Answer 1

Answer:

it's Opt.A because opt.A is a combination reaction as oxygen and carbon combine to form carbon dioxide . And thus A matches with q.

B suits most with r cause it's a decomposition reaction because its a compound of silver and Bromine( cz silver's chemical symbol is Au and that for

bromine is Br ).

C) , it's a displacement reaction cz zinc (Zn) , being more reactive than copper(Cu) displaces copper from its solution of copper sulphate and thus forms a solution of zinc sulphate along with copper .(as u can see in the reaction in the page u clicked and posted it on this platform.

Thus, the last one I.e D is simply oxidation.

So at last we get the order as A-q;B-r;C-p and D -s.
