When iron metal reacts with sulfuric acid, It produces iron (III) sulfate and hydrogen gas. Balance the equation: Fe + H2SO4 - Fe2(SO4)3 + H2. Explain why it is necessary to balance chemical equations and why coefficients can be added to an equation, but subscripts cannot be changed.

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

answer: i have one answer

acids are substances that ionize (break off) in an aqueous solution to produce hydrogen (h+) ions

explanation:

hope this and sorry i could only come up with one answer!
