Answer:
Solubility of the ink in the solvent
Component substances in the ink
Explanation:
Movement along the chromatography paper/fabric is determined by the solubility of the ink in the solvent and the component of the ink itself.
Chromatography is a separation technique used to separate complex mixtures.
The solution containing the mixture to be separated is spotted on a line near the end of the paper and then the paper is placed in a tank.
The solvent moves up the paper and it separates the mixtures in the spot into a number of different spots.
We can see that the solubility of the ink and component of the ink determines how they will be separated.
Answer:
Volume of chlorine solution required is around 1.2 L
Explanation:
Volume of water in the pool = 2.0*10^4 gal
1 gal = 3.79 L
Therefore, volume of water in the pool in units of Liters would be:
Density of water = 1 g/ml = 1000 g/L
The accepted concentration of chlorine = 1 g/ 10⁶ g water
Therefore amount of chlorine required to disinfect the pool water would be:
The given solution is 6.0% w/w chlorine i.e.
6.0 g chlorine in 100 g solution
Therefore, amount of solution corresponding to 74 g chlorine would be:
Density of the solution = 1 g/ml
Answer: About 10,200 Joules of heat is required to transform 80.0 g of solid benzene at 5.53°C into liquid benzene, also at 5.53°C.
Mass of Iron (Fe): 55.845Mass of Bromine (Br): 79.904
You need to multiply the mass of Br by 3 because there are 3 Bromine atoms.
(79.904)(3)+ 55.845= 239.712+55.845 = 295.557 g/mol
