I think it is 20.42 g I don't know hope I've helped
Alr u see. argon is in group 8 of the periodic table, also known as noble gases. noble gases all have full shells, octect. this means that there is no chance for covalent or ionic bonding, no valence electrons available to bonding.
however, chlorine is in group 7 of the periodic table. this means to obtain a full octect shell, they will have to undergo covalent bonding to form a full octect shell.
hence, argon is more stable compared to chlorine
Answer:
Potassium iodide
Explanation:
The white solid introduced into the solution is potassium bromide. This is an ionic solid thus it quickly dissolves in water to yield a colorless solution.
When chlorine is added to this solution, the iodine is displaced since chlorine is above iodine in the electrochemical series.
When mixed with hexane, the color of the solution changes to purple.
