1.) What is the energy (in kilojoules per mole) of an FM radio wave at 93.3 MHz?
|
E=h(frequency)
E= energy h=Planks constant |
|
|
A gas bottle contains 0.650 moles of gas at 730 mm Hg pressure. If the final pressure is 1.15 atm, how many moles of gas were added to the bottle?
|
convert final pressure to torr, then multiply by number of moles then divide by moles pressure in mm Hg gives you new amount in moles. Subtract old aomount from new amount.
|
|
|
A balloon contains 0.76 mol N2, 0.18 mol O2, 0.031 mol He, and 0.026 mol H2 at 744 mm Hg. What is the partial pressure of O2?
|
Add up all numbers of moles. Put moles of designated element above to get mole ratio, then multiply by total pressure in atms.
|
|
|
How many grams of N2 gas are there in a 5.00 L cylinder at 4.00 x 103 mm Hg and 23° C?
|
PV=nRT
|
|
|
What processes occur at the triple point?
|
All 6
|
|
|
18.) Which of the following set of variables are inversely related to each other?
|
amount of gas and temperature
|
|
|
What mass (g) of NaN3 is required to provide 40.0 L of N2 at 25.0 °C and 763 torr?
|
PV=nRT with all the extra shit, than use mole ratios
|
|
|
q = mcΔT
|
Q = m*c*(delta T)
Q = heat energy m = mass c = specific heat delta t = change in temperature (= final - initial temp) |
