Question

which of the following statement is characteristic of non metal.
a)they form acidic acida
b)they are malleable and ductile
c)they replace hydrogen from acids
d)they form basic oxides​

Answer 1

Answer:

C

Explanation:

it's correct answer.....

Answer 2

Answer:

a)they form acidic acids

Explanation:

ex: S(sulphur) or C(carbon) or P or N

They all form acids when their oxides are mixed with water.

1. S + O₂ = SO₂

   SO₂ + H₂O = H₂SO₃

2. 2SO₂ + O₂ = 2SO₃

    SO₃ + H₂O = H₂SO₄

3. C + O₂ = CO₂

   CO₂ + H₂O = H₂CO₃

4. N₂ + 2O₂ = 2NO₂

   NO₂ + H₂O = H₂NO₃

5. 4P + 5O₂ = 2P₂O₅

   P₂O₅ + 3H₂O = 2H₃PO₄
