The answer would be C because I did the test and I got 1 question wrong and made an 90% .
Argon has 8 valence electrons. It's atomic number is 18, therefore, in the first shell there are 2, the second has 8 and the third also has eight.
There are 2.06 x 10²⁴ atoms
<h3>Further explanation
</h3>
The mole is the number of particles (atoms, molecules, ions)contained in a substance
1 mol = 6.02.10²³ particles
Moles can also be determined from the amount of substance mass and its molar mass

Explanation:

<em>According to <u>le ch</u></em><em><u>-</u></em><em><u>atelier'</u></em><em><u>s</u></em><em><u> </u></em><em><u>principle</u> when a chemical reaction at equilibrium subjected to any stress, then the equilibrium shifts in that direction in which effect of stress is reduced.</em>
When we would add more number of carbon in above reaction then rate of forward reaction will increase to attain the equilibrium again.
