When reglazing, you cover the areas that were forgotten in the 2nd firing as well as reglaze everywhere for a uniform appearance.

Reglazing involves applying a new layer of glaze to a previously fired ceramic piece to improve its appearance, fix any issues from previous firings, or to achieve a specific effect.

In your case, if some areas were missed or improperly glazed during the 2nd firing, you would want to apply glaze to those forgotten areas to ensure a consistent finish.

However, it's important to reglaze the entire piece, not just the missed areas, to maintain a uniform appearance and avoid any inconsistencies in the final result. Before reglazing, make sure the ceramic piece is clean and free of dust or debris.

Apply the glaze evenly, using an appropriate technique such as brushing or dipping, and then fire the piece again according to the glaze's specific firing temperature and instructions. This should result in a well-glazed and visually appealing ceramic piece.

The reaction's yield as a percentage is 89.8%.

The balanced chemical equation for the reaction is:

\(SiO_2\) + 3C -> \(SiC\) + \(_2CO\)

The molar mass of SiO2 is 60.08 g/mol and the molar mass of \(SiC\) is 40.10 g/mol.

We can calculate the theoretical yield of \(SiC\) based on the amount of \(SiO_2\) used:

mol \(SiO_2\) = 48.7 g / 60.08 g/mol = 0.811 mol \(SiO_2\)

mol \(SiC\) = 0.811 mol \(SiO_2\) × 1 mol \(SiC\) / 1 mol \(SiO_2\) = 0.811 mol \(SiC\)

mass \(SiC\) = 0.811 mol \(SiC\) × 40.10 g/mol = 32.5 g \(SiC\)

Therefore, the theoretical yield of \(SiC\) is 32.5 g.

The actual yield of \(SiC\) is given as 29.2 g.

The percent yield of the reaction is:

percent yield = (actual yield / theoretical yield) × 100%

percent yield = (29.2 g / 32.5 g) × 100% = 89.8%

Therefore, the percent yield of the reaction is 89.8%.

The average mass in grams of one uranium atom is 3.953×10^−22 g (Option C).

The atomic mass of uranium is 238.03 g/mol. This means that one mole of uranium atoms has a mass of 238.03 g and contains 6.022 × 10^23 atoms.

To find the average mass in grams of one uranium atom, we need to divide the molar mass of uranium by Avogadro's number.

Average mass of one atom = (Molar mass) / (Avogadro's number)

It is given that, Molar mass of Uranium = 238.03 g/mol

Avogadro's number = 6.022×10^23 atoms / mol

Average mass of one atom of Uranium =  Molar mass of Uranium/ Avogadro's number

CuSO4 is soluble in water but ferric oxide is not soluble in water.

Ferric oxide is an insoluble oxide hence it does not dissolve in water. Since the substance is insoluble in water, it exists as solid particles when added to water. When this mixture is filtered,  ferric oxide is separated from water.

On the other hand, copper (II) sulfate is quite soluble in water hence it can not be separated from water by filtration since it dissolves completely in water. Hence, copper (II) sulfate can not be separated from water by filtration but ferric oxide can be separated from water by filtration.

A solid material with a Fermi level within the band gap between conduction and valence bands is a semiconductor.

A semiconductor is a material that falls somewhere between an insulator like glass and a conductor like copper in terms of electrical conductivity. Its resistivity decreases as its temperature increases; Semiconductors are materials with a conductivity between conductors (usually metals) and non-conductors or insulators (like ceramics).

Metals behave in the opposite way. Compounds like gallium arsenide and pure elements like silicon and germanium are examples of semiconductors. A semiconductor is a material with a higher electrical resistance than insulators but a lower electrical resistance than conductors. As a result, it is able to conduct current more slowly than insulators but does not impede the flow of current like insulators do.

True. They may both be properties of a gas but they are independent of each other since the pressure of a gas may vary without changing the temperature or volume (or any other properties).

Answer:

True

Explanation:

The statement "The qualities/quantities of a gas are independent of one another" is True. This means that a change in one property of a gas, such as pressure, volume, or temperature, does not affect the other properties. This is one of the basic assumptions of the ideal gas law, which states that the pressure, volume, and temperature of a gas are proportional to one another under certain conditions.

For example, when the volume of a gas is increased, its pressure decreases, and when its temperature is increased, its pressure also increases. These changes in properties are independent of one another, and can be described by the mathematical relationships described by the ideal gas law.

Answer:

2.5 g of platinum

Explanation:

Recall that a catalyst is a specie added to a reaction system to increase the rate of reaction. A catalyst does not participate in the chemical reaction hence it remains unchanged at the end of the chemical reaction. A catalyst merely provides an alternative reaction pathway by lowering the activation energy of the reaction system. Hence a catalysed reaction usually proceeds faster with less energy requirement than the uncatalysed reaction.

Since the catalyst does not participate in the reactions and remains unchanged at the end of the reaction, the mass of platinum will remain the same (2.5g). The mass can only change if a specie participates in the chemical reaction. Hence the answer.

To make a 48% solution from 25 g of solute, you would need approximately 52.08 mL of solvent.

To calculate the volume of solvent required, we need to consider the mass percent of the solution. The mass percent is defined as the ratio of the mass of solute to the total mass of the solution, multiplied by 100. In this case, the mass percent is given as 48%.

To find the volume of solvent, we can set up a proportion using the mass percent. Let's assume the total volume of the solution is V mL. We can set up the following equation:

(25 g)/(V mL) = (48 g)/(100 mL)

Cross-multiplying and solving for V, we get:

25V = 48 * 100

V = (48 * 100)/25

V ≈ 192 mL

Therefore, you would need approximately 192 mL of the solvent to make a 48% solution from 25 g of solute.

The component that was not included in the Urey-Miller experiment is oxygen. Option b is the answer.

Urey-Miller experiment was conducted to investigate the origin of life on earth. The experiment was done in the 1950s by two researchers, Harold Urey and Stanley Miller. The experiment aimed to investigate the evolution of early life forms from organic compounds. The experiment began by simulating the earth's primitive atmosphere. This simulation was done by adding water vapor to a flask containing gases like ammonia, methane, and hydrogen.

Then, sparks were introduced to the mixture to simulate the lightning that was present on early Earth. The results of this experiment showed that the organic compounds were able to form amino acids and other complex organic molecules that are necessary for life. These findings suggested that the building blocks of life could have been formed under the conditions that existed on early Earth. In conclusion, oxygen was not part of the Urey-Miller experiment.
