Question

1. Write the chemical formula(s) of the product(s) and balance the following reactions. Identify all product phases as either (g)as, (l)iquid, (s)olid or (aq)ueous. Soluble ionic compounds should be written in the form of their component ions.

a) sulfuric acid(aq) + barium nitrate(aq) --->

b) heptane(g) + oxygen(g) --heat-->

c) hydrobromic acid(aq) + sodium hydrogen carbonate(aq) --->

2. Find the net ionic equation for a and c

Answer 1

a) sulfuric acid(aq) + barium nitrate(aq)

Formula equation;
Ba(NO3)2(aq) + H2SO4(aq) -------> BaSO4(s) + 2HNO3(aq)

Ionic equation:
Ba^2+(aq) + 2NO3^-(aq) + 2H^+(aq) + SO4^2-(aq) -------> BaSO4(s) + 2H^+(aq) + 2NO3^-(aq)

Net ionic equation: (obtained by eliminating the spectator ions from both sides)
Ba^2+(aq) + SO4^2-(aq) -------> BaSO4(aq)

b) heptane(g) + oxygen(g)

C7H16 (l) + 11O2 (g) → 7CO2(g) + 8H2O (g)

c) hydrobromic acid(aq) + sodium hydrogen carbonate(aq)

HCl (aq) + NaHCO3 (aq) ---> NaCl (aq) + H2O (l) + CO2 (g)
Ionic Equation
H+ (aq) + Cl- (aq) + Na+ (aq) + CO3(2-) (aq) ---> Na+ (aq) + Cl- (aq) + H2O (l) + CO2 (g)
Net Ionic Equation
H+ (aq) + CO3(2-) (aq) ---> H2O (l) + CO2 (g)

Net ionic equation for a and c is already written, which answer of your second question.
