This question is about hydrocarbons. A hydrocarbon has the formula C16H34\text{C}_{16}\text{H}_{34}C16H34.
How many atoms are there in one molecule of C16H34\text{C}_{16}\text{H}_{34}C16H34?
What is the general formula of the homologous series to which C16H34\text{C}_{16}\text{H}_{34}C16H34 belongs?
The hydrocarbon C16H34\text{C}_{16}\text{H}_{34}C16H34 can be cracked to produce one molecule of decane (C10H22\text{C}_{10}\text{H}_{22}C10H22) and two molecules of another compound, WWW. Complete the carbon and hydrogen balance to find the molecular formula of WWW in the reaction: C16H34→C10H22+2W\text{C}_{16}\text{H}_{34} \rightarrow \text{C}_{10}\text{H}_{22} + 2 WC16H34→C10H22+2W
