Explanation:

The mixture of 4-chloroaniline, benzoic acid and 1,4-dibromobenzene is separated based on their different solubility properties.

4-nitroaniline is basic and is first extracted using an acid, hydrochloric acid.

Benzoic acid is an acid, hence is extracted using a base, using either sodium hydrogen carbonate or sodium hydroxide.

1,4-dibromobenzene is neutral and is extracted from an organic solvent by evaporation using its property of solubility in an organic solvent.

In the flow chart illustrating the separation process, first the mixture of organic compounds is dissolved in ether, an organic solvent and then placed in a s eparatory funnel.

Then, the basic amine compound,  4-chloroaniline is removed from the organic layer into an aqueous layer by adding an inorganic acid, HCl. The aqueous lower layer is drained into a conical flask. The 4-chloroaniline is then precipitated out of solution by adding concentrated NaOH dropwise.

The organic acidic, benzoic acid is then extracted from the organic layer by adding an inorganic base, sodium hydrogen carbonate. The lower aqueous layer is drained into another flask. Benzoic acid is then precipitated out of solution by adding a concentrated solution of HCL.

The neutral 1,4-dibromobenzene is then obtained by evaporation of the organic solvent

Answer:

greater, two, three

Explanation:

Cations are positively charged ions. In an octahedral complex, the d orbitals undergo greater repulsion and split into 2 high, and 3, low energy groups.

An octahedral complex is a molecular geometry of a compound in which the six atoms are aligned in symmetry around the central metal atom.

The molecule has eight faces and hence is called octa. The two d orbitals present in the structure experience greater repulsive force compared to the three orbitals of d orbit.

Therefore, the d orbit of the molecule has two high-energy orbitals while having three lower energy molecules.

Answer:

Option 1. NO

Explanation:

The balanced equation for the reaction is given below below:

4NH₃ + 6NO —> 5N₂ + 6H₂O

From the balanced equation above,

4 moles of NH₃ reacted with 6 moles of NO.

Finally, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

4 moles of NH₃ reacted with 6 moles of NO.

Therefore, 1.24 moles of NH₃ will react with = (1.24 × 6)/4 = 1.86 moles of NO

From the calculation made above, we can see that a higher amount of NO (i.e 1.86 moles) than what was given (i.e 1.79 moles) is needed to react completely with 1.24 moles of NH₃.

Therefore, NO is the limiting reactant and NH₃ is the excess reactant.

Thus, the 1st option gives the correct answer to the question

Answer:

1. NO .

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to identify the limiting reactant by simply calculating the moles of any product, say N2, via the moles of each reactant and including the corresponding mole ratio (4:5 and 6:5):

[tex]1.24molNH_3*\frac{5molN_2}{4molNH_3}=1.55molN_2 \\\\1.79molNO*\frac{5molN_2}{6molNO}=1.50molN_2[/tex]

Thus, since NO yields the fewest moles of N2 product, we infer it is the limiting reactant.

NaHSO₄(s) --H₂O--> Na⁺(aq) + HSO₄⁻(aq)

Explanation:

Sodium hydrogen sulfate is a strong electrolyte, that is, when dissolved in water it completely dissociates into the cation sodium and the anion hydrogen sulfate. The corresponding chemical equation is:

NaHSO₄(s) --H₂O--> Na⁺(aq) + HSO₄⁻(aq)

Answer:

See explanation

Explanation:

If the spot in TLC is below the solvent front, it will be observed that the spot, instead of being separated by the solvent as expected, will just dissolve away in the solvent and zero actual separation of the mixture is achieved.

If the solute is dissolved away instead of being separated by the solvent, then the experiment fails because no actual separation of the mixture is achieved.

Hence, in TLC, the spot must be applied above the solvent front so that the capillary movement of the solvent through the plate can lead to the eventual separation of the components of the mixture since the various components of the mixture will travel at different speeds through the plate.

Also, if the solvent is above the spot, the solvent may evaporate selectively from the points above the spot while separation is ongoing.

Answer:

Cracking.

Explanation:

A chemical reaction can be defined as a reaction in which two or more atoms of a chemical element react to form a chemical compound. An example of a chemical reaction involving hydrocarbons is cracking.

Hydrocarbon can be defined as an organic compound that comprises of hydrogen and carbon only.

In Organic chemistry, cracking refers to the process of lowering the boiling point of a heavy, complex or long-chain hydrocarbon such as kerogens by exposing it to different environmental treatments such as hydrogen enriched catalysts, pressure or high temperatures, in order to produce smaller, lighter and more useful molecules (alkanes and alkenes) such as gasoline, diesel fuel, etc.

In this case, according to the given information, it turns out possible for us to calculate the concentration of the solution obtained, by knowing 20 mL of water are the same to 20 g and therefore the mass of the solution is 40g+20g=60g.

Next, we apply the following equation to obtain the required concentration:

Answer:

Starch.

Explanation:

When the triiodide combine with starch, it forms dark blue colour. Amylose in starch is responsible for the occurrence of a deep blue color when the iodine is combine with the starch. The iodine molecule goes inside of the amylose coil which makes a linear triiodide ion complex that goes into the coil of the starch that leads to an intense blue-black color in the end so we can say that starch turns the colour into blue.

Answer:

Which scientist developed the first model of the atom that showed the structure of the inside of an atom

Ernest Rutherford

Answer:

When Logan opens a new bottle of carbonated beverage, the sudden release of pressure causes the beverage to bubble up and overflow. What could Logan do in the future to prevent the next bottle from overflowing when he opens it.

Explanation:

This is an application of Boyle's law.

According to Boyle's law:

the volume of a fixed amount of gas is inversely proportional to its pressure at a constant temperature.

[tex]V \alpha \frac{1}{P}[/tex]

So, if pressure reduces all of a sudden, the volume increases and this causes an overflow of the beverage from the bottle.

To avoid this situation, the pressure inside the bottle should not be released at once. The bottle cap should be opened slowly in such a way that opens a little and then close again open a little and then close like that many times if we do, then pressure inside the bottle goes slowly then, the volume will not increase all of a sudden.

The element nitrogen exists as a gas  and is  obtained from air on a large scale​ by fractional distillation of air.

An element is defined as a substance which cannot be broken down further into any other substance. Each element is made up of its own type of atom. Due to this reason all elements are different from one another.

Elements can be classified as metals and non-metals. Metals are shiny and conduct electricity and are all solids at room temperature except mercury. Non-metals do not conduct electricity and are mostly gases at room temperature except carbon and sulfur.

The number of protons in the nucleus is the defining property of an element and is related to the atomic number.All atoms with same atomic number are atoms of same element.

D) a four-fold increase

Explanation:

According to Gay-Lussac's law, which states that the pressure of a given amount of gas is directly proportional to the temperature at a constant volume, the pressure increases with an increase in temperature.

According to this question, at a fixed volume, a four-fold increase in the temperature of a gas will lead to a four-fold increase in the pressure as well.
