Write the molecular and ionic equations of the reactions: calcium hydroxide and nitric acid, sodium carbonate and calcium chloride, barium hydroxide and hydrochloric acid, sulfuric acid and barium nitrate.

Ca (OH) 2 + 2HNO3 = Ca (NO3) 2 + 2H2O – water formed.

Ca ^ (2+) + 2OH ^ (-) + 2H ^ (+) + 2NO3 ^ (-) = Ca ^ (2+) + 2NO3 ^ (-) + 2H2O

2OH ^ (-) + 2H ^ (+) = 2H2O

Na2CO3 + CaCl2 = 2NaCl + CaCO3 – a precipitate formed.

2Na ^ (+) + CO3 ^ (2-) + Ca ^ (2+) + 2Cl ^ (-) = 2Na ^ (+) + 2Cl ^ (-) + CaCO3

CO3 ^ (2-) + Ca ^ (2+) = CaCO3

Ba (OH) 2 + 2HCl = BaCl2 + 2H2O – water was formed.

Ba ^ (2+) + 2OH ^ (-) + 2H ^ (+) + 2Cl ^ (-) = Ba ^ (2+) + 2Cl ^ (-) + 2H2O

2OH ^ (-) + 2H ^ (+) = 2H2O

H2SO4 + Ba (NO3) 2 = 2HNO3 + BaSO4 – a precipitate formed.

2H ^ (+) + SO4 ^ (2-) + Ba ^ (2+) + 2NO3 ^ (-) = 2H ^ (+) + 2NO3 ^ (-) + BaSO4

SO4 ^ (2-) + Ba ^ (2+) = BaSO4
