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
A cube has a volume of 8.0cm (to the 3rd power) and a mass of 21.6 grams. The density of the cube, in grams per cubic centimeter, is best expressed as
3H2+N2=How many grams of NH3 can be produced from 3.91g of N2?
Determine the concentration of hemoglobin solution knowing that its absorbance is 0.65. The pathlength is 1 cm and the extinction coefficient is 3.9 x 105 M-1cm-1.
A rigid vessel contains 10 kg of steam. the steam is initially at 10 bar and 300 C. After a period of time the pressure in the vessel is reduced to 1 bar due to heat transfer with the surroundings.
Using the given reduction potential determine what is the voltage for these given electrochemical cell
What is the most common oxidation state of the chalcogens compared to the halogens? What is an explanation for the difference?
Would applying a high pressure stabilize the CsCl form, or the NaCl form of this compound? (hint: calculate the volume per formula unit)
H2S and H2O have similar structures and their cenertal atoms belong to the same group. Yet H2S is a gas at room temperature and H2O is a liquid. Use bonding principles to explain why this is.
For the reaction, A = B + C, the rate law is k[A]. If it takes 80.0 seconds for 70.0% of a 10.0 gram sample of A to be transformed into products, what is the value of the rate constant.
construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
determine the partial pressure and the total pressure in a 2.50 L vessel containing the following mixture of gases at 17.8 degrees celsius
