Answer: 2 moles of
will be formed.
Explanation:
To calculate the moles :

The balanced chemical equation is:
According to stoichiometry :
2 moles of
give = 2 moles of 
Thus 2 moles of
give =
of 
Thus 2 moles of
will be formed.
Answer:
The correct option is c
Explanation:
The chemical equation for the reaction of Z-4,5-dimethyloct-4-ene and HCl is shown on the first uploaded image
Now looking at the product we see that there are two who has four different groups attached to them this carbon are known as chiral carbons hence the product formed is a pair of diastereomers
C. Ca and Br because they're metals and nonmetals
Chemical change creates a new substance
