Answer: 1.77 kg of manganese (IV) oxide reacts to produce 1.12kg of manganese metal.
Explanation:
The balanced chemical equation is:
To calculate the moles, we use the equation:
moles of manganese =
According to stoichiometry :
3 moles of is produced by = 3 moles of
Thus 20.4 moles of is produced by = of
Mass of (1kg=1000g)
Thus 1.77 kg of manganese (IV) oxide reacts to produce 1.12kg of manganese metal.
Balanced Equation: 2Mg + O2 ➡️ 2MgO
125 x 2= 250 102 x 2= 204
250 + 204= 454
So the answer should be 454 grams of magnesium oxide should be produced.
