Question

complete the following word equations: 1. Metal + Acid = 2. Meatal + oxygen =. 3. Metal + water =​

Answer 1

The general equation for this reaction is: metal + oxygen → metal oxide.

hydrogen = H2

metal + acid - metalacid

metal + oxygen = metal oxide

metal + hydrogen = hydroxide

Answer 2

Answer:

1) Metal+acid → salt + hydrogen An example: nitric acid + calcium → calcium nitrate + hydrogen The salt that is produced depends upon which acid and which metal react.

2) A metal reacts with oxygen, a metal oxide forms. The general equation for this reaction is: metal + oxygen → metal oxide.

3)Metals form respective metal hydroxide and hydrogen gas when they react with water. Most of the metals do not react with water. ... Reaction of sodium metal with water: Sodium metal forms sodium hydroxide and liberates hydrogen gas along with lot of heat when it reacts with water.
