Answer:
Answer of Ques. :-
Q.11- Carbon dioxide
Q.12- i- magnesium + oxygen → magnesium oxide
(2 Mg + O 2 → MgO)
ii- Magnesium oxide + water→Magnesium hydroxide
(MgO + H2O → Mg(OH)2)
iii- Fe(s)+CuSO 4 (aq)⟶FeSO 4 (aq)+ Cu(s)
iv- Carbon dioxide + Lime water→ calcium carbonate
Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O.
Q.13- Physical
