a) A cylindrical gas chamber at a constant temperature has a piston at one end that can be used to compress or expand the gas. If the gas is initially at 1.22 atm when the volume is 7.26 L, what will the pressure be if the volume is adjusted to 3.60 L?
b) A sample of argon gas at a constant pressure of 715 mmHg and a temperature of 26°C occupies a volume of 8.97 L. If the gas is heated to a temperature of 71°C, what will be the volume of the gas sample?
c) A sample of krypton gas occupies a volume of 6.68 L at 64 °C and 361 torr. If the volume of the gas sample increases to 8.99 L while its temperature increases to 114 °C, what will be the resulting gas pressure in torr?
d) If 3.3 grams of gas occupies a volume of 3.0 L at 520 mmHg and 151 K, what is the gram/molecular weight (gram/mole) of the sample?
what is the presentage compostition of both of the components, which is the limiting reagent (if there is) and what is the theoretical yeild of each of them.
In an electron microscope the electrons generate the image. For one of the scanning electron microscopes in our Central Analytical Facility, the electrons are accelerated to have a kinetic energy of 200,000 eV.
for the reaction Mg+2HCl yeilds H2+MgCl2, calculate the percentage yield of magnesium chloride if 100.g of magnesium react with excess hydrochloric acid to yield 330.g of magnesium cholride.
Solve for the total moles, then the total pressure of the mixture using the Ideal Gas Law. Next find the mole fraction of Argon and solve for partial pressure of Argon.
