Which explanation accounts for where gas planets formed? Question 2 options: Heavy elements form in the outer regions of the disk due to the spinning protostar The inner portions of the disk are warm from the protostar making the light elements move to the outer solar system Light elements spin into the inner regions of the disk due to their mass The inner portions of the disk are cold from the protostar making the heavy elements remain there

the answer is true.

what does the table look like

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.

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
