Ascientist researching methods to convert used motor oil into gasoline would most likely be investigating which process? a. joining molecules into longer chainsb. breaking molecules into smaller chainsc. changing straight chains into ringsd. changing rings into straight chains

Answer is: B.breaking molecules into smaller chains.

Gasoline consists of hydrocarbons with between four and twenty carbon atoms (4-20 C atoms) and motor oil consists of hydrocarbons with between 18 and 34 carbon atoms per molecule, so gasoline has smaller chains than motor oil.

Gasoline is a mixture  of many different hydrocarbons: alkanes (paraffins), cycloalkanes  and alkenes (olefins).

Most motor oils are made from a heavier, thicker petroleum hydrocarbons.

I think the correct answer from the choices listed above is option B. A scientist researching methods to convert used motor oil into gasoline. Most likely he would be investigating breaking molecules into smaller chains since gasoline contains organic substances that has smaller chains. Hope this answers the question.

the ratio of the conjugate base to the acid required to attain the desired ph.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
