Answer:
Explanation:
Balance chemical equation:
2Na + Cl₂ → 2NaCl
Step 1:
Na + Cl₂ → NaCl
Left hand side Right hand side
Na = 1 Na = 1
Cl = 2 Cl = 1
Step 2:
Na + Cl₂ → 2NaCl
Left hand side Right hand side
Na = 1 Na = 2
Cl = 2 Cl = 2
Step 3:
2Na + Cl₂ → 2NaCl
Left hand side Right hand side
Na = 2 Na = 2
Cl = 2 Cl = 2
Balance chemical equation:
2H₂ + O₂ → 2H₂O
Step 1:
H₂ + O₂ → 2H₂O
Left hand side Right hand side
H = 2 H = 4
O = 2 O = 2
Step 2:
2H₂ + O₂ → 2H₂O
Left hand side Right hand side
H = 4 H = 4
O = 2 O = 2
Chemical equation:
CH₄ + 2O₂ → CO₂ + 2H₂O
Step 1:
CH₄ + O₂ → CO₂ + H₂O
Left hand side Right hand side
C = 1 C = 1
H = 4 H = 2
O = 2 O = 3
Step 2:
CH₄ + O₂ → CO₂ + 2H₂O
Left hand side Right hand side
C = 1 C = 1
H = 4 H = 4
O = 2 O = 4
Step 3:
CH₄ + 2O₂ → CO₂ + 2H₂O
Left hand side Right hand side
C = 1 C = 1
H = 4 H = 4
O = 4 O = 4
