Balance the equation, complete ionic equation, and net ionic equation for these 3: 1. HgI2+ PbSO4

2. Sodium carbonate and calcium reacts in a single replacement, one of the resulting products immediately decomposes.(you should end up with one balanced equation-3products)

3.CaS+Al

)benzene and toluene form nearly ideal solutions. consider an equimolar solution of benzene and toluene. at 20 °c the vapour pressures of pure benzene and toluene are 9.9 kpa and 2.9 kpa, respectively. the solution is boiled by reducing the external pressure below the vapour pressure. calculate (i) the pressure when boiling begins, (ii) the composition of each component in the vapour, and (iii) the vapour pressure when only a few drops of liquid remain. assume that the rate of vaporization is low enough for the temperature to remain constant at 20 °c.
