Question

Classify the following into different types, giving reason.
a. CaO(s) + SiO2(g) ———› CaSiO3(g)
b. KOH(aq) + HCl(aq) ———› KCl(aq) + H2O(l)
c. Cu(s) + 2AgNO3(aq) ———› Cu(NO3)2(aq) + 2Ag(s)
d. BaCO3(s) —heat——› BaO(s) + CO2(g)
e. Mg(OH)2 + 2HCl ———› MgCl2 + 2H2O​

Answer 1

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.
