1ch₄ + 2o₂ → 1co₂ + 2h₂o\nelements total # before (reactants) total # after (products)\nc\nh\no\nthis chemical reaction is balanced. true false
Answer
Explanation:
Step1: Count carbon atoms
In reactants, in $CH_4$ there is 1 C atom. In products, in $CO_2$ there is 1 C atom.
Step2: Count hydrogen atoms
In reactants, in $CH_4$ there are 4 H atoms. In products, in $2H_2O$ there are $2\times2 = 4$ H atoms.
Step3: Count oxygen atoms
In reactants, in $2O_2$ there are $2\times2=4$ O atoms. In products, in $CO_2$ there are 2 O atoms and in $2H_2O$ there are 2 O atoms, total $2 + 2=4$ O atoms.
Answer:
| Elements | Total # Before (reactants) | Total # After (Products) |
|---|---|---|
| C | 1 | 1 |
| H | 4 | 4 |
| O | 4 | 4 |
| True |
