Answer:

Plastic is a insulator that is why it is used

Explanation:

So wires or metal is a conductor and if you put a conductor as coating then it will conduct plastic coating is for protection because it does not conduct electricity or let it pass through that is why you don't get shocked but if coating was metal then it would conduct and you would get shocked.

Answer:

plastics don't conduct any electricity whatsoever, so plastic is actually used in a wide variety of applications where their insulating, or "protecting" properties are needed. PVC is the most common insulator for electric wiring, I know, because my dad's friend works in electrical and that's what he mainly uses in his line of work, but anyway. yeah, so, plastic materials such as PVC also helps with the prevention of electrical shock. obviously if you were to touch a bare electrical wire you would either be in for a long hospital stay or a coffin. lol um so yeah materials such as PVC are very good and are always used in electrical wiring to not only prevent electrical shock, but to also to provide an insulator and is good for use in high temperatures.

The aldehyde group reacts with hydrazoic acid to form the oxadiazoline intermediate. This reaction is typically initiated by the acid catalyst H+.

The Schmidt rearrangement is a chemical reaction that involves the conversion of a ketone or aldehyde functional group into an amine or imine functional group using hydrazoic acid in the presence of an acid catalyst, typically H+. During this reaction, the hydrazoic acid adds to the carbonyl group of the aldehyde to form an intermediate called an oxadiazoline. The oxadiazoline is then converted to an isocyanate, which undergoes rearrangement to form an amine or imine functional group.
The hydrazoic acid adds to the carbonyl group of the aldehyde, resulting in the formation of a tetrahedral intermediate. This intermediate then rearranges to form the oxadiazoline intermediate.
It is important to note that the Schmidt rearrangement is a highly reactive and potentially dangerous reaction. Hydrazoic acid is a highly toxic and volatile substance that requires careful handling. Additionally, the reaction can produce potentially explosive byproducts, so proper precautions must be taken when conducting this reaction.

After adding sodium hydroxide, sodium ions a solid precipitate is first observed.

In an aqueous solution, precipitation is the most common way of changing a broke down substance into an insoluble strong from a super-immersed solution. The strong framed is known as the precipitate. In the event of an inorganic compound response prompting precipitation, the synthetic reagent making the strong structure is known as the precipitant.

The unmistakable fluid excess over the accelerated or the centrifuged strong stage is additionally called the 'supernate' or 'supernatant'.

The notion of precipitation can likewise be reached out to different spaces of science (natural science and organic chemistry) and, surprisingly, be applied to the strong stages (e.g., metallurgy and composites) when strong debasements isolate from a strong stage.

Answer:

2.00 Cups

Explanation:

This question isn't really possible without the density of the sugar, you can pack it tighter like if you have sugar cubes for example, but a quick search gives a density of 1.59 g/mL, so that what I will use.

Let's get the number of grams of sucrose (molar mass 342.3 g/mol) we have by taking 342.3 g/mol * 0.880 mol. Moles cancel and we get 301.224 grams of sucrose.

Now we just need to take the density, there is one mL for every 1.59 grams of sucrose, so we will take (301.224 g)/(1.59 g/mL). grams cancel and we are left with 478.94616 mL.

The question asked for cups (I'm assuming US cups) though, so let's convert by dividing by 240 to give us 1.995609 cups. Or when we round to sig figs we get 2.00 cups.

Answer:

To put some order into his study of chemical elements, Mendeleev made up a set of cards, one for each of the 63 elements known at the time.

Explanation:

3 g/mL is the density in grams per millititer to three significant figures.

To express the density of a cube of butter in grams per milliliter, we need to convert the weight from pounds to grams and the volume from cubic inches to milliliters.

