Answer:
of the stock solution would be required.
Explanation:
Assume that a solution of volume 
contains a solute with a concentration of 
. The quantity 
of that solute in this solution would be:
.
For the solution that needs to be prepared, 
. The volume of this solution is 
. Calculate the quantity of the solute (magnesium chloride) in the required solution:
.
Rearrange the equation to find an expression of volume , given the concentration and quantity of the solute:
.
Concentration of the solute in the stock solution: 
.
Quantity of the solute required: 
.
Calculate the volume of the stock solution that would contain the required of the magnesium chloride solute:
.
The ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.
<u>Explanation</u>:
- This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.
- Here we see the chef described that the ingredient's molecules are moving in place – solid.
- On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.
Answer:
unbalanced
Explanation:
as the atoms on the one side do not equal to the atoms on the other sides
