Answer:
CH₄
Explanation:
According to Graham's law, <em>the rate of effusion of a gas (r) is inversely proportional to the square root of its molar mass (M)</em>.
Let's consider the following gases and their molar masses.
A) NH₃ 17.03 g/mol
B) CH₄ 16.04 g/mol
C) Ar 39.95 g/mol
D) HBr 80.91 g/mol
E) HCl 36.46 g/mol
Of these gases, CH₄ will have the greatest rate of effusion at a given temperature because it has the lowest molar mass.
Answer:
I would go for number 5 . It sounds more logical to me.

Answer:
the number of neutrons in the nucleus
Explanation:
The mass number 205 is the total number of protons and neutrons in the nucleus. Lead has 82 protons, so a mass number of 205 indicates a nucleus with 123 neutrons.
Similarly, the mass number 208 indicates a lead nucleus with 126 neutrons.
The difference in atomic structure is the difference in the number of neutrons in the nucleus.
