Answer 2

Copper(ii) sulfate is the limiting reactant when 289g of copper(ii) sulfate reacts with 189g of zinc.

Step-by-step explanation:

In order to determine the limiting reactant, we need to compare the number of moles of each reactant. To find the moles, we divide the given mass by the molar mass of each compound.

For copper(ii) sulfate (CuSO4):

Mass = 289g, Molar mass = 63.55g/mol (copper) + 32.07g/mol (sulfur) + 4(16.00g/mol) (oxygen) = 159.62g/mol

Moles = 289g / 159.62g/mol = 1.8104 mol

For zinc (Zn):

Mass = 189g, Molar mass = 65.38g/mol

Moles = 189g / 65.38g/mol = 2.8906 mol

From the given masses, we can see that there are fewer moles of copper(ii) sulfate compared to zinc. Therefore, copper(ii) sulfate is the limiting reactant.
