Write the symbols for the cation and the anion: Mg and Cl. Determine the charge on the cation and anion. If the cation has a Roman numeral after it, that is the charge on that cation. Cations receive Roman numerals when they can take more than one ionicform.

Answer:</h3>
Chlorine gas (Cl₂)
<h3>
Explanation:</h3>
- According to the Graham's law of diffusion, the diffusion rate of a gas is inversely proportional to the square root of its density or molar mass.
- Therefore, a lighter gas will diffuse faster at a given temperature compared to a heavy gas.
- Consequently, the heavier a gas is then the denser it is and the slower it diffuses at a given temperature and vice versa.
In this case we are given gases, CI₂
, H₂,He and Ne.
- We are required to identify the gas that will diffuse at the slowest rate.
- In other words we are required to determine the heaviest gas.
Looking at the molar mass of the gases given;
Cl₂- 70.91 g/mol
H₂- 2.02 g/mol
He - 4.00 g/mol
Ne- 20.18 g/mol
Therefore, chlorine gas is the heaviest and thus will diffuse at the slowest rate among the choices given.
<u>Answer:</u> The isotope produced after the transmutation process of Cf-249 and C-12 is 
<u>Explanation:</u>
Transmutation is defined as the process where one chemical isotope gets converted to another chemical isotope. The number of protons or neutrons in the isotope gets changed.
The chemical equation for the reaction of Californium-249 nucleus with Carbon-12 nucleus follows:
In a nuclear reaction, the total mass and total atomic number remains the same.
<u>To calculate A:</u>
Total mass on reactant side = total mass on product side
249 + 12 = A + 4
A = 257
<u>To calculate Z:</u>
Total atomic number on reactant side = total atomic number on product side
98 + 6 = Z + 0
Z = 104
Hence, the isotope produced after the transmutation process of Cf-249 and C-12 is
