Aneutral atom has a mass number of 108 and in atomic number of 47 which atom is this? explain how you know. ^how many protons electrons and neutrons are in this atom. show your calculation or explain how you determine each number an adam with an atomic number of 35 makes an ion with a negative 1 charge. which atom is this? explain how you know. ^ how many electron's does this ion have? explain how you came to this answer

)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.
