What is the driving force of the deep water ocean conveyor belt? -Winds push the deep water into the Pacific and Indian Oceans.

-Gravity from the Moon pulls the deep water toward the equator.

-The spinning of Earth makes the deep water current run in circular paths.

-Very cold temperatures create very dense water which pushes the deep current along.

indium, and thallium have three electrons i think

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
