Answer 1

Ca(NO₃)₂ + K₂CO₃ => CaCO₃↓ + 2KNO₃

Ca²⁺ + 2NO₃⁻ + 2K⁺ + CO₃²⁻ => CaCO₃ + 2K⁺ + 2NO₃⁻

Ca²⁺ + CO₃²⁻ => CaCO₃

Na₂CO₃ + 2HCl => 2NaCl + CO₂↑ + H₂O

2Na⁺ + CO₃²⁻ + 2H⁺ + 2Cl⁻ => 2Na⁺ + 2Cl⁻ + CO₂ + H₂O

2H⁺ + CO₃²⁻ => CO₂ + H₂O

LiOH + HNO₃ => LiNO₃ + H₂O

Li⁺ + OH⁻ + H⁺ + NO₃⁻ => Li⁺ + NO₃⁻ + H₂O

H⁺ + OH⁻ => H₂O
