The mixtures of sodium carbonate and calcium nitrate react to precipitate calcium carbonate and sodium nitrate. This reaction is shown by which balanced chemical equation?

a. Na2CO3 (aq) + CaNO3 (aq) → CaCO3 (s) + NaNO3 (aq)

b. CaCO3 (s) + 2NaNO3 (aq) → Na2CO3 (aq) + CaNO3 (aq)

c. CaCO3 (s) + CaNO3 (aq) → 2NaNO3 (aq) + Na2CO3 (aq)

d. Na2CO3 (aq) + Ca (NO3) 2 (aq) → CaCO3 (s) + 2NaNO3 (aq) Eliminate

Jaylin Hester · Answer 1

2Na⁺ + CO₃²⁻ - > Na₂CO₃ - the molecular formula for sodium carbonate

Ca²⁺ + 2NO₃⁻ - - >Ca (NO₃) ₂ - formula for calcium nitrate -

Ca²⁺ + CO₃²⁻ - - > CaCO₃ - it forms calcium carbonate with formula

Na⁺ + NO₃⁻ - - >NaNO₃ - formula for sodium nitrate -

the balanced chemical equation for the reaction is;

Na₂CO₃ (aq) + Ca (NO₃) ₂ (aq) - - > CaCO₃ (s) + 2NaNO₃ (aq)

correct answer is 4
