Suppse yoy need 3.2 moles of CaO for a reaction. how many grams of CaO must you weigh out?

If you have 4.72 x 10^24 atoms of Carbob how many moled of carbon do you have?

How many atoms can be foubd in 6.7 moles of BR

thats a little if u want the answer just look it up on google thats what i do haha : )

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.
