Hydrocarbons that have one or more double or triple bonds are a. unsaturated b. saturated c. aromatic d. substituted

A. unsaturated

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. The general formula for these hydrocarbons is

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

Aromatic hydrocarbons are those hydrocarbons in which Huckel's rule is obeyed. Example: Benzene

Substituted hydrocarbons are those hydrocarbons in which hydrogen is replaced by some other element. Example:

1.43 x 10^-11 j the guy commented the awnser just making sure u see it .

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
