Question

Which products would result from the double replacement reaction between `MgCl_2(ag)` and `Na_2CO_3(ag)`?

Answer 1

`MgCl_2(aq) + Na_2CO_3(aq) rarr MgCO_3(s)darr + 2NaCl(aq)`

Explanation:

Magnesium carbonate is fairly insoluble, and thus a fine white precipitate would be macroscopically observed.
