What are the respective concentrations (M) of Cu2+ and Cl- afforded by dissolving 0.596mol CuCl2 in water and diluting to 289mL? A 0.00206 and 0.00206 B 2.06 and 4.12 C 0.485 and 0.086 D 0.00206 and 2.06 E 2.06 and 2.06

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

What is the empirical formula of c6h18o3? ch3o c2h5o c2h6o c2h5o5

)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.
