Answers
Answer:
(a) Direct combination (b) Decomposition (c) Displacement (d) Double displacement. The reactions are - (i) Zinc Hydroxide on heating gives zinc oxide & water (ii) Zinc reacts with copper sulphate to give zinc sulphate & copper (iii) Zinc sulphate reacts with ammonium hydroxide to give ammonium sulphate & zinc hydroxide (iv) Molten zinc at high temperatures, burns in air to give zinc oxide.
(a) Direct combination (b) Decomposition
(c) displacement (d) Double displacement. The reactions are - (i) Zinc Hydroxide on heating gives zinc oxide & water (ii) Zinc reacts with copper sulphate to give zinc sulphate & copper (iii) Zinc sulphate reacts with ammonium hydroxide to give ammonium sulphate & zinc hydroxide (iv) Molten zinc at high temperatures, burns in air to give zinc oxide.
