b) Zinc metal
c) Solid sodium carbonate
2. Performing and observing the following reactions and classifying them into: Unit-I
A. Combination reaction
B. Decomposition reaction
C. Displacement reaction
D. Double displacement reaction
(i) Action of water on quicklime
(ii) Action of heat on ferrous sulphate crystals
(iii) Iron nails kept in copper sulphate solution

3. Observing the action of Zn, Fe, Cu and Al metals on the following salt solutions: Unit-I
i) ZnSO4(aq)
ii) FeSO4(aq)
iii) CuSO4(aq)
iv) Al2 (SO4)3(aq)
Arranging Zn, Fe, Cu and Al (metals) in the decreasing order of reactivity based on the
above result.
