Answer 1

N₂ + 3H₂ → 2NH₃

2H₂O → 2H₂ + O₂

CH₄ + 2O₂ → CO₂ + 2H₂O

Step-by-step explanation:

A) Make ammonia:

Chemical equation:

N₂ + H₂ → NH₃

Balanced chemical equation:

N₂ + 3H₂ → 2NH₃

Step one:

N₂ + H₂ → NH₃

N = 2 N = 1

H = 2 H = 3

Step 2:

N₂ + 3H₂ → 2NH₃

N = 2 N = 1

H = 2×3 = 6 H = 3×2 = 6

Step 3:

N₂ + 3H₂ → 2NH₃

N = 2 N = 1×2 = 2

H = 2×3 = 6 H = 3×2 = 6

B) separate water:

Chemical equation:

H₂O → H₂ + O₂

Balanced chemical equation:

2H₂O → 2H₂ + O₂

Step one:

H₂O → H₂ + O₂

H = 2 H = 2

O = 1 O = 2

Step 2:

2H₂O → H₂ + O₂

H = 2×2 = 4 H = 2

O = 1×2 =2 O = 2

Step 3:

2H₂O → 2H₂ + O₂

H = 2×2 = 4 H = 2×2 = 4

O = 1×2 =2 O = 2

C) Combust methane

Chemical equation:

CH₄ + O₂ → CO₂ + H₂O

Balanced chemical equation:

CH₄ + 2O₂ → CO₂ + 2H₂O

Step one:

CH₄ + O₂ → CO₂ + H₂O

C = 1 C = 1

H = 4 H = 2

O = 2 O = 3

Step 2:

CH₄ + 2O₂ → CO₂ + H₂O

C = 1 C = 1

H = 4 H = 2

O = 2×2 = 4 O = 3

Step 3:

CH₄ + 2O₂ → CO₂ + 2H₂O

C = 1 C = 1

H = 4 H = 2×2 = 4

O = 2×2 = 4 O = 2 + 2 = 4
