Explanation:
a) The balanced reaction equation is;
K2S + CO(NO3)2 ------> COS + 2 KNO3
b) When we include the states of matter, we have;
K2S(aq) + CO(NO3)2(aq) ----> COS(s) + 2 KNO3(aq)
c) The complete ionic equation is;
2K^+(aq) + S^2-(aq) + Co^2+(aq) + 2NO3^-(aq) ----> CoS(s) + 2K^+(aq) + 2NO3^-(aq)
Net ionic equation;
Co^2+(aq) + S^2-(aq) ----> CoS(s)

To determine the formula mass of beryllium chloride, BeCl₂, we start up with the basis of one mole first.
Basis: 1 mole BeCl₂
To determine the molar mass of BeCl₂, we add up the mass of one mole of beryllium and two moles of chlorine.
1 mol Be = 9 g/mol
1 mol of Cl = 35.45 g/mol
Solving,
molar mass of BeCl₂ = (1 mol Be)(9 g/mol) + (2 mols Cl)(35.45 g/mol)
molar mass of BeCl₂ = 79.9 g
Then, we take into consideration that 1 mol is equal to 6.022 x 10²³ formula units.
formula mass BeCl₂ = (79.9 g/mol)(1 mol/6.022 x 10²³ formula units)
formula mass of BeCl₂ = 1.33 x 10⁻²² g/formula unit
<em>Answer: 1.33 x 10⁻²² g/formula unit</em>
