This question is about hydrocarbons. A hydrocarbon has the formula C10H22\text{C}_{10}\text{H}_{22}C10H22.
How many atoms are there in one molecule of C10H22\text{C}_{10}\text{H}_{22}C10H22?
What is the general formula of the homologous series to which C10H22\text{C}_{10}\text{H}_{22}C10H22 belongs?
The hydrocarbon C10H22\text{C}_{10}\text{H}_{22}C10H22 can be cracked to produce one molecule of hexane (C6H14\text{C}_6\text{H}_{14}C6H14) 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 XC10H22→C6H14+2X
