Question

WRITE BALANCED, IONIC AND NET EQUATION 1) SODIUM CARBONATE ( Na2CO3) + CALCIUM CARBONATE 2) SODIUM PHOSPHATE ( Na3PO4) + CALCIUM CARBONATE 3) CALCIUM NITRATE ( Ca(NO3)2 + CALCIUM CARBONATE

Answer 1

1.

Balanced equation: Na₂CO₃ (aq) + CaCO₃ (aq) --> Na₂CO₃ (aq) + CaCO₃ (s)

Ionic Equation: 2 Na⁺ (aq) + 2 CO₃^2- (aq) + Ca²⁺ (aq) --> 2 Na⁺ (aq) + CO₃^2- (aq) + CaCO₃ (s)

Net ionic equation: CO₃^2- (aq) + Ca²⁺ (aq) --> CaCO₃ (s)

------------------------------------------------------------------------------------------------------------------------------------

2.

Balanced equation: 2 Na₃PO₄ (aq) + 3 CaCO₃ (aq) --> 3 Na₂CO₃ (aq) + Ca₃(PO₄)₂ (s)

Ionic Equation: 6 Na⁺ (aq) + 2 PO₄^3- (aq) + 3 Ca²⁺ (aq) + 3 CO₃^2- (aq) --> 6 Na⁺ (aq) + 3 CO₃^2- (aq) + Ca₃(PO₄)₂ (s)

Net ionic equation: 2 PO₄^3- (aq) + 3 Ca²⁺ (aq) --> Ca₃(PO₄)₂ (s)

------------------------------------------------------------------------------------------------------------------------------------

3.

Balanced equation: CaCO₃ (aq) + Ca(NO₃)₂ (aq) --> CaCO₃ (s) + Ca(NO₃)₂ (aq)

Ionic Equation: 2 Ca²⁺ (aq) + CO₃^2- (aq) +2 NO₃^- (aq) --> Ca²⁺ (aq) + NO₃^- (aq) + CaCO₃ (s)

Net ionic equation: Ca²⁺ (aq) + CO₃^2- (aq) --> CaCO₃ (s)
