Explanation:
Hydrocarbons are molecules that are made up of hydrogen and carbon atoms only.
They are made up of covalent bonds between the carbon and hydrogen atoms.
There is a wide range of hydrocarbons due to the unique properties of carbon.
Most of the hydrocarbons comes from crude oil, natural gas and coal.
When hydrocarbons burn, they produce water and carbon dioxide alone.
They are used as fuel in industrial processes because they produce heat energy.

Answer:
we need to know which atom you're talking about and then you need to say what the mass number is then we can tell how many electrons there are.
(I think)
He answer is 4.9 the graph to the right really means nothing.
The answer is (1) CaCO3. The bond between C and O is covalent bond. And the bond between Ca2+ and CO3 2- ion is the ionic bond. So the compound CaCO3 satisfy this condition.
