Answer:

1) REACTION OF METALS AND DILUTE ACID - DEFINITION

Metals above the copper in the reactivity series can react with dilute acids to form metal salts and hydrogen.The higher up the series the more vigorous the metals will react.

Example is potassium reacts with dilute hydrochloric acid to GIVE potassium chloride and hydrogen gas.

2K+2HCl⟶2KCl+H

2) REACTIONS OF METALS WITH SOLUTIONS OF OTHER METAL SALTS - DEFINITION

REACTIVE metals can displace any metal less reactive than itself from the OXIDE, chloride or sulphate of the less reactive metal in solution or their molten state. If metal A displaces metal B from its solution, it is more reactive than B.

CHEMICAL PROPERTIES OF METAL - DEFINITION

Metals in chemical reactions forms positive ions , for example dissociation of HCl in water forms H

+

ion .

Metals always forms basic oxide and hydroxides on reaction with acid.

REACTION OF METALS WITH BASES - DEFINITION

Base+metals→ base/metals/salt +H

2

2NaOH+Zn→Na

2

ZnO

2

+H

2

Base only reacts with zinc and aluminium

REACTION OF NON-METALS WITH ACID - DEFINITION

Non metals reacts with acid to produce corresponding acids.For example if nitric acid reacts with sulfur ,sulphuric acid is formed.

REACTION OF NON-METALS WITH BASE - DEFINITION

Non-metals reacts with bases to form salt and water.
