Answer:
5.34 moles of are required to produce 3.56 mol of
.
0.83 moles of water react with 2.5 moles of .
Explanation:
i)
Moles of we want to produce = 3.56 moles
According to reaction, 2 moles of are obtained from 3 moles of
Then 3.56 moles of will be obtained from :
of
5.34 moles of are required to produce 3.56 mol of
.
ii)
Moles of = 2.5 moles
According to reaction,3 moles of reacts with 1 mole of
,then 2.5 moles of
will react with :
of
0.83 moles of water react with 2.5 moles of .
