Rxn - Non metals + o2

Question 1

How does the rxn take place?

Answer 1

Non metal + oxygen -> acidic oxides or neutral oxides

Question 2

Acidic oxides of non metals dissolve in water to give?

Answer 2

acids

Question 3

1) carbon

Answer 3

C + O2 -> CO2 (Acidic oxide)\

CO2 + H20 -> H2CO3 (Carbonic acid)

Question 4

2) Sulphur (Yellow solid)

Answer 4

S + O2 -> SO2 (Acidic oxide)

SO2 + H20 -> H2SO3

Question 5

Non metal acidic oxides are called

Answer 5

Anhydrides

Question 6

Phosphorus

Answer 6

P + O2 -> P2O5 (phosphorus pentoxide)

Question 7

carbon monoxide (neutral oxide)

Answer 7

Carbon when given an insufficient supply of oxygen (of air) then it forms a neutral oxide -> Carbon monoxide
2C + O2 -> 2CO neutral oxide

Question 8

Hydrogen (neutral oxide)

Answer 8

2H2 + O2 -> 2H2O (water)

Question 9

these non metal oxides are called covalent compounds bcs

Answer 9

these non metal oxides are called covalent compounds bcs they are formed by the sharing of electrons. They do not contain oxide ions.
