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)

Answer 1

Answer:

a. Combination Reaction

b. Neutralization Reaction

c. Displacement Reaction

d. Decomposition reaction (Thermal)

Explanation:

a. Two substances react to form a single new substance.

b. Base + Acid gives Salt + H2O

c. Higher reactive metal (Cu) displaces the less reactive metal (Ag) from its salt solution.