1 pound is approximately equal to 453.592 grams, so the weight of the cube of butter in grams would be:
0.260 lb * 453.592 g/lb = 117.81992 g (rounded to three significant figures as 118 g)

1 cubic inch is equal to approximately 16.387 milliliters, so the volume of the cube of butter in milliliters would be:
\(1303 cubic inches * 16.387 mL/in^3 = 21,365.861 mL\) (rounded to three significant figures as 21,400 mL)

Therefore, the density of the cube of butter would be:
Density = Mass / Volume

= 118 g / 21,400 mL

= 0.00551 g/mL (rounded to three significant figures as 0.005 g/mL)

For the gem, we already have the mass as 600 g and the volume as 200 mL.

Therefore, the density of the gem would be:
Density = Mass / Volume

= 600 g / 200 mL

= 3 g/mL (rounded to three significant figures)

The combination of temperature and pressure that gives the highest equilibrium yield of methanol is option B, with a temperature of 200°C and a pressure of 200 atmospheres. Option B

To determine the combination of temperature and pressure that gives the highest equilibrium yield of methanol, we need to consider the Le Chatelier's principle, which states that a system at equilibrium will shift in a way to counteract any changes imposed upon it.

In this case, since the forward reaction is exothermic, increasing the temperature will shift the equilibrium in the reverse direction to absorb the excess heat. Therefore, a lower temperature is favored to maximize the equilibrium yield of methanol.

Looking at the given options, options A and B have a temperature of 200°C, while options C and D have a temperature of 600°C. Based on the principle mentioned above, options A and B with the lower temperature of 200°C are more favorable for a higher equilibrium yield of methanol.

Now let's consider the pressure. According to the balanced equation, the stoichiometric ratio of CO to H2 in the forward reaction is 1:2. Therefore, increasing the pressure will favor the formation of methanol.

Comparing the pressure options, options A and C have a pressure of 10 atmospheres, while options B and D have a pressure of 200 atmospheres. Based on the principle mentioned above, options B and D with the higher pressure of 200 atmospheres are more favorable for a higher equilibrium yield of methanol. Option B

Isoborneol is the major product in the reduction of camphor with borohydride because borohydride is an effective reducing agent, and isoborneol is the most thermodynamically stable product of the reaction.

The borohydride anion acts as a nucleophile and attacks the carbonyl carbon of camphor from the least hindered side. This leads to the formation of isoborneol as the major product, as it is the most stable and energetically favored product.

In addition, the reduction of camphor with borohydride is a stereoselective reaction, meaning that it preferentially produces one stereoisomer over another. In this case, isoborneol is the preferred product due to its more stable conformation.

The pH of a soapy solution decreases as a result of the introduction of hardness ions.

Soapy solutions are typically basic, with a pH above 7. However, when hardness ions, such as calcium or magnesium, are introduced to the solution, they can react with the soap molecules to form insoluble salts, which reduces the effectiveness of the soap. As a result, more soap may be needed to achieve the desired cleaning effect. Additionally, the removal of weak bases such as RCO2– (which are present in soap molecules) can result in a decrease in pH, as this leads to a decrease in the concentration of hydroxide ions ([OH-]). This decrease in pH can lead to a more acidic environment, with a greater concentration of hydrogen ions ([H+]) compared to hydroxide ions, which can affect the effectiveness of the soap and may require adjustments to the cleaning process.

a) The hydroxide ion concentration is 10 M

b) The number of moles of the hydrogen ions is 1 * 10^- 13 moles

c) The pH of the solution is 4.

We know that the pH of the solution has to do with the amount of the hydrogen ions that we have in a solution. Looking at the fact that the number of the hydrogen or the hydroxide ions that is in the solution is the basis that we can use to decide whether the solution can be said to be acidic or not.

a) If the pH has been given for the solution as 13 then

Hydrogen ion concentration = Antilog (-13) = 1 * 10^-13 M

It then follows that; \([OH^-] [H^+] = 1 * 10^-14\)

Then \(OH^-\) = 1 * 10^-14/1 * 10^-13 M

= 10 M

The number of moles per liter of the hydrogen ions would be;

Concentration * volume

= 1 * 10^-13 M * 1 L

= 1 * 10^-13 moles
