explain displacement reaction in brief?
and give a brief description on reaction of metals and non metals with oxygen and water
Answers
given below is displacement reaction
Answer:
Displacement reactions occur when a metal from the electrochemical series is mixed with the ions of a metal lower down in the electrochemical series. The atoms of the more reactive metal push their electrons on to ions of the less reactive metal.
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.
CHEMICAL PROPERTIES - DEFINITION
Metals are very reactive. Metals tend to lose electrons easily and form positively charged ions. Therefore metals are called electropositive elements.Non-metals accept electrons readily because they have high electronegativities.
REACTION OF NON-METAL WITH OXYGEN - DEFINITION
When non-metals react with oxygen the non-metallic oxide is formed. Non-metallic oxides are acidic.
REACTION OF NON-METAL WITH WATER - DEFINITION
Metals react with water to form hydroxides , generally non-metal do not react with water.
