The molecules in a real gas have finite volumes and do exert forces on each other, thus real gases do not conform to some of the assumptions of an ideal gas as stated by the kinetic molecular theory. True or false? Answer true or false: One mole O2(g) at 0 deg C ...
Calculate the number of molecules per unit volume in an ideal gas at STP. How is average atomic mass calculated? How do I count sigma and pi bonds and how do you determine the hybridization of certain atoms? What charges an atom? How many quarks are in (a) a baryon? (b) an antiba...
How many moles of CO_{2} are produced when 3.01 * 10^{23} molecules of C_{3}H_{6} react completely in the following equation? 2C_{3}H_{6} + 9O_{2} \rightarrow 6CO_{2} + 6H_{2}O During a complete combustion of C_4H_8 How many moles of oxygen are consum...
Perkins and Nesbitt directed a beam of carbon dioxide molecules at a pool of synthetic fluorinated fluid in a vacuum. The molecules that bounced off passed through an infrared laser beam. It was found that the molecules were tumbling forward after hitting the fluid....
