Question 5 NECO • 2024 • CHEMISTRY • essay

A 2.00 L sample of hydrogen gas at 25\(^\circ\)C and 1.00 atm is mixed with an excess of copper(II) sulfate solution. The hydrogen reduces copper(II) sulfate according to the balanced equation: \(\text{CuSO}_4 (aq) + \text{H}_2 (g) \rightarrow \text{Cu} (s) + \text{H}_2\text{SO}_4 (aq)\). After the reaction, 1.20 g of copper are collected.

Question Parts

( a )
