Number 4 on this website will help you out a lot.

I'll give you a hint on how to start also. Write out what you know for the chemical equation, and then think about what might happen.

Always cryptic answers!  :)  .This is not homework, and though I am in my first year of chemistry, we did this unit a while back and didn't do more than 2 elements per molecule. From those lessons, I would say CaZn+ CO3 for the products, but I am pretty sure that is wrong. Which is why I am asking the question, lol. Thanks for the response though.

Constant thinker forced you to read forum rules.
You question is unprecise. What do you mean under term "heat" - 100, 200, 1000 C or more.
Zn is unable to reduce CaCO3 during warming. Over 800 C CaCO3 decomposes to CaO and CO2. At this temperature Zn will reduce CO2 to CO.
