Answer:
solution given:
Explanation:
4Fe +3O2------------>2Fe2O3
4mole. 3mole. 2 mole
224g. 96g. 320g
we have
224 g of fe needed to react completely with 96 g of O2
500g of fe needed to react completely with
96 ×500/224=214.3g of O2
214.3g of O2 is a required answer.
"The mass of [tex]O_{2}[/tex] will be 214.3g to completely react with 500 g of Fe."
What is mass?
A physical body's mass is the amount of matter it contains. It can also use to measure moment of inertia, or the resistance to movement when one net force is exerted. The degree of an object's gravitational pull to other bodies is also determined by its mass. The kilogram is the SI base unit of mass.
The reaction between Fe and [tex]O_{2}[/tex] can be written as:
[tex]4Fe+3O_{2}[/tex] → [tex]2Fe_{2}O_{3}[/tex]
It can be see that 4 mole of iron is reacts with 2 mole of oxygen and its form 2 mole of [tex]2Fe_{2}O_{3}[/tex]
So, 224 g of iron is needed in the reacted with oxygen (96 g).
500 g of iron will be needed = 96× 500/224= 214.3g of [tex]O_{2}[/tex].
