4% starch solution will decrease in volume.
This is because the less starch concentration, the more water molecules exists. Since 4% is less than 10%, so the 4% will contain more water. Water molecules tend to flow from a region of higher water potential to a region of lower water potential through the semi permeable membrane in osmosis. Therefore, since the 4% contains more water, the water there will flow away from the 4% and to the 10% one in order to reach equilibrium.
Answer:
For carbon-12 is: 6c^12
For carbon-13 is: 6c^13
For carbon-14 is 6c^14
Note: the number 6 is the lower subscript in all three.
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:
.
I think it's called a Halide or a halogen
