Balance the molecular Equations after adding the correct formulas of the product

Question

Balance the molecular Equations after adding the correct formulas of the product. Phase label products by following the solubility rules. Write net ionic Equations and phase label all. Ionic equations are not needed. Balance the molecular equations by adding coefficient before the formulas.

a) Molecular Eq HNO3 (aq) + K2CO3 (aq)

Net Ionic Eq.

b) Molecular Eq. Pb(NO3)2 (aq) + KCl (aq)

Net Ionic Eq.

c) Molecular Eq. Mg(OH)2 (aq) + HCl (aq)

Net Ionic Eq.

d) Molecular Eq. NH4Cl (aq) + LiOH (aq)

Net Ionic Eq.

Explanation / Answer

a)

2 HNO3 (aq) + K2CO3 (aq) --------> 2 KNO3 (aq) + H2O (l) + CO2 (g)

Net ionic equation : 2 H+ (aq) + CO3 2- (aq) --------> H2O (l) + CO2 (g)

b)

Pb(NO3)2 (aq) + 2 KCl (aq) PbCl2 (s) + 2 KNO3 (aq)

Net ionic equation : Pb+2 (aq) + 2 Cl- (aq) -------> PbCl2 (s)

c)

Mg(OH)2 (aq) + 2 HCl (aq) MgCl2 (s) + 2 H2O (aq)

Net ionic equation : Mg+2 (aq) + 2 Cl- (aq) -------> MgCl2 (s)

d)

NH4Cl (aq) + LiOH (aq) NH3 (g) + H2O (l) + LiCl (aq)

Net ionic equation : NH4+ (aq) + -OH (aq) --------> NH3 (g) + H2O (l)
