Answer:
2 Fe + 3 (H2SO4) = Fe2(SO4)3 + 3H2
Step-by-step explanation:
Hello, always remember that balancing equations is having one side(the reactants) equal to the same amount as the other side(the products). In this example you would like to look on each side and see what has more of what and how you can equal it.
1. First add a 2 Coefficient to Fe because there is 2 Fe on the product side due to Fe2(SO4)3
2. In Fe2(SO4)3 we can see the 3 at the very end that is distributed to the Sulfur and Oxygen. This means we have to go to the other side due to SO4 only being distributed by nothing, there is no 3 so that is why we put a 3 coefficient in front of H2SO4.
3. Because we put that 3 in front of H2SO4, this cause the hydrogen on the product sign to be imbalanced so we put a 3 coefficient infront of the H2 on the product side.
*Always remember to multiply the coefficient and/or subscripts.
