Question 1 What happen when carbon react with oxygen?
Question 2 What happen when sulphur react with oxygen?
Reaction Of Non-Metals with Oxygen
Non-Metals react with oxygen to form acidic oxides or neutral oxides.
Carbon form an acidic oxide carbon dioxide.
Sulphur form an acidic oxide sulphur dioxide.
Hydrogen form a neutral oxide water.
The acidic oxides of non-metals turn blue litmus solution to red.
C(s) + O2 (g) ——> CO2 (g)
CO2 (g) + H20 (l) —–> H2CO3 (aq)
S (s) + O2 (g) ——> SO2 (g)
SO2 (g) + H20 (l) —–> H2SO3 (aq)
Reaction of non-metal with water
They do not react with water to evolve hydrogen gas.
Reaction of non-metals with acids
They do not react with dilute acids. They do not displace hydrogen from acids.
Reaction of Non-metals with salt solution
A more reactive non-metal displaces a less reactive non-metal from its salt solution.
Reaction of Non-metal with chlorine
Non-Metals react with chlorine to form covalent chlorides which are non-electrolytes.
Reaction of Non-metals with hydrogen
Non-Metals react with hydrogen to form covalent hydrides.
