Answer:
Numbe of mole of MgO form=12
Explanation:
First calculate the number of mole of produced from 4 mole of
Balance the first reaction:
from the above balanced reaction it is clearly that,
by unitry method,
2 mole of produced 3 mole of
1 mole of produced 1.5 mole of
from 4 mole of mole of produced
hence we have 6 mole of and this total oxygen will react with Mg
Balance the second reaction:
since produced oxygen in first reaction is reacted completely with Mg means Mg is given in excess quantity,
From the second balanced reacion it is clearly that,
1 mole of produced 2 Mole of MgO
hence 6 mole of will produce 12 mole of MgO
Numbe of mole of MgO form=12
