Q

Physical characteristics of gas

A
  • assume volume and shape of their containers
  • will mix evenly and completely when confined in the same container
  • gases have much lower density than liquids and solids

Q

Pressure formula

A

MolesxRxTemp in Kelvin/Volume

17
Q

Before and after pressure formula

A

P1 x V1 / n1 x T1 = P2 x V2/n2 x T2

18
Q

Density formula

A

m/V = P x M / R x T

m = mass in grams
M = Molar mass of gas
19
Q

Molar mass of gas formula

A

M = d x R x T / P

20
Q

Gas diffusion

A

Gradual mixing of gases by virtue of their kinetic properties

21
Q

Gas effusion

A

Gas under pressure escapes from one compartment of a container to another by passing through a small opening

22
Q

Convert torr to atm

A

Divide torr given by 760 torr to get pressure in atm

23
Q

A

Multiply moles given by 22.4 liters

27
Q

Convert torr to atm

A

Divide torr given by 760 torr to get atm for Pressure

28
Q

gas stoichiometry

A

Amount of reactant to moles of reactant to moles of product to amount of product
