chemical properties of non metals rection with oxygen ,water ,acid
Answers
Most nonmetals do not react with air in room temperature. White phosphorus is the only nonmetal that reacts with air to form its oxide by burning. Usually, nonmetals do not react with water. Except for Chlorine, chlorine dissolves in water to form an acidic solution.
1. Reaction of Non-metals with Oxygen
All non-metals react with oxygen to form acidic or neutral oxides. For example, Carbon forms acidic carbon dioxide on reacting with oxygen.
C + O2 CO2
Carbon Carbon Dioxide
In the same way sulphur reacts with oxygen of air to form acidic sulphur dioxide.
S + O2 SO2
Sulphur Sulphur Dioxide
2. Reaction of Non-metals with Water
Non-metals do not react with water.
3. Reaction of Non-metals with Dilute Acids
Non-metals do not react with dilute acids and don’t displace hydrogen from dilute acids, because non-metals are electron acceptor. So, they cannot supply electrons to H+ ions. So, they do not displace hydrogen from dilute acids.
4. Reaction of Non-metals with Chlorine
Non-metals react with chlorine to form covalent chlorides. For example,
H2 + Cl2 2HCl
Hydrogen Chlorine Hydrogen chloride
P4 + 6Cl2 4PCl3
Phosphorous Chlorine Phosphorous trichloride
5. Reaction of Non-metals with Hydrogen
Non-metals react with hydrogen to form covalent Hydrides. For example,
H2 + S H2S
Hydrogen sulphur Hydrogen sulphide
N2 + 3H2 2NH3
Nitrogen Hydrogen Ammonia
