Question

5. ) Classify the following reactions into different types, giving reason.
(a) CaO(s) + SiO2(g) - CaSiO (s)
(b) KOH(aq) + HCl(aq) - KCl(aq) + H2O(1)
(c) Cu(s) + 2AgNO3(aq) — Cu(NO3)2(aq) + 2Ag(s)
(d) BaCO3(s) beat , BaO(s) + CO2(g)​

Answer 1

Answer:

a. combination reaction

b. double displacement reaction

c. displacement reaction

d. double displacement reaction

Answer 2

Answer:

(a) is combination reaction as two reactants are combining to give one product.

(b) is a double displacement reaction as potassium, which is more reactive than hydrogen is displacing hydrogen from HCl and H combines with OH to form H2O.

(c) is a displacement reaction as Cu is displacing Ag as Cu is more reactive than Ag.

(d) is a decomposition reaction as one reactant is splitting into two products due to a catalyst.
