Aqueous potassium carbonate was mixed with aqueous copper (1) fluoride and a crystallized copper (1) carbonate product was formed. A crystalized product is a solid. The other product, potassium fluoride, remains dissolved in solution. Consider the other product and it’s phase, and then write the balanced molecular equation for this precipitation reaction. Express your answer as a chemical equation including phases. Type an underscore (_) or a carat (^) to add subscripts and superscripted more quickly.

Answers

Answer 1

Answer: The balanced molecular equation for the precipitation reaction is [tex]K_2CO_3(aq)+2CuF(aq)\rightarrow Cu_2CO_3(s)+2KF(aq)[/tex]

Explanation:

A precipitation reaction is defined as the reaction where a solid precipitate (solid substance) is formed at the end of the reaction. It is insoluble in water.

When potassium carbonate reacts with copper (I) fluoride, it leads to the formation of solid copper (I) carbonate and potassium fluoride solution.

The balanced chemical equation follows:

[tex]K_2CO_3(aq)+2CuF(aq)\rightarrow Cu_2CO_3(s)+2KF(aq)[/tex]

The precipitate formed is copper (I) carbonate

(a) Describe the process by which Nitrogen is obtained from air on a large scale​

Answers

Nitrogen is produced commercially almost exclusively from air, most commonly by the fractional distillation of liquid air. In this process, air is first cooled to a temperature below that of the boiling points of its major components, a temperature somewhat less than - 328°F (-200°C).

What is an element?

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.

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)

At a fixed volume, a four-fold increase in the temperature of a gas will lead to _______ in pressure.
Question 2 options:

A)

no change

B)

a two-fold decrease

C)

a four-fold decrease

D)

a four-fold increase

Answers

Answer:

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.

What term describes the process of lowering the boiling point of a hydrocarbon by exposing it to different environmental treatments such as hydrogen enriched catalysts or high temperatures

Answers

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.

What volume would 0.853 moles of Nitrogen gas occupy at STP?

Answers

Answer:

19.12 L

Explanation:

At STP(i.e. Standard temperature and pressure).

The volume occupied by one mole of gas = 22.4 L

The pressure = 1 atm

The temperature = 273 K

Thus, since 1 mole of gas = 22.4 L;

Then 0.853 moles of N2 gas will occupy:

= (0.853 moles of N2 gas × 22.4 L)/ 1 mole of N2 gas

= 19.12 L

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:

4-chloroaniline, benzoic acid and 1,4-dibromobenzene. Prepare a flow chart to illustrate the process of separation for each component.

Answers

Answer:

The flow chart is found in the attachment

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

Answers

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.

Why must the spot applied to a TLC plate be above the level of the developing solvent? What problem will ensue if the level of the developing liquid is higher than the applied spot in a TLC analysis?

Answers

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.
