What do scientists call hydrocarbons like methane and ethane?
Alkanes

CnH2n+2
6 of 11
What does this mean?
If we know the number of carbon atoms in alkane (n), then we can calculate the number of hydrogen atoms. To do that we multiplied the number of carbon atoms by 2 and then add 2.

Where is crude oil found?
Plastics, Petrol, Medicines and cosmetics
8 of 11
How would you calculate this using Methane?
Methane has one carbon atom. n=1. To work out the number of hydrogen atoms,we multiply 1 by 2 and then add 2. This means that methane contains four atoms of hydrogen.

What are Alkanes?
Saturated molecules
10 of 11
