What is 4 hydrogen and 10 carbon make?

Four hydrogen atoms and ten carbon atoms can combine to form a hydrocarbon compound. The most straightforward combination would be decane (C10H22), which is a straight-chain alkane. However, with only four hydrogen atoms, they could also participate in forming various other structures or derivatives, such as branched hydrocarbons or functionalized compounds, depending on the arrangement and bonding of the atoms.
