Use the reaction to answer the question
Fe₂O₃ + 3H₂SO₄
How many atoms of oxygen will be found in the product(s) of the reaction?
(1 point)
A. 3
B. 12
C. 4
D. 15
I assume your talking "in the balanced equation".
Fe₂O₃ + 3H₂SO₄ ==> Fe2(SO4)3+ 3H2O
15. I see 12 in Fe2(SO4)3 [that's 4 in SO4 and there are three SO4 so 3*4 = 12. Add 3 more in 3H2O to make 15.
To determine the number of atoms of oxygen in the product(s) of the reaction, we first need to balance the equation:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
From the balanced equation, we can see that 1 molecule of Fe₂O₃ produces 3 molecules of H₂O.
Each molecule of H₂O contains 2 atoms of hydrogen and 1 atom of oxygen. Therefore, for every molecule of Fe₂O₃, there are 3 molecules of H₂O, and thus, 3 atoms of oxygen.
So the answer is: A. 3
To determine the number of atoms of oxygen in the products of the Fe₂O₃ + 3H₂SO₄ reaction, we need to balance the equation first. The balanced equation is:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O.
From the balanced equation, we can see that 1 molecule of Fe₂O₃ reacts with 3 molecules of H₂SO₄ to produce 1 molecule of Fe₂(SO₄)₃ and 3 molecules of H₂O.
Next, we need to analyze the chemical formula of Fe₂O₃. From its chemical formula, we can see that it contains two atoms of iron (Fe) and three atoms of oxygen (O).
Therefore, in the reaction, since 1 molecule of Fe₂O₃ is consumed, the number of atoms of oxygen in the reactants is 3 times the number of Fe₂O₃ molecules, which is 3 x 3 atoms of oxygen.
Hence, the correct answer is D. 15 atoms
