Sorry that is Incorrect
The correct answer is FeSO4. All of the other answers are incorrect. Here is why:
- FeH2--> This is incorrect because the hydrogen in the acid on the reactants side is positive, meaning that it must remain positively charged on the products side too.
- SO4Fe--> This is incorrect because the SO4 is negative on the reactants side, meaning that it must remain negative on the products side too.
- H2SO4--> The Hydrogen on the reactants side does not get involved with the creation of the salt, rather it is involved in making the hydrogen gas, which is one of the products of an acid reaction with a metal.
- FeSO4--> This is correct!
