Which of the following is/are true? Hydrocarbons contain carbon, hydrogen and oxygen. Alkenes and Alkynes are unsaturated hydrocarbons. An alkane with 5 carbons has a molecular formula of C5H10. Hydrocarbons only contain C-C single bonds. More than one of above is true.

Alkenes and Alkynes are unsaturated hydrocarbons.

Explanation:

Hydrocarbons are compounds containing carbon and hydrogen.

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms.These are called as alkanes. The general formula for these hydrocarbons is . Thus alkane with 5 carbon atoms will have formula of

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is and respectively.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
