iii. acid​

Answer 1

Answer:

Write the reactions of a metals with: oxygen :-

magnesium + oxygen → magnesium oxide

Write the reactions of a metals with: water

Reactions of metals with water

When a metal reacts with water, a metal hydroxide and hydrogen are formed.

For example:

sodium + water ➞ sodium hydroxide + hydrogen.

calcium + water ➞ calcium hydroxide + hydrogen.

The apparatus below is used to react calcium with water and collect the gas.

Write the reactions of a metals with:  acid​ :-

When an acid reacts with metal, a salt and hydrogen are produced: acid + metal → salt + hydrogen An example: nitric acid + calcium → calcium nitrate + hydrogen The salt that is produced depends upon which acid and which metal react.
