<span>Mass of CH2 = 12 + 2 = 14 g/mol
The number of CH2s there are.
So since the total mass is 84.2 g/mol.
The solution is
84.2/14 = 6.012 thus the answer is 6
There are 6(CH2)
So the molecular formula is C6H12</span>
Answer:C.people with perfect understanding of science.
Well the answer to number 1 is definitely B
number 2 is B
number 3 is D
Number 4 is C
Hope this helps:)
The choices for this are as follows:
A) gases; solids
B) metals; nonmetals
C) nonmetals; metals
<span>D) reactive; nonreactive
</span>
I think the correct answer is option B. The stair-step line between the pink squares and the yellow squares separates the metals from the nonmetals. Hope this helps.
