Answer:
A3B3
Explanation:
Molecular formula = n x empirical formula
(AB) n = 90
MM of AB = 30 g/mol
30n = 90
Divide both side by the coefficient n i.e 30
n = 90/30 = 3
Molecular formula = n x empirical formula
Molecular formula = n x (AB)
Molecular formula = 3(AB) = A3B3
Yes, because you made a new substance to make a gas.
This is a combustion reaction.
2C6H6 + 9O2➡️ 6CO2 + 6H2O
Don't smoke, drive less, don't let toast burn, use an electrical fire instead of a wood one....
I can't think of anything else.
