Question

Write out the skeleton equation and predict the product, then balance the equation. ____Al2(CO3)3 + ____Cu(NO3)2

Answer 1

- The skeleton equation is:

`Al_2(CO_3)_3+Cu(NO_3)_2\text{ }\rightarrow Cu_{}(CO_3)+Al(NO_3)_3`

The products are Cu(CO3) and Al(NO3)3.

- The balanced equation is:

`Al_2(CO_3)_3+3Cu(NO_3)_2\text{ }\rightarrow3Cu_{}(CO_3)+2Al(NO_3)_3`

So, on the reactants side and on the products side are:

- 2 moles of Al.

- 3 moles of C.

- 3 moles of Cu.

- 3 moles of N.

- 27 moles of O.
