32
Q

What is the density formula?

A

n(MM)/V=d=P(MM)/RT

33
Q

When you have only Pressure and Volume what is the formula and relationship?

A

V = constant x 1/P

Pressure increases, Volume decreases

34
Q

When you have only Temperature and Volume what is the formula and relationship?

A

V = constant x T

Volume increases, Temperature increases

35
Q

When you have only Moles and Volume what is the formula and relationship?

A

V = constant x n

Volume increases, Moles increase

36
Q

When give Pressure and Volume how are they proportional?

A

P1V1 = P2V2

37
Q

When given Temperature and Volume how are they proportional?

A

V1/T1 = V2/T2

38
Q

When given Moles and Volume how are they proportional?

A

V1/n1 = V2/n2

39
Q

What are the two formulas for Partial Pressure?

A 
Pt = ntRT/v
P1 = (n1/nt)Pt = X1Pt
40
Q

What is the relationship or rms and MM?

A

the lower the MM, the higher (faster) rms

41
Q

What is the formula for rms?

A

u = sqrt(3RT/MM)

42
Q

What is a sigma bond?

A

is a bond formed between atoms,
which has the highest electron density along the
bond axis

43
Q

What is a pi bond?

A

is bond formed by a side to side

overlap of the 2p orbitals

44
Q

What does a double bond made from?

A

1 sigma bond and 1 pi bond

45
Q

Two domains is what level of hybridization?

A

2sp

46
Q

Three domains is what level of hybridization?
