 + 2 O2

Determine how many atoms of each element are on each side

Answer 1

Answer:

Subscripts tell the number of atoms of each element in a molecule ... 2 H2(g) + O2(g) → 2 H2O(l) ... 4. Anatomy of a Chemical Equation. Reactants appear on the left side of the equation

Answer 2

decomposition reaction

A: Two hydrogen molecules per oxygen molecule are produced because water (H2O) has a ratio of two hydrogen atoms to one oxygen atom. A decomposition reaction occurs when one reactant breaks down into two or more products.
