HEY I NEED A ANSWER RIGHT NOW IT'S MISSING AND MY TEACHER ARE GRADING THEM NOW YOU WILL BE MARKED BRAINIEST

Answer 1

Answer:

56.6 g Fe2O3

Explanation:

Answer 2

Balanced equation is given by

$\\ \rm\Rrightarrow 4Fe+3O_2\longrightarrow 2Fe_2O_3$

On both sides

• Fe=4
• O=6

Hence balanced

Now

• 3mols of O_2 produces 2 mol Fe_2O_3
• 1 mol O_2 produces 2/3=0.6mol Fe_2O_3

Moles of O_2:-

• 17/32= 0.5mol

Moles of Fe_2O_3;

• 0.5(0.6)=0.3mol

Mass of Fe_2O_3:-

• Moles (Molar mass)
• 159.7(0.3)=47.91g
