Count up the number of atoms on each side of the equation below and write this in the chart.
ivann1987 [24]

Answer:

The equation to this question is unclear. The clear equation is:

CH4 + 2O2 → CO2 + 2H2O

Please find the number of atoms of each element on the reactant and product side below.

Explanation:

An atom is the smallest indivisible part of an element. The atom retains the chemical properties of the chemical element. In order to ensure that a chemical reaction between molecules and compounds is BALANCED, the number of atoms of each element that makes up the molecule/compound must be the same on both the reactants and products side.

In this case, the chemical reaction involves:

CH4 + 2O2 → CO2 + 2H2O

1. Carbon atom (C):

Reactants side = 1 atom

Products side = 1 atom

2. Oxygen atom (O):

Reactants side = 4 atoms

Products side = 4 atoms

3. Hydrogen atom (H):

Reactants side = 4 atoms

Products side = 4 atoms
