Construction crews sometimes use this reaction for welding underwater structures:

Fe2O3 + 2Al → Al2O3 + 2Fe

It's 5.00 I just took it

Gianna Heath · Answer 2

1 mol of Fe2O3 produce 2 mol of Fe

Therefore, 2.5 mol of Fe2O3 will produce 5 moles.

2.5 mol of Fe2O3 = 2.5 (56*2 + 16*3)

= 2.5 (112 + 48)

= 2.5 * 160

= 400g
