Answers
Suppose you used a plate coated with silica gel, with propanone, CHBCOCH3_ as the solvent for thin layer chromatography, the description and explanation on what the chromatogram would probably look like is given below.
What will the chromatogram look like?In thin layer chromatography (TLC), compounds are separated based on their interactions with the stationary phase (in this case, the silica gel coating on the plate) and the mobile phase (in this case, propanone). Compounds that have stronger interactions with the stationary phase will travel more slowly up the plate, while those with weaker interactions will travel more quickly.
Given the information provided, it is very likely that the chromatogram would show three distinct spots, corresponding to compounds P, Q, and R. Compound P, which can form strong hydrogen bonds, is likely to have a strong interaction with the silica gel stationary phase and will therefore travel more slowly up the plate.
Compound Q, which can also form hydrogen bonds but not as strongly as P, is likely to have a weaker interaction with the stationary phase and will therefore travel more quickly. Compound R, which relies on dispersion forces and dipole-dipole interactions for its intermolecular attractions, is likely to have a weaker interaction with the stationary phase compared to compounds P and Q and will therefore travel even more quickly up the plate.
Therefore, the chromatogram is likely to show compound P at the bottom, followed by compound Q above it, and compound R at the top. This arrangement reflects the relative strengths of the interactions between each compound and the stationary phase.

A. The charge of the unknown particles is positive.
B. The charge of the unknown particles is negative.
C. The charge of the unknown particles is neutral.
Answers
In the given statements the second statement (b) is true. The true statement is result of cathode Ray tube experiment. The charge of the unknown particles is negative.
Cathode Ray tube experiment:
J.J Thomson designed a partially evacuated glass tube. That is, all air was exhausted from the building. A high voltage was then applied across the tube between the two electrodes. He observed a flow (jet) of particles from a negatively charged electrode (cathode) to a positively charged electrode (anode). This beam is called a cathode ray and is called a cathode ray tube throughout its construction.
Experimental Procedure:
apparatus is set up by providing a high voltage source and evacuating air to maintain a low pressure in the tube.
A high voltage is applied to two metal strips to ionize the air and make it an electrical conductor. As soon as the circuit is closed, current begins to flow. A dipole was set as an accessory in the experiment to determine the composition of the beam produced by applying a high voltage to thetube.
anodes and cathodes were held on either side of the discharge beam. When the dipole was applied, the beam was repelled from the negative pole and deflected towards the positive pole.This was further confirmed by placing the phosphor at the edge of the discharge beam. It glows when hit by the discharge beam.
Results : After the conclusion of testing, J.J. Thomson concluded that light rays are essentially negatively charged particles that exist or travel with a set of positive charges. This theory further helped physicists understand the structure of the atom. And an important observation he made was that the properties of cathode rays or electrons do not depend on the material of the electrodes or the type of gas present in the cathode ray tube.
The number of electrons distributed outside the nucleus is It is the same as the number of positively charged protons in the nucleus. This explains the electroneutrality of the whole atom.

What is the molar mass of Cu(C104)2?
Answers
Cu(C104)2 is a complex ion made up of copper (Cu) and a large organic molecule known as a porphyrin. The porphyrin molecule contains four nitrogen atoms, four carbon atoms, and eight hydrogen atoms.
The atomic weight of copper is 63.55 g/mol, the atomic weight of carbon is 12.01 g/mol, and the atomic weight of hydrogen is 1.01 g/mol.
To find the molar mass of Cu(C104)2, we need to add up the atomic weights of all the atoms in the compound:
Molar mass = (1 mol Cu * 63.55 g/mol Cu) + (4 mol C * 12.01 g/mol C) + (8 mol H * 1.01 g/mol H) + (4 mol N * 14.01 g/mol N)
This simplifies to:
Molar mass = 63.55 g/mol + 48.04 g/mol + 8.08 g/mol + 56.04 g/mol
The molar mass of Cu(C104)2 is therefore 175.71 g/mol.

Answers
Substituting the given values, we have (0.5 L) / (220 + 273.15 K) = V₂ / (313.15 K).Solving for V₂, we get V₂ = (0.5 L) * (313.15 K) / (220 + 273.15 K).
Calculating this expression, the volume of the balloon when fully cooled by your refrigerator would be approximately 0.38 liters when rounded to two decimal places.To convert Celsius to Kelvin, we need to add 273.15 to the Celsius temperature. Therefore, the temperature inside your refrigerator of 40 degrees Celsius is equivalent to 313.15 Kelvin.Now, let's consider the ideal gas law, which states that PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.Since the number of moles and pressure remain constant, we can write the equation as V₁/T₁ = V₂/T₂, where V₁ is the initial volume of the balloon, T₁ is the initial temperature, V₂ is the final volume, and T₂ is the final temperature.

Answers
The kinetic energy of a 23.2-g object moving at a speed of 98.7 m/s is 113.30 J. Option D
The kinetic energy of an object can be calculated using the formula: KE = (1/2)mv^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity or speed of the object.
Given:
Mass (m) = 23.2 g = 0.0232 kg
Speed (v) = 98.7 m/s
Substituting these values into the formula, we can calculate the kinetic energy:
KE = (1/2)(0.0232 kg)(98.7 m/s)^2
KE = (1/2)(0.0232 kg)(9756.09 m^2/s^2)
KE ≈ 113.30 J
Therefore, the kinetic energy of a 23.2-g object moving at a speed of 98.7 m/s is approximately 113.30 J.
It's worth noting that the question is repeated twice, but the answer remains the same. The kinetic energy of the object is determined by its mass and speed, and both calculations yield the same result. Option D

The order of reaction is defined as the power to which the concentration of the reactants are raised in the rate equation of the reaction.
The order of reaction can be used to determine how a particular reactant affects the reaction. In order to find the order of a reaction with respect to a particular reactant, the concentration of the reactant is changed while keeping the concentration of other reactants constant. The rate of reaction is then measured and compared with the rate of reaction when the concentration of the reactant is not changed.The order of reaction with respect to a reactant can be determined using the following method:First, select a reactant whose order needs to be determined and change its concentration while keeping the concentration of other reactants constant. For example, if we want to find the order of reaction with respect to reactant A, we will change the concentration of A and keep the concentration of reactant B constant.Second, measure the rate of reaction at different concentrations of the reactant A. The rate of reaction can be measured by any suitable method such as change in color, pH, or by measuring the amount of product formed with time. A graph is plotted with rate of reaction on the y-axis and concentration of reactant A on the x-axis. The graph should be a straight line.Third, if the graph is a straight line passing through the origin, the order of reaction with respect to reactant A is one. If the graph is a straight line but does not pass through the origin, the order of reaction with respect to reactant A is two.

How many moles of water were lost if the amount of water lost was 0.369 grams? Do not include units and assume three significant figures in all numbers. Be sure to include the zero before the decimal if the number is less than one.
Answers
0.0205 moles of water were lost if the amount of water lost was 0.369 grams. The given answer is in three significant figures with including zero before the decimal.
To find the number of moles of water lost, we need to know the molar mass of water (H2O).
Molar mass is the sum of the atomic masses of all the atoms present in a molecule.
Since the molecule of water contains two atoms of hydrogen and one atom of oxygen, the molar mass of water is given by the sum of the atomic masses of two hydrogen atoms and one oxygen atom, which is: 2(1.008 g/mol) + 1(15.999 g/mol) = 18.015 g/mol
Therefore, one mole of water has a mass of 18.015 g.
