Balancing and trading into words

2005

Im in high school and have a question for a school project. I need to balance the equation and translate it into words:

_HCl + _CaCO₃ reacts to produce _CaCl₂+ _H₂O + _CO₂

Eric G
student - Austin, Texas

What is the project? Sounds more like a homework assignment you want somebody else to do for you, Eric. Please do SOME portion of it yourself first.

If water is one of the products of the reaction . . . and you need 2 atoms of hydrogen to make even one molecule of it . . . and if the HCl is the only source of that hydrogen, what is the minimum number of molecules of HCl you could possibly need? And do you know the names of any of those compounds except H₂O?

I don't care what teachers say about "teaching to the test", we need exams a student must pass to be promoted :-)
