The oxidation number of an element in a compound changes when the compound undergoes oxidation or reduction.

In oxidation, the oxidation number of the element increases, meaning it loses electrons. This happens because the compound loses electrons to another substance. In reduction, the oxidation number of the element decreases, meaning it gains electrons. This happens because the compound gains electrons from another substance. Therefore, the change in the oxidation number of an element in a compound indicates whether the compound is being oxidized or reduced.
When a compound is oxidized, the oxidation number of one of its elements increases, meaning it loses electrons during the reaction. On the other hand, when a compound is reduced, the oxidation number of one of its elements decreases, indicating that it gains electrons during the reaction. In summary, oxidation involves an increase in the oxidation number due to electron loss, while reduction involves a decrease in the oxidation number due to electron gain. These processes often occur simultaneously in redox reactions, where one species is oxidized and another is reduced.

Answer:

1) N-methyl-2-butanamine.

Explanation:

Secondary amines have 2 hydrogen atoms replaced by organic groups, so in this case, the secondary amine is N-methyl-2-butanamine:

The metal has a specific heat of 0.390 J/g°C.

What is Specific Heat ?

Specific heat is an important concept in thermodynamics and is used to determine the amount of heat required to raise the temperature of a material, or conversely, the amount of heat that is released when a material cools. Different materials have different specific heats, which means that they require different amounts of heat to change their temperature. For example, water has a very high specific heat, which means that it takes a lot of heat energy to raise its temperature, while metals have much lower specific heats and require much less heat energy to change their temperature.

We can use the formula for the heat absorbed or released by a material:

Q = m * c * ΔT

where Q is the heat absorbed or released, m is the mass of the material, c is the specific heat, and ΔT is the change in temperature.

In this case, the metal absorbs 57.2 J of heat, and the temperature of the sample rises 32°C. The mass of the metal is 4.70 g. When these values are added to the formula, we obtain:

57.2 J = 4.70 g * c * 32°C

Solving for c, we get:

c = 57.2 J / (4.70 g * 32°C)

= 0.390 J/g°C

Therefore, the specific heat of the metal is 0.390 J/g°C.

Answer:

detail is given below.

Explanation:

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

For example:

In given photosynthesis reaction:

6CO₂ + 6H₂O  → C₆H₁₂O₆ + 6O₂

The given equation is balanced chemical equation of photosynthesis. There are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

If equation is not balanced,

CO₂ + H₂O  → C₆H₁₂O₆ + O₂

It can not follow the law of conservation of mass because mass is not equal on both side of equation.

2 liters of the 80% acid solution must be added to 4 liters of the 20% acid solution to obtain a 40% acid solution.

Let's denote the number of liters of the 80% acid solution to be added as x.

To determine the amount of acid in the resulting solution, we can calculate the sum of the acids in the initial solutions and set it equal to the acid in the final solution.

The acid in the 80% solution (0.80x) added to the acid in the 20% solution (0.20 × 4 liters) should be equal to the acid in the final 40% solution (0.40 × (4 + x) liters).

This can be expressed as:

0.80x + 0.20 × 4 = 0.40 × (4 + x)

Simplifying the equation:

0.80x + 0.80 = 1.60 + 0.40x

Combining like terms:

0.80x - 0.40x = 1.60 - 0.80

Simplifying further:

0.40x = 0.80

Dividing both sides by 0.40:

x = 2

Therefore, 2 liters of the 80% acid solution must be added to 4 liters of the 20% acid solution to obtain a 40% acid solution.

Answer:

¹/₂₄ dm³ or 0.417 dm³

Explanation:

6.0 M = 6.0 mol/dm³

0.5 M = 0.5 mol/dm³

500 ml = 0.5 dm³

V = volume of 6.0 M solution required (dm³)

Volume × concentration = moles:

0.5 × 0.5 = 0.25

500 ml or 0.5 dm³ of 0.5 M solution contains 0.25 moles of HNO₃

We have 6.0 M solution available, we need 0.25 moles;

Using the formula, we can find the volume of the solution that contains this amount of moles:

6.0 × V = 0.25

V = 0.25/6

V = ¹/₄(¹/₆)

V  = ¹/₂₄

¹/₂₄ dm³ of the 6.0 M solution has the necessary moles of HNO₃ to achieve the desired volume of solution at the desired concentration;

Another liquid (or solution), such as water, without any HNO₃ must be used to make up the total 500 ml or 0.5 dm³, diluting the HNO₃ to the desired concentration:

0.5 - ¹/₂₄ = ¹²/₂₄ - ¹/₂₄

= ¹¹/₂₄

¹/₂₄ dm³ of the 6.0 M solution should be diluted with the ¹¹/₂₄ dm³ of liquid (0 M HNO₃ solution) to produce 0.5 dm³ of 0.5 M solution

When the anion gap exceeds 16 mEQ/L, the cause is generally an increase in fixed acids.

