In the simulation, set the temperature of the sample gas to 304 . Click on the "Run" button and observe how the number of moles of the gas varies with an increase in the gas's volume. Then, click on the "Reset" button, set the temperature of the sample gas to 504 , and click on the "Run" button again.
Observe the graph produced in the simulation and select the correct options listed below.
Which of the following are apply?
1.The volume of the sample gas increases linearly with the number of moles.
2.The volume of the gas doubles when the number of moles of the gas is doubled at the same temperature.
3.Volume is inversely proportional to the number of moles of the gas.
4.The pressure of the sample gas increases with an increase in volume.
Describe the bonding in SeO2 in valence bond terms. Note whether or not there is delocalized bonding and explain how molecular orbital theory can be useful here.
Calculate the total heat in joules needed to convert 25.00 g of ice at -3.50 degrees c to liquid water at 0.250 degrees c.
Free radicals are important in many environmentally significant reactions. For example, photochemical smog, which forms as a result of the actions of sunlight on air pollutants, is formed in part by the following two steps.
And, of course, ammonia is a base so there will be some NH4+ in solution also. Assume that the concentration of unprotonated NH3 is 0.040 M. What fraction of the cadmium ions are in the form of Cd2+

What is the enthalpy change for the neutralization reaction of 1 mol of CsOH in kJ?
The dimerization of ClO is second order in ClO. Use the following data to determine the value of k and the half-life at 350 K
As a bromine molecule approaches perpendicular to the negatively charged pi cloud of the carbon-carbon double bond, its bonding electrons are repelled away from the bromine atom nearer the double bond
A 29.0-g sample of ice at -11.0°C is mixed with 113.0 g of water at 71.0°C. Calculate the final temperature of the mixture assuming no heat loss to the surroundings.
Gilman reagents will react with alkyl halides to form carbon-carbon bonds. Outline a synthesis of Ph2CuLi and use it to make butylbenzene isomer free. What other way can you make butylbenzene isomer free?
boiling water at sea level is hotter than boiling water in the mountains. Water used to sterilize surgical equipment is heated to 120 degrees C at 2.0 atm in an autoclave.
