help

Answer 1

This may be way wrong, but I am going to try it anyway.

Well, your friend is incorrect because of the equation.

He wrote "CaCO subscript 3 -> CaO + CO subscript 2", whereas the equation written is not written the correct way.

Reason I say this is because of how it really should we written.

Here's where I think I'm wrong. I think he should've written it CaCO subscript 3 --> CaCO + CO subscript 2 because if you add that together, it would equal CaCO subscript 3.

Let me know if that is wrong, I do not fully know how to add chemical equations yet.
