Imagine that you have an ideal gas in a 8.90 L container, and that 1550 molecules of this gas collide with a square-inch area of the container at any given instant. If the volume is increased to 71.2 L at constant temperature, how many collisions will occur per square inch of this larger container?
An experiment requires 44.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder. What volume of the liquid should he use?
Rank these elements according to first ionization energy (highest to lowest) : Ne, F, O, N, C, B, Be, Li. HINT: There is a general trend for ionization energy within a period of the periodic table
A Gouy balance is used to determine the magnetic susceptibility of a substance. A strong electromagnet is placed next to the sample, which is on a balance.
A buffer contains 0.50 mol NH4^+ and 0.50 mol NH3 diluted with water to 1.0 L. How many moles of NaOH are required to increase the pH of the buffer to 10.00
A flask containing only NO2(g) at an initial pressure of 8.60 atm is allowed to reach equilibrium. Calculate the total pressure in this flask at equilibrium.
Write the reaction which occurs when BH3 encounters water. Hint: a gas is evolved and boric acid is formed. How does acetone react with BH3?
The volatile liquids A and B are confined to a piston and cylinder assembly. The pure vapor pressure of A is 165 torr, and for B is 85.1 torr. Initially only the liquid phase is present
Calculate the pre-equilibrium concentration of Fe3+(aq) in a solution made by mixing 2.8 mL of 2.010?3 M Fe(NO3)3 and 7.2 mL of 2.010?3 M NaSCN. Assume the final volume is 10.0 mL.
Use the concentrations given below for the concentrated chemcal molarities and write out your calculations to obtain the volume of each stock solution needed to obtain 30.00 L of a 6.00 M
Calculate the pH of a buffer solution that is 0.200 M HC2H3O2 and 0.100 M in NaC2H3O2. Calculate the pH of the buffer that reults from mixing
A sample of solid aluminum with a mass of 1.75 Kg is cooled at constant pressure from 300 to 265 K. Calculate the entropy change. Cp,m = 24.35 J/(K mol).
a 35.00 ml solution of 0.2500 m hf is titrated with a standardized 0.1356 m solution of naoh at 25 c.a what is the ph
