an electric current can be used to decompose water (h₂o) into oxygen (o₂) and hydrogen (h₂). this reaction is represented by the balanced chemical equation below. 2h₂o (l) → 2h₂ (g) + o₂ (g) determine the number of each type of atom in the reactants and products. number of atoms in reactants number of atoms in products h o

Question

Accepted Answer

# Explanation:
## Step1: Calculate atoms in reactants
For $ H $: Coefficient $ 2 $ in $ 2H_2O $, each $ H_2O $ has $ 2 $ $ H $ atoms. So $ 2\times2 = 4 $.
For $ O $: Coefficient $ 2 $ in $ 2H_2O $, each $ H_2O $ has $ 1 $ $ O $ atom. So $ 2\times1 = 2 $.
## Step2: Calculate atoms in products
For $ H $: Coefficient $ 2 $ in $ 2H_2 $, each $ H_2 $ has $ 2 $ $ H $ atoms. So $ 2\times2 = 4 $.
For $ O $: Coefficient $ 1 $ in $ O_2 $, each $ O_2 $ has $ 2 $ $ O $ atoms. So $ 1\times2 = 2 $.

# Answer:
|  | Number of atoms in reactants | Number of atoms in products |

| $ H $ | $ 4 $ | $ 4 $ |
| $ O $ | $ 2 $ | $ 2 $ |
