‘Chromatography’ is an analytical technique commonly used for separating a mixture of chemical substances into its individual components, so that the individual components can be thoroughly analyzed. There are many types of chromatography e.g., liquid chromatography, gas chromatography, ion-exchange chromatography, affinity chromatography, but all of these employ the same basic principles.

Chromatography is a separation technique that every organic chemist and biochemist is familiar with. I, myself, being an organic chemist, have routinely carried out chromatographic separations of a variety of mixture of compounds in the lab. In fact, I was leafing through my research slides and came across a pictorial representation of an actual chromatographic separation that I had carried out in the lab. I guess that picture would be a good starting point for this tutorial!

Let me first explain what I was trying to do here. I had two reactants ‘A’ and ‘B’. I let them react with each other, under certain reaction conditions, to form a product ‘C’. After the reaction was complete, I ended up with a reaction mixture that contained unreacted A, unreacted B and my desired product C. Now my task was to separate out A, B and C to isolate and analyze pure product C.

The drift velocity of electrons in germanium at room temperature, when the magnitude of the electric field is 200 V/m, is 76 m/s.

Given,

μ (mobility of electrons) = 0.38 m²/V·s

E (electric field strength) = 200 V/m

The drifts velocity of electrons in germanium at room temperature: v = μ × E

where:

v_d is the drift velocity of electrons

μ is the mobility of electrons

E is the electric field strength

v_d = 0.38 m²/V·s × 200 V/m

v_d = 76 m/s

The aqueous solutions can be arranged in increasing boiling point order as follows: 0.050m Al(ClO4)3 < 0.110m K2CO3 < 0.300m C6H12O6.

The boiling point of a solution is influenced by the concentration of solute particles in the solution. The greater the concentration of solute particles, the higher the boiling point. In this case, we are comparing the boiling points of three different aqueous solutions.

The solution with the lowest boiling point is 0.050m Al(ClO4)3. This is because Al(ClO4)3 is an ionic compound that dissociates into multiple ions in water, thereby increasing the number of solute particles. Higher concentration of solute particles raises the boiling point.

The solution with the next higher boiling point is 0.110m K2CO3. K2CO3 is also an ionic compound and dissociates into two ions in water. Although the concentration is higher compared to Al(ClO4)3, it is lower than that of C6H12O6.

The solution with the highest boiling point is 0.300m C6H12O6. C6H12O6, which is glucose, is a molecular compound and does not dissociate into ions in water. Therefore, it has the lowest concentration of solute particles among the given solutions, resulting in the lowest boiling point.

Hence, the correct order of increasing boiling points is 0.050m Al(ClO4)3 < 0.110m K2CO3 < 0.300m C6H12O6.

The reactants in each of the gizmo emission reactions depend on the specific reaction being referred to.

Without further information, it is not possible to provide a single line direct answer. However, in general, gizmo emission reactions involve the release of particles or energy from an atomic nucleus.

In terms of the graph of nuclear stability, the reactants for gizmo emission reactions are typically located above the belt of stability.

These reactions involve the emission of particles such as alpha particles (helium nuclei), beta particles (electrons or positrons), or gamma rays (high-energy photons) from unstable nuclei.

Unstable nuclei are located above the belt of stability, which represents the region of stable isotopes.

The emission reactions occur as a means for the unstable nuclei to attain greater stability by reducing excess energy or achieving a more favorable neutron-to-proton ratio.

It's important to note that the specific reactants and their positions on the graph in relation to the belt of stability can vary depending on the type of gizmo emission reaction being considered.

The maximum number of moles of gas X in the balloon at 37°C is 0.127 mol, and the maximum temperature so that the balloon doesn't burst with 0.0800 mol of gas X is 523 K.

To determine the maximum number of moles of gas X in the balloon at 37°C, we need to use the ideal gas law, 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. At STP, the pressure is 1 atm, and the temperature is 273 K.

First, we can use the maximum volume of the balloon to calculate the maximum number of moles of gas X that can be in the balloon without it bursting. Assuming the pressure is constant, we can rearrange the ideal gas law to solve for n:

n = PV/RT

n = (1 atm)(2.50 L)/(0.0821 L·atm/mol·K)(273 K)

n = 0.114 mol

So the maximum number of moles of gas X that can be in the balloon without it bursting is 0.114 mol.

