If the totaling of bromine to cis-cinnamic acid uses the
same mechanism or device as the addition to trans-cinnamic acid, addition of
bromine only transpires on the top (syn) and not the bottommost face (anti). Therefore,
bromine added to cis-cinnamic only adds to the same face (syn addition) as a
result producing only threo dibromides.

Look at my answer to the last one, and see if you can solve this one on your own!
After you try it, I can let you know if you got it right :)
Hello There!
The only particles that can be lost, gained or shared are electrons.
These are negative sub atomic particles.
A covalent bond is when the electrons are shared.
An Ionic bond is when the electrons are gained or lost.
Hope This Helps You!
Good Luck :)

Answer:
The empirical formula is = 
Explanation:
Given that:- Mass of nickel = 2.241 g
Mass of the oxide formed = 2.852 g
Mass of the oxygen reacted = Mass of the oxide formed - Mass of nickel = 2.852 g - 2.241 g = 0.611 g
Molar mass of nickel = 58.6934 g/mol
Moles of nickel = 
= 0.03818 mol
Molar mass of oxygen = 15.999 g/mol
Moles of nickel = 
= 0.03818 mol
Taking the simplest ratio for Ni and O as:
0.03818 : 0.03818 = 1 : 1
<u>The empirical formula is =
</u>
