Answer:
PH is a logarithmic scale it means that 1 increase or decrease in PH changes concentration tenfold
PH 3 is 10 times more acidic than PH 4
Explanation:
3. A full octet (8 electrons) is needed to be stable. So if the atom gets 3 more atoms it will be stable.
Effusion rate, R, is inversely proportional to the square root of the molar mass, M:
R α 1 / √M
Let Ra be the effusion rate of a gas with molar mass Ma and Rb the efussion rate of a gas with molar mass Mb, then:
Ra / Rb = √ [Mb / Ma]
You know Ra / Rb = 1.82 and Ma = molar mass of N2 = 28.02 g/mol
=> Mb = [Ra / Rb]^2 * Ma = (1.82)^2 * 28.02 g/mol = 92.81 g/mol
Answer: 92.81 g/mol
