Answer 2

:3 thanks

Answer 3

anytime

Answer 4

Which statement about gas effusion is true?
A) lighter gases effuse faster than heavier gases
B) lighter gases effuse slower then heavier gases
C) effusion is not related to the molar mass of gases
D) light and heavy gases effuse at the same rate

Answer 5

Answer 6

a

Answer 7

Graham's Law,
the rate of effusion of a gas is inversely proportional to the square root of its molar mass.
which means means that lighter gases will effuse faster than heavier ones

Answer 8

off the top of my head

\[\frac{ r_{1} }{ r_{2} } = \sqrt{\frac{ b }{ a }}\]

molar mass of gas B
molar mass of gas A
