B8, (c)the nitrogen is not balance
9 b is wrong
The question asking about a1) Aqueous bromine not ester on question number B9.
How did you find a 40 on question c
Ionic bond is also called electrovalent
Where did the three come from on B3(b) on the hydrogen
B3 part C the answer is 190g of magnesium chloride
B3 part c the answer is 190g of magnesium chloride
On part 3B question c the answer should be 190g sir
Because
MgO——->MgCl2
40g/mol——–>95g/mol
80g———–> X
Then after cross multiply we have something like this
40g/molX = 80g x 95g/mol
When we multiply 80×95 we are getting a 7600mol
40g/molX = 7600mol
40g/mol 40g/mol
Then
X = 190g
: . MgCl2 = 190g
Thank you so much sir
