Question

4Fe + 3O2 → 2Fe2O3

Iron combines with oxygen to form rust. Given the chemical reaction, how many grams of rust would be produced if 3 grams of reactants were consumed?
A) 0 grams
B) 1 gram
C) 3 grams
D) 7 grams

Answer 1

the answer is 3 grams

Answer 2

C, 3g

Step-by-step explanation:

4Fe + 3O2 = 3g

Since the number of atoms are same on the both sides of equation same amount of rust will be produced. Therefore 3g of Fe2O3 will be produced.
