Answer: 1.8 moles Fe and 2.7 moles are produced.
Explanation:
The balanced chemical reaction is:
According to stoichiometry :
3 moles of require 1 mole of
Thus 2.7 moles of will require=
of
Thus is the limiting reagent as it limits the formation of product and
is the excess reagent.
As 3 moles of give = 2 moles of
and 3 moles of
Thus 2.7 moles of will give =
of
and
of
Thus 1.8 moles Fe and 2.7 moles are produced.
Answer:
The correct answer is in an exothermic reaction the energy of the product is less than the energy of the reactants.
Explanation:
Exothermic reaction is a type of reaction that generates heat.As a result in case of an exothermic reaction the energy of the reactant is more than the energy of the product.
That"s why the enthalpy change in an exothermic reaction is always positive .
