A chemist studying the properties of photo- graphic emulsions needed to prepare 500 mL of 0.18 M AgNO3 (aq). What mass of silver ni- trate must be placed into a 500 mL volumetric ?ask, dissolved, and diluted to the mark with water? Answer in units of g.
The solvolysis of benzyl chloride proceeds via a carbocation intermediate and occurs more rapidly than the solvolysis of 2-chloro-norbornane and tertiary butyl chloride.
Carbocation intermediate Substrate is primary halidebase is unhindered Substrate is primary halidebase is hindered Substrate is secondary halidebase is weak Substrate is secondary halidebase is strong Substrate is tertiary halidebase
One series of lines of the hydrogen spectrum is caused by emission of energy accompanying the fall of an electron from outer shell to the fourth shell. The lines can be calculated using the Balmer-Rydberg equation

if a gas 25.0 c occies 3.60 liters at pressure of 1.00 atm, what will be its volume at a pressure of 2.50 atm
what is the maximum amount of P4S10(444.545 g/mol) which could be formed from 17.12 g of P4 (123.895 g/mol) and 0.137 mol of S8 (256.52 g/mol).
If 42.0 g of CO and 27.0 g of H2O are placed in a 5.0 L flask with 132 g of CO2 and 6.0 g of H2 and allowed to reach quilibrium, what will the concentration of CO be when the system finally reaches equilibrium?
For a particular process that is carried out at constant pressure, q= 130 kJ and w= -20 kJ. Therefore,
Calculate the density of air at the experimental conditons identified in part A C) Calculate the mass of air in the flask before the liquid was added.
Compare in your mind 3 different liquids: pure ethanol, a 50% ethanol/water mixture and a 50 % ethanol/methanol mixture. Rank these three liquids in order of increasing Ptotal when each liquid is in equilibrium with its vapor at 25ºC.
