7. Write metals reaction with oxygen and acid with chemical equation.
Answers
Explanation:
REACTION WITH BASE - DEFINITION
concept
Metals give hydrogen gas when they react with a base.Reaction of non-metals with bases are complex.
REACTION WITH OXYGEN - DEFINITION
concept
Both metals and non-metals when burnt in oxygen form their oxides. Oxides of metals are basic in nature and oxides of non-metals are acidic in nature.
REACTIONS WITH ACIDS - DEFINITION
concept
Metals give hydrogen gas when they react with dilute acid.Generally, non-metals do not react with dilute acid.
REDUCING NATURE OF METALS - DEFINITION
A reducing agent is an element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction. Since the reducing agent is losing electrons, it is said to have been oxidized.Metals are good reducing agents as they have unpaired electrons in their valence shell ready to be donated.
Answer:
Metals, on being burnt in air, react with the oxygen to form metal oxides.
