Answer:
PLEASE MARK MY ANSWER AS THE BRAINLIEST
Explanation:
Na + Cl₂ → NaCl
= 2Na + Cl₂ → 2NaCl
--------------------------------
H₂ + O₂ → H₂O
= 2H₂ + O₂ → 2H₂O
--------------------------------
C₃H₄ + O₂ → CO₂ + H₂O
= C₃H₄ + 4O₂ → 3CO₂ + 2H₂O
---------------------------------
CaCO₃ → CaO + CO₂ IT IS ALREADY BALANCED
---------------------------------
H₂O₂ → H₂O + O₂
= 2H₂O₂ → 2H₂O + O₂
---------------------------------
Mg + HCl → MgCl₂ + H₂
= Mg + 2HCl → MgCl₂ + H₂
---------------------------------
NaOH + HCl → NaCl + H₂O IT IS ALREADY BALANCED
---------------------------------
Al + Br₂ → AlBr₃
= 2Al + 3Br₂ → 2AlBr₃
---------------------------------
Ca + O₂ → CaO
= 2Ca + O₂ → 2CaO
---------------------------------
Fe₂O₃ + C → Fe + CO₂
= 2Fe₂O₃ + 3C → 4Fe + 3CO₂
----------------------------------
HNO₃ + Mg(OH)₂ → Mg(NO₃)₂ + H₂O
= 2HNO₃ + Mg(OH)₂ → Mg(NO₃)₂ + 2H₂O
----------------------------------
Ca + HCl → CaCl₂ + H₂
= Ca + 2HCl → CaCl₂ + H₂
----------------------------------
MgCl₂ + NaOH → Mg(OH)₂ + NaCl
= MgCl₂ + 2NaOH → Mg(OH)₂ + 2NaCl
----------------------------------
BaCl₂ + Li₂SO₄ → LiCl + BaSO₄
= BaCl₂ + Li₂SO₄ → 2LiCl + BaSO₄
----------------------------------
H₂SO₄ + RbOH → Rb₂SO₄ + H₂O
= H₂SO₄ + 2RbOH → Rb₂SO₄ + 2H₂O
