When only 2.5 mol of are consumed in order to complete the reaction, ________ mol of
are produced.
Answer: Thus when 2.5 mol of are consumed in their reaction, 1.5 mol of
are produced
Explanation:
The balanced chemical equation is:
According to stoichiometry :
5 moles of produce = 3 moles of
Thus 2.5 moles of will produce =
moles of
Thus when 2.5 mol of are consumed in their reaction, 1.5 mol of
are produced
