This question is about hydrocarbons. A hydrocarbon has the formula C10H22\text{C}_{10}\text{H}_{22}C10​H22​.

a.

How many atoms are there in one molecule of C10H22\text{C}_{10}\text{H}_{22}C10​H22​?

[1]
b.

What is the general formula of the homologous series to which C10H22\text{C}_{10}\text{H}_{22}C10​H22​ belongs?

[1]
c.

The hydrocarbon C10H22\text{C}_{10}\text{H}_{22}C10​H22​ can be cracked to produce one molecule of hexane (C6H14\text{C}_6\text{H}_{14}C6​H14​) and two molecules of another compound, XXX. Complete the carbon and hydrogen balance to find the molecular formula of XXX in the reaction: C10H22→C6H14+2X\text{C}_{10}\text{H}_{22} \rightarrow \text{C}_6\text{H}_{14} + 2 XC10​H22​→C6​H14​+2X
