Answer:
The aqueous solution of 
therefore would be "strongly basic."
Explanation:
Strongly basic because the is completely an ionic compound. These compound can be 100% splitted into metal ions and hydroxide ion when used in the aqueous solution. Each moles dissolves which can give rise to mole of hydrogen ions when used in the solution. Whereas strong bases are not soluble in water as well. in the presence of water equilibrium can also be achieved. A strong base has the capability which can just remove the proton from the molecule.
I think it’s A good luck on the answer if it’s not but I’m pretty sure it’s A .
You have a. 3, b. 2, e. 6, f. 3, i. 1
Answer:
The mixture 1/ must be homogeneous where there is one or more dissolved salts; 2/ should only contain one liquid component.
Explanation:
This method drives off the liquid components from the solid components. The process typically involves heating the mixture until no more liquid remains. Prior to using this method, the mixture should only contain one liquid component, unless it is not important to isolate the liquid components. This is because all liquid components will evaporate over time. This method is suitable to separate a soluble solid from a liquid.
Note : In many parts of the world, table salt is obtained from the evaporation of sea water. The heat for the process comes from the sun.

Answer:
We are given:
V(i) = 0.3 L V(f) = 0.36 L
P(i) = x pa P(f) = 400 pa
T(i) = T(f) = 293 k
Using the gas formula:
PV = nRT
Since n , R and T are constant,
PV = k (where k is a constant)
Hence we can say that:
P(i) * V(i) = P(f) * V(f)
x * 0.3 = 0.36 * 400
x = 14.4/0.3
x = 480 pascals
Hence the initial pressure is 480 pascals
Converting to Kpa, we have to divide by 1000
Initial pressure (Kpa) = 0.48
