Fluorine gas effuses 1.37 times faster than chlorine gas
calculation
Rate of F2/rate of Cl2 =√ molar mass Cl2 / molar mass F2
rate of F2/Rate of Cl2 = √1.868
rate of F2/rate of Cl2 =√ 71/38 = 1.37 times faster than chlorine
A) Cl- ion
B) These energies are equal for all forms of the same element
Explanation:
The ionization energy for a chlorine atom is equal in magnitude to the electron affinity of Cl⁻ ion because these energies are equal for all forms of the same element.
- Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase.
- Ionization energy is the amount of energy required for the removal of an electron in atom or ion.
- Here the energy released when an electron is added to the Cl atom(electron affinity) to form a chlorine ion is the same energy that would be required to remove the added electron from the ion to form an atom(electronegativity).
- Here we find out that both energies are the same for the atom of Cl that is gaining electron and for the ion in which electron is being removed.

Answer:
69.7 amu
Explanation:
To get the atomic mass of Gallium, we use the relative abundance of the isotopes.
This is used as follows:
[60.11/100 * 68.9256] + [39.89/100 * 70.9247]
= 41.43117816 + 28.29186283 = 69.72304093 amu
It’s B since it has chloroplasts
