Question

what is rhe coeffecient for iron after the following reaction is balamced Fe+O2-->Fe2O3

Answer 1

Answer #1

Th given reaction is:

Fe + O2 -> Fe2O3

Balance Fe:

2 Fe + O2 -> Fe2O3

Balance O:

2 Fe + 3/2 O2 -> Fe2O3

Multiply all by 2 to remove fraction:

4 Fe + 3 O2 -> 2 Fe2O3

The equation now balanced.

The coefficient of Fe is 4

Answer: d

Answer 2
