Two moles of sucrose are dissolved in eight moles of water. Assume that the solution follows Raoult's Law, but that the vapor pressure of sucrose is negligible, as it is for most solids. The distillation is carried out at 1 atm.
a) The vapor pressure of the solution at 100 degrees celsius is 0.8atm.
b) What temperature is observed at the still-head thermometer during this entire distillation?
What solute particles are present in an aqueous solution of NH4Cl? Express your answer as a chemical formula. If there is more than one answer, separate them by a comma. Include charges where necessary.
The effective nuclear charge tends to decrease from left to right across any period of the periodic table. 3.Electrons in the 2s orbital feel a greater attraction to the nucleus than the 2p electrons and are therefore lower in energy. 4. Valence e..
