The formula for alkene is:
C nH 2n
(N is the number of carbon atoms in a molecule)
Answer: Mendeleev's periodic law was that the properties of elements varies periodically with the atomic weight. Moseley's periodic law or modern periodic law is that the properties of elements are periodic function of their atomic number
It determine Gibbs free energy
CH4 (g) + 2O2 (g) --> CO2 (g) + 2H2O (i)
at STP, 1 mol gas = 22.4 L gas. so you have 52.0 L / 22.4 L / mol = 2.32 mol CH4.
According to the balanced reaction, you need 2 mol O2 for every 1 mol CH4. so you need 2 x 2.32 mol = 4.64 mol O2.
hope this help
