SiO2 + 4HF → SiFe + 2H2O
write 5 possible mole ratios

Here's what I get

Explanation:

SiO₂ + 4HF ⟶ SiF₄ + 2H₂O  

The molar ratios are the same as the coefficients in the balanced equation.

Some of the molar ratios are

 SiO₂:HF = 1:4

SiO₂:SiF₄ = 1:1

SiO₂:H₂O = 1:2

  HF:SiF₄ = 4:1

  HF:H₂O = 4:2

 SiF₄:H₂O = 1:2

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
