Answer to Question #186512 in Chemistry for Maria Roman

Question

Number of atoms before reaction

CH4+2 O2 ——> CO2 + 2 H2O

Number of atoms after reaction

CH4+2 O2 ——> CO2 + 2 H2O

Answer 1

Solution:

CH₄ + 2O₂ → CO₂ + 2H₂O

Number of atoms before reaction:

One carbon atom (C); four hydrogen atoms (H); four oxygen atoms (O).

Hence, 9 atoms before reaction.

Number of atoms after reaction:

One carbon atom (C); four hydrogen atoms (H); four oxygen atoms (O).

Hence, 9 atoms after reaction.

This chemical equation is balanced.