When the anion gap, which represents the difference between measured cations and anions in the blood, exceeds 16 mEQ/L, it is typically indicative of an increase in fixed acids. The anion gap is a valuable tool in diagnosing metabolic acidosis and evaluating the acid-base balance in the body.

An increase in fixed acids, such as lactic acid, ketoacids, or toxins, leads to an accumulation of these acidic substances in the blood. This causes a disturbance in the acid-base equilibrium, resulting in metabolic acidosis. Metabolic acidosis occurs when there is either a decrease in bicarbonate (base) or an increase in non-volatile acids (fixed acids) in the body.

An elevated anion gap indicates the presence of unmeasured anions, which are usually the result of increased fixed acids. These fixed acids can arise from various conditions, including diabetic ketoacidosis, lactic acidosis, renal failure, and certain toxic ingestions. By measuring the anion gap, healthcare professionals can identify the underlying cause of metabolic acidosis and guide appropriate treatment.

At 400 K, the free energy change (ΔG) for the reaction is 53.0 kcal. The total cost of producing 5,000 units is $50,250.

To find ΔG at 400 K using the Gibbs-Helmholtz equation, we need to substitute the given values of ΔH and ΔS into the equation.

ΔG = ΔH - TΔS

Given;

ΔH = 61.0 kcal

ΔS = 0.020 kcal/K

T = 400 K

Substituting these values into the equation;

ΔG = 61.0 kcal - (400 K)(0.020 kcal/K)

ΔG = 61.0 kcal - 8.0 kcal

ΔG = 53.0 kcal

Therefore, at 400 K, the free energy change (ΔG) for the reaction is 53.0 kcal.

To find the total cost of producing 5,000 units using the cost equation y = 10x + 250, we need to substitute x = 5,000 into the equation.

y = 10x + 250

Given;

x = 5,000

Substituting x = 5,000 into the equation:

y = 10(5,000) + 250

y = 50,000 + 250

y = 50,250

Therefore, the total cost of producing 5,000 units is $50,250.

The total energy of a system consisting of a jar full of water can be increased by adding heat or doing work on the system. Heat can be added to the system by placing the jar of water on a hot plate or by adding hot water to the jar. This will increase the thermal energy of the water molecules.

It will increase the total energy of the system. Doing work on the system can involve stirring the water with a spoon or shaking the jar. This will increase the kinetic energy of the water molecules, which will also increase the total energy of the system. It is important to note that the total energy of a closed system such as the jar of water is conserved, which means that the increase in one form of energy such as thermal or kinetic will result in a corresponding decrease in another form of energy such as potential or chemical.

You can increase the total energy of the jar of water by heating it up, which increases the waters internal thermal energy. This can be achieved by placing the jar on a heat source, like a stove or a hot plate. As the temperature of the water increases, the internal energy increases as well. Another way to increase the total energy of the system is by raising the jar of water to a higher altitude. By doing so, you are increasing its potential energy, which is the energy an object has due to its position relative to other objects. For example, you could place the jar on a shelf or a higher surface, and as a result, its potential energy increases.

Explanation:

The final temperature of the mixture of 20c and 40c water would be 30c.

Temperature is a physical property of matter that quantitatively expresses the common notions of hot and cold.
This is due to the law of conservation of energy, which states that the total energy of a closed system remains constant. The total energy of the two waters together is the same, so the final temperature must be the average of the two. The total mass of the two waters is 100g, and the temperature difference between them is 20c.

So, the final temperature of the mixture is 20c + (20c/100g) x 50g = 30c.
This principle is also known as the "law of mixing temperatures" and is used in many scientific and engineering applications. For example, it is used to calculate the temperature of a mixture of two fluids, or to calculate the cooling of a hot object in a room.
This law can be further extended to mixtures of more than two fluids, as long as the total energy of the system is conserved. This means that the total mass, the specific heat capacity of each fluid, and the temperature of each fluid must all be known in order to calculate the final temperature. This can be a useful tool in engineering applications, such as the cooling of a computer chip or the heating of a room.
In summary, the final temperature of a mixture of two fluids, such as the 50g of 20c and 50g of 40c water, is the average of the two temperatures. The final temperature of the mixture is 30c.
