To all the boys my age out there my name is Tytianna I'm sorry I'm not depressed I'm just lonely and I'm sorry I was so mean to yall

Which of these expressions are correct variations of the combined gas law? p1v1t2 = p2v2t1 both

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?

1. list the number of drops of titrant needed to produce a color change for sample a and sample b. list the actual volume of titrant needed to produce a color change for sample a and sample b.
