Question

The following data were collected for the preparation of the Copper (i) chloride

in the lab. Atomic masses : Cu = 63.5, Cl = 35.5, H= 1.00 ,N = 14.00, Na = 23.0 ,

C = 12.0 g/mol, respectively

i. Weight of copper	1.150 g
ii Volume of 15.8M nitric acid added	5.80 mL
Iii Weight of Na₂CO₃ added	4.420 g
iv Experimental yield of CuCl obtained	2.970 g
v Theoretical yield of CuCl	?
vi Percent yield of CuCl	?

The following reactions should be useful:

Cu(s) + 4HNO₃((aq) → Cu(NO₃)₂ + 2NO₂(g) + H₂O(l)

ii 2HNO₃(aq) + Na₂CO₃(s) → H₂O(l) + CO₂(g) + 2NaNO₃(aq)

iii. Cu(NO₃)₂(aq) + Na₂CO₃(s) → CuCO₃(s) + 2NaNO₃(aq)

iv. CuCO₃(s) + 2HCl(aq) → CuCl₂(aq) + H₂O(l) + CO₂(g)

v. CuCl₂(aq) +Cu(s) → 2CuCl(s)

Based on the above data, calculate the number of moles of HNO₃ that are in excess.

Also based on the above data , the excess moles of HNO₃ used, and the moles of

Cu(NO₃)₂ produced in the first step, how many grams of sodium carbonate was

added in excess.

The answer choices are given in this format.

HNO₃(excess mols)

Na₂CO₃(excess grams)
