What is C3H8(g) + 5O2(g) as a hydrocarbon reaction

1.5 moles C3H8 x (5 moles O2 / 1 mole C3H8) = 7.5 moles O2

Explanation:

.these are the coefficients of the balanced equation

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
