Question

Cucl2 2 na → 2nacl cu you only have 15g of sodium to use for this reaction. how much copper(ii must you combine with the sodium to isolate the maximum amount of copper possible.

Answer 1

The balanced chemical reaction is:

CuCl2 + 2Na → 2NaCl + Cu

We are given the amount of sodium to be used up in the reaction. This will be the starting point for our calculations.

15 g Na ( 1 mol / 22.99 ) ( 1 mol Cul2 / 2 mol Na ) (134.45 g / 1 mol ) = 43.86 g CuCl2 needed to be able to obtain the maximum amount of copper.
