42 moles of C are reacted with 54 moles of H2O. How many moles of CH3 are formed?2C + 2H2O ->CH, +CO,*

b. examine and describe cells

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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.
