Answer :
In the given reaction, reactants are Cd(NO₃)₂ and H₂S, and products are CdS and HNO₃.
What are reactants?
Those species which react with each other in a chemical reaction for the formation of new specie is know as reactants.
Given chemical reaction is:
Cd(NO₃)₂(aq) + H₂S(g) → CdS(s) + 2HNO₃(aq)
In the above reaction initialy Cd(NO₃)₂ and H₂S react with each other for the formation of new products CdS and HNO₃. So, here Cd(NO₃)₂ and H₂S are reactants.
Hence, Cd(NO₃)₂ and H₂S are reactants and CdS and HNO₃ are products.
