Question

How would you balance: Na2CO3 + BaCl2 --> NaCl + BaCO3?

Answer 1

This is simply partner exchange. Barium carbonate should be insoluble.

Explanation:

`Na_2CO_3(aq) + BaCl_2(aq) rarr 2NaCl(aq) +BaCO_3(s)darr`

Is this equation balanced with respect to mass? How do you know? What do I mean by `BaCl_2(aq)`; how is this different to `BaCO_3(s)`?
