Consider the balanced equation below. 3fe+4h_2o -> fe_3o_4+4h_2 what is the mole ratio of fe_3o_4to fe? a. 1: 3 b. 1: 4 c. 3: 1 d. 4: 3

A. 1:3

The equation shows that 1 mol Fe_3_O4 ≡ 3 mol Fe.

∴ The mole ratio is Fe_3_O4:Fe = 1:3.

“B. 1:4” is incorrect. It is the mole ratio of Fe_3O_4:H_2O and of Fe_3O_4:H_2.

“C: 3:1” is incorrect. It is the mole ratio of Fe:Fe_3O_4.

“D: 4:3” is incorrect. It is the mole ratio of H_2O:Fe and of H_2:Fe.

58750.08068 is the answer i think

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
