Answer:
<em>320 gm </em>
Explanation:
4 Fe + 3 O2 ----> 2 Fe2O3 How many moles of iron(III) oxide, Fe2O3 , will be produced if 4 moles of iron, Fe, are consumed
for every 4 moles of Fe, 2 m<em>oles of Fe</em>2O3 are produced.
<em>Fe2O3 has a molar mass of (56 X 2) + (16 X 3) = 112 + 48 =160</em>
<em>160 X 2 =320 gm </em>
Answer:
a is a chemical change b is chemical change c is a physical change d is a physical change e is a chemical change
Answer: 61.3 g of will be produced from the given masses of both reactants.
Explanation:
To calculate the moles, we use the equation:
a) moles of
b) moles of
According to stoichiometry :
5 moles of require 4 moles of
Thus 2.84 moles of require= of
Thus is the limiting reagent as it limits the formation of product.
As 5 moles of give = 6 moles of
Thus 2.84 moles of give = of
Mass of
Thus 61.3 g of will be produced from the given masses of both reactants.
