Answer:
4.88 M
Explanation:
M = number moles/Volume (L)
MM AlCl3 = 133.34 g/mol
Volume = 500 mL = 0.5 L
number moles = mass/MM = 325.4/133.34 = 2.44 moles AlCl3
M = 2.44/0.5 = 4.88 M
Rf value is the ratio of the distance traveled by the solute to that of the solvent front on the paper used in chromatographic separation.
From the image it is clear the distance traveled by solvent front = 7.3 cm
Distance traveled by the component -1 of the mixture = 1.4 cm
Distance traveled by the component -2 of the mixture = 3.0 cm
Distance traveled by the component -3 of the mixture = 4.5 cm
Distance traveled by the component -4 of the mixture = 6.5 cm
Rf value of component-1 = 
Rf value of component-2 = 
Rf value of component-3 = 
Rf value of component-4 = 
b) Samples can be separated from a mixture using chromatography as the relative affinities for the compounds towards the paper (stationary phase) and the solvent(mobile phase) are different. Each component spends different amounts of time on the stationary phase depending on it chemical nature. So, the components in a mixture can be separated based on their polarities and relative degrees of adsorption on the stationary phase.
Answer:
The Monomer is Carbon
Explanation:
Carbon is the smallest unit that forms the polymer diamond
Answer:
The answer to your question is given below.
Explanation:
Potential energy is the energy stored in a body by virtue of its location. Mathematically, potential energy is expressed as:
Potential energy (P.E) = Mass(m) x Acceleration due to gravity (g) x Height (h)
P.E = mgh
Since the mass of the object is always constant and the acceleration due to gravity is also constant, it therefore means that the potential energy of an object is directly proportional to the height where the object is located.
This implies that as the height to which the object is located increases, the potential energy of the object also increases and as the height to which the object is located decreases, the potential energy of the object will also decrease.
In the diagram given above, point 1 is higher than point 4. This will cause the potential energy of the roller to be higher at point 1 than at point 4.
Answer:
True
