PLS HELP MY HOMEWORK IS DUE IN AN HOUR

Answer 1

Answer: Synthesis

0.84 moles of oxygen

25 moles of $Fe_2O_3$

Explanation:

The balanced chemical equation is:

$4Fe+3O_2\rightarrow 2Fe_2O_3$

This is a synthesis reaction as one product is formed by combination of two reactants.

According to stoichiometry :

a. 2 moles of $Fe_2O_3$ require = 3 moles of $O_2$

Thus 0.56 moles of $Fe_2O_3$ require=$\frac{3}{2}\times 0.56=0.84moles$  of $O_2$

b. 4 moles of $Fe$ give = 2 moles of $Fe_2O_3$  

Thus 50 moles of $Fe$ give =$\frac{2}{4}\times 50=25moles$  of $Fe_2O_3$
