Answer to Question #129018 in General Chemistry for mike

Question

Complete and balance these typical acid reactions.
a). CuO(s) + HCI(aq)
b). Na2CO3(s) + HCI(aq)
c). NaOH(aq) + H3PO4(aq)
d). Ni(OH)2(aq) + CH3COOH(aq)
e). NH4HCO3(s) + CH3COOH(aq)

Answer 1

a). CuO(s) + 2HCI(aq) → CuCl₂(s) + H₂O(aq)

b). Na₂CO₃(s) + 2HCl(aq) → H₂O(aq) + CO₂(g) + 2NaCl(aq)

c). 3NaOH(aq) + H₃PO₄(aq) → Na₃PO₄(aq) + 3H₂O(aq)

d). Ni(OH)₂(aq) + 2CH₃COOH(aq) → Ni(CH₃COO)₂(aq) + 2H₂O(aq)

e). 8NH₄HCO₃(s) + 9CH₃COOH(aq) → 8CH₄COONH₄(s) + 6H₂O(aq) + 10CO₂(g)
