Answer: 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide.
Explanation:
The balanced chemical reaction is;
is the limiting reagent as it limits the formation of product and
is the excess reagent.
According to stoichiometry :
1 mole of produces = 1 mole of
Thus 2 moles of will produce=
of
Mass of
Thus 190 g of magnesium chloride can be produced by reacting 2 moles of chlorine gas with excess magnesium bromide
The energy of the carbide released is 7262.5MJ.
<h3>What is the energy?</h3>We know that the reaction between calcium oxide and carbon occurs in accordance with the reaction; . The reaction is seen to produce 464.8kJ of energy per mole of carbide produced.
Number of moles of produced = 1000 * 10^3 g/64 g/mol
= 15625 moles of calcium carbide
If 1 mole of transfers 464.8 * 10^3 J
15625 moles of calcium carbide transfers 15625 moles * 464.8 * 10^3 J/ 1 mol
= 7262.5MJ
