Insoluble means that a substance does not dissociate in another, like mixing water and oil.
In an unsaturated solution, the solute does dissociate into solution but there is more "room" in the solution to hold more. Say if you have an amount of water that can dissolve 20g of salt but you only have 15g dissolved in it, that solution is unsaturated.
Answer:
0.1795 M
Explanation:
From the given information:
The equation is:
From the above equation, the reaction will go to completion due to the strong base:
At the equivalence point, moles of acid (HF) will be equal to moles of base (KOH)
Thus. since moles of HF = moles of KOH
Then; 0.020 × 0.393 M = 0.02379 × (x) M
(x) M = 
(x) = 0.3304 M
Thus, the molarity of KOH = 0.3304 M
Using the balanced neutralization reaction;
moles of HF = moles of KOH = moles of conjugate base = 0.00786 mol
∴
Volume = 0.020 L + 0.02379 L
Volume = 0.04379 L
Volume of the solution = 0.04379 L
Therefore; Molarity = 
Molarity = 
Molarity = 0.17949 mol/L
= 0.1795 M
I believe the statement is true. The heat transfer involved here is called conduction. It is one type of heat transfer where it caused by the collisions of the particles in a certain body. As the you add heat to the object, the kinetic energy of the molecules increases therefore more collisions could happen which would mean energy is dissipated or transferred from molecule to molecule.<span />
Greenhouse gases are the gases in the atmosphere that keep the air in the atmosphere. It also traps the sun's sunlight. Since the heat is trapped in here, it would contribute to higher temperatures. *Have a nice day!!*
