PLEASE NOTE: I ONLY NEED THE ANSWER FOR 1.3
Question 1
Acid spills are often neutralized with sodium carbonate or
sodium hydrogen carbonate. For the neutralization of acetic acid,
the unbalanced equations are given below:
1. CH3CO2H (l) + Na2CO3 (s) → CH3CO2Na (aq) + CO2 (g) + H2O
(l)
2. CH3CO2H (l) + NaHCO3 (s) → CH3CO2Na (aq) + CO2 (g) + H2O
(l)
1.1 Balance both reactions by writing the
stoichiometric coefficients in the spaces before each compound. If
the stoichiometric coefficient is one (1), please write a 1 in the
space provided
1.2 How many kilograms of each alkaline
substance is needed to neutralize a 1000 litre spill of pure acetic
acid (density of acetic acid = 1.049 g/mL)? Show all your
calculations.
(Given: MCH3COOH = 60.04 g.mol-1 ; MNa2CO3 = 106 g.mol-1 ;
MNaHCO3 = 84.01 g.mol-1 ; MH2O = 18.02 g.mol-1 ; MCO2 = 44 g.mol-1
))

1.3 Calculate ΔHo (in kJ) for each reaction and
indicate whether each reaction is exothermic or endothermic by
nature. Find the rest of the standard enthalpies of formation, (ΔH0
f ) that you will need yourself in the literature.
(Given: ΔH0 f for CH3CO2Na(aq) = - 726.1
kJ/mol)
