Copper(II) sulfate and sodium hydroxide react according to the equation:
CuSO4(aq)+2NaOH(aq)→Cu(OH)2(s)+Na2SO4(aq) \text{CuSO}_4(\text{aq}) + 2\text{NaOH}(\text{aq}) \rightarrow \text{Cu(OH)}_2(\text{s}) + \text{Na}_2\text{SO}_4(\text{aq}) CuSO4(aq)+2NaOH(aq)→Cu(OH)2(s)+Na2SO4(aq)In an experiment, 40.0 cm3 of a 0.200 mol dm-3 solution of each compound are mixed together.
Which amount, in mol, of copper(II) hydroxide is formed?
4.00×10−34.00 \times 10^{-3}4.00×10−3
8.00×10−38.00 \times 10^{-3}8.00×10−3
4.00×10−24.00 \times 10^{-2}4.00×10−2
8.00×10−28.00 \times 10^{-2}8.00×10−2
