Lesson Question: What is the effect of pressure on the volume of a gas?
To answer this question, you used weight to
change the pressure of the gas and
measured the
resulting changes to the gas's volume.
COMPLETE
The amount of gas (in terms of moles, mass, and
molecules):

Assuming complete dissociation of the solute, how many grams of kno3 must be added to 275 ml of water to produce a solution that freezes at -14.5 c? the freezing point for pure water is 0.0 c and k_f is equal to 1.86 c/m

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
