For each of the following i) write a skeleton equation
ii) write a correct balanced chemical equation
iii) classify reaction by type

1) calcium metal and water react, giving hydrogen gas and calcium hydroxide

2) aluminum metal quickly reacts with the oxygen in the air to produce aluminum oxide

3) hydrogen sulphate (sulphutic acid) and sodium hydroxide react, producing sodium sulphate and water.

4) sodium chloride and oxygen are produced by heating sodium chlorate.

5) silver nitrate and potassium phosphate react together producing silver phosphate and potassium nitrate.

6) aluminum oxide and copper metal are the products of a reaction between copper (II) oxide and aluminum metal.

7)magnesium and phosphorus (P4) react together, producing magnesium phosphide.

8) lead (II) nitrate and potassium iodide react producing lead (II) iodide a bright yellow precipitate and potassium nitrate which stays in solution.
