I acually habe no idea but I nust want to point out that my toast's brand is Sarah Lee lol
<span>You have to use a Newman projection to make sure that the H on C#2 is anti-coplanar with the Br on C#1. (Those are the two things that are going to be eliminated to make the alkene.)
My Newman projection looks like this when it's in the right configuration:
Front carbon (C#2) has ethyl group straight up, H down/left, and CH3 down/right
Back carbon (C#1) has H straight down, Ph up/left, and Br up/right.
Then when you eliminate the H from C#2 and the Br from C#1, you will have Ph and the ethyl group on the same side of the molecule, and you'll have the remaining H and CH3 on the same side of the molecule.
This is going to give you (Z)-2-methyl-1-phenyl-1-butene.</span>
Answer: Insufficient amount of work provided.
Explanation:
Phosphorus can be prepared from calcium phosphate by the following reaction:
Phosphorite is a mineral that contains 
plus other non-phosphorus-containing compounds. What is the maximum amount of 
that can be produced from 2.3 kg of phosphorite if the phorphorite sample is 75% by mass? Assume an excess of the other reactants.
Answer: Thus the maximum amount of that can be produced is 0.345 kg
Explanation:
Given mass of phosphorite = 2.3 kg
As given percentage of phosphorite is = 
According to stoichiometry:
2 moles of phosphorite gives = 1 mole of
Thus 5.56 moles of phosphorite give= 
of
Mass of 
Thus the maximum amount of that can be produced is 0.345 kg
