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.

hloride, what is the mass of calcium in

explanation:

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
