Express your answer as a chemical equation. Identify all of the phases in your answer.

b.Ca(s)+H2SO4(aq)

Express your answer as a chemical equation. Identify all of the phases in your answer.

c.H2SO4(aq)+Al(OH)3(aq)

Express your answer as a chemical equation. Identify all of the phases in your answer.

d.Na2CO3(s)+H2SO4(aq)

Express your answer as a chemical equation. Identify all of the phases in your answer.

Explanation / Answer

a)

KHC03 on reaction with HCl will producde KCl , C02 and H20

so

the balanced reaction is given by

KHC03 (s) + HCl (aq) ----> KCl (aq) + C02 (g) + H20 (l)

b)

the balanced reaction is given by

Ca (s) + H2S04 (aq) ---> CaS04 (s) + H2 (g)

c)

this is a neutralization reaction

so the balanced reaction is given by

3 H2S04 (aq) + 2 Al(OH)3 (aq) ----> Al2(S04)3 (aq) + 6H20 (l)

d)

the balanced reaction is given by

Na2C03 (s) + H2S04 (aq) ---> Na2S04 (aq) + C02 (g) + H20 (l)
