Step by step explanation:
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:
0.3 mol
Explanation:
Assuming HCl is in excess and Zn is the limiting reagent,
from the balanced equation, we can see the mole ratio of Zn:H2 = 1:1,
which means, each mole of zinc reacted gives 1 mole of H2.
So, if 0.30 mol Zn is added, the no. of moles of H2 produced will also be 0.3 mol, since the ratio is 1:1.
300 degrees Kelvin = 300 - 273 = 27 degrees Celsius.
So what you need to do is find out how many degrees Fahrenheit that is.
F = 9/5(27) + 32
F = 48.6 + 32
F = 80.6
You are at 55oF. You need to go from 55 to 80.6 or 25.6 degrees F.
