Answer:
0.6 Molar
Explanation:
According to the Question,
In 500 mL of water ,
0.2 mol sample of MgCl is present and 0.1 mol of KCl is present.
Thus ,
Concentration of Cl anion in the solution will be the sum of Cl anion concentration from MgCl and KCl.
From MgCl , 0.2 mol of Cl anion will come and 0.1 mol of KCl anion will come ,
Thus , 0.3 mol of Cl anion will come totally .
So, Cl anion concentration will be = 0.6 M
1. Exothermic, because it’s giving off heat
2. Exothermic, because it’s giving off heat
3. Endothermic, because it’s losing heat
Answer:
7.25 x 10^47
Explanation:
1.204 x 10^24 moles*6.022 x 10^23 avogadro's number= 7.25 x 10^

Water vapor is the gaseous form of water in temperatures above 100 degrees Celsius (the boiling point of water). Once the temperature goes below 100 degrees Celsius, then water vapor reverts back to its liquid form and the process is called condensation. In extremes of temperatures such that when temperature goes below 0 degrees Celsius (the freezing point of water), water vapor can crystallize and form ice without condensing back to water first. This process is called deposition.
