1.

a.) The color of <u>Aqueous solution</u> turns <u>light green</u> from <u>blue</u>, due to formation of <u>iron sulphate</u> .

b.) The color of the <u>Aqueous solution</u> turns <u>colorless</u> from <u>blue</u> due to formation of <u>zinc sulphate</u>.

2. <u>Bells</u> used in temples aren't made up of wood because wood isn't <u>sonorous</u> and hence can't produce <u>ringing sound</u>, and hence metals are used in making bells.

3. <u>phosphorous</u> is kept in water because it is <u>highly reactive</u> and reacts vigorously with air if left free in atmosphere .

4.

a.) CuSO4 + Mg =》MgSO4 + Cu

this is a <u>single displacement reaction</u>, where <u>Magnesium</u> being more reactive than <u>Copper</u>, displaces copper from its compound (copper sulphate) to form <u>magnesium sulphate</u>.

b. H2SO4 + Zn =》ZnSO4 + H2

this is a <u>single displacement</u><u> </u><u>reaction</u>,

where <u>Zinc</u> being more reactive than

<u>hydrogen</u>, displaces hydrogen from its

compound (sulphuric acid) to form <u>Zinc</u><u> </u><u>sulphate</u>.