Next, we can use the maximum number of moles of gas X to determine the maximum temperature so that the balloon doesn't burst. Again using the ideal gas law, we can solve for the temperature:

T = PV/nR

T = (1 atm)(2.50 L)/(0.114 mol)(0.0821 L·atm/mol·K)

T = 851 K

However, this temperature is too high for the balloon to withstand, so we need to adjust it. We can use the maximum number of moles of gas X that we calculated earlier (0.114 mol) and the given number of moles of gas X (0.0800 mol) to determine the maximum temperature that the balloon can withstand without bursting:

T = (0.0800 mol)(0.0821 L·atm/mol·K)(2.50 L)/(0.114 mol)(1 atm)

T = 523 K So the maximum temperature that the balloon can withstand without bursting is 523 K.

The glycosidic bond forms between the carbon atom on the glucose molecule and the nitrogen atom present on the nitrogenous base. A diagram has been attached to show this particular bond. There is also a phosphate molecule bonded on the sugar molecule at the other end.

The part of the atom that is most critical for creating chemical bonds is electrons. Option C is correct.

Electrons are the subatomic particles that play a primary role in the formation of chemical bonds. Chemical bonds are interactions between atoms that hold them together in compounds. These bonds are a result of the sharing, transferring, or redistribution of electrons between atoms.

In a chemical reaction, atoms can gain, lose, or share electrons to achieve a more stable electron configuration. The outermost shell of an atom, known as the valence shell, is particularly important in bonding because it determines the atom's reactivity and ability to form bonds.

By gaining, losing, or sharing electrons, atoms can achieve a full valence shell, which typically consists of eight electrons (the octet rule). This stable electron configuration allows atoms to have a lower potential energy and increased stability.

The interactions between electrons in the valence shells of different atoms determine the type of chemical bond formed. Covalent bonds involve the sharing of electrons between atoms, while ionic bonds involve the transfer of electrons from one atom to another.

Hence, C. is the correct option.

If you had a solution containing a mixture of magnesium, strontium, and barium, then we could separate these three elements using hydrogen sulphide, chromic acid and sulphuric acid.

To separate three elements from the solution, first we need to remove the magnesium element by adding hydrogen sulphide(H₂S) in the solution. It forms magnesium sulphide(MgS) as a precipitate and remaining ions are used for further separation.

To separate the barium element, we need to add chromic acid in the solution, which precipitate the barium chromate(BaCrO₄) from the solution.

In the remaining solution of strontium, we need to add sulphuric acid, which precipitates out the strontium sulphate(SrSO₄) as a product.

Decomposition reaction, also known as analysis or dissociation, is a type of chemical reaction in which a compound breaks down into simpler substances or elements. In this reaction, a single reactant undergoes a chemical change and produces two or more products.

The decomposition reaction can be represented by the general equation:

AB → A + B

Where AB is the reactant, and A and B are the products. The reactant AB is usually a compound, and it breaks down into its constituent elements or simpler compounds.

There are different types of decomposition reactions, including:

Thermal decomposition: It occurs when a compound is heated, resulting in its decomposition into simpler substances. For example, the thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2):

CaCO3 → CaO + CO2

Electrolytic decomposition: It takes place when an electric current is passed through an electrolyte, causing it to break down into its component ions. For instance, the electrolysis of water (H2O) leads to the decomposition into hydrogen gas (H2) and oxygen gas (O2):

2H2O → 2H2 + O2

Photochemical decomposition: It occurs when a compound undergoes decomposition due to exposure to light energy. Chlorine gas (Cl2) can decompose into chlorine atoms (Cl) under the influence of light:

Cl2 → 2Cl

These are just a few examples of decomposition reactions. They are important in various chemical processes and are used in industries, laboratory experiments, and natural phenomena. By understanding and controlling decomposition reactions, scientists can gain insights into the behavior of different compounds and develop practical applications in fields such as chemistry, materials science, and environmental science.
