No, the volume of water in a beaker is not an extensive property.

Extensive properties are those that depend on the amount or size of the substance being measured. In other words, they are properties that change with the quantity of the substance. Examples of extensive properties include mass, volume, and total energy.

In the given scenario, the volume of water in the beaker is 50 milliliters. This volume remains the same regardless of the quantity of water present. Whether it's 50 milliliters or 500 milliliters, the volume measurement does not change. Therefore, the volume of water in the beaker is an example of an intensive property.

Intensive properties are independent of the amount or size of the substance. They are characteristics that remain constant regardless of the quantity of the substance. Examples of intensive properties include temperature, density, and color.

It's important to note that the distinction between extensive and intensive properties depends on the specific property being considered. While volume is typically an extensive property for a bulk substance, in the case of a fixed volume of water in a beaker, it becomes an intensive property.

In summary, the volume of water in a beaker is not an extensive property but rather an intensive property because it does not change with the quantity of the substance.

The endothermic reaction taking place at constant pressure: q = + , ΔH = +, w = +

Endothermic reactions are reactions that absorb heat (heat is removed from the surroundings to the system) Endothermic reactions (endo- is the prefix meaning "into"), in which heat must be transferred to the system by the surroundings.

According to the condition given in the question we have given the reaction.

                             3O₂ (g) → 2O₃ (g)

The reaction is endothermic which means heat is absorbed.

For any endothermic reaction, the sign is POSITIVE.

Now, if we see moles, the number of moles from the reactant side to the product side is decreasing.

If the number of moles is decreasing, then the volume should decrease.

If the volume is decreasing, it indicates that the work is done on the system.

If the work is done on the system then the sign should be always POSITIVE

Now as the heat is absorbed so the sign of q should be POSITIVE

Therefore, the correct option is q = +, ΔH = +, w = +

Your question is incomplete but most probably your full question was:

Sodium chloride is an ionic compound because it is composed of ions, specifically sodium cations (Na+) and chloride anions (Cl-), which are held together by electrostatic forces.

When sodium chloride is dissolved in water, the polar water molecules surround the ions and separate them from each other.

This process is called hydration or solvation. The water molecules form a hydration shell around each ion, with the positively charged sodium ions surrounded by the negatively charged ends of water molecules (oxygen atoms), and the negatively charged chloride ions surrounded by the positively charged ends of water molecules (hydrogen atoms). This dissociation of the ionic compound in water leads to the formation of a solution that conducts electricity due to the presence of the separated ions. Overall, the dissolution of sodium chloride in water is an example of an ionic compound undergoing dissociation and solvation.

Sodium chloride (NaCl) is an ionic compound. When NaCl is dissolved in water, the sodium (Na+) and chloride (Cl-) ions separate from each other due to the polar nature of water molecules. The positively charged Na+ ions are attracted to the negative oxygen ends of the water molecules, while the negatively charged Cl- ions are attracted to the positive hydrogen ends of the water molecules. This results in the formation of a hydration shell around each ion, leading to the dissolution of NaCl in water.

Taking into account the definition of calorimetry, the correct answer is las option: the initial temperature of the copper piece is 364°C.

Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is defined as the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c×m×ΔT

where:

In this case, you know:

Replacing in the expression to calculate heat exchanges:

If two isolated bodies or systems exchange energy in the form of heat, the quantity received by one of them is equal to the quantity transferred by the other body. That is, the total energy exchanged remains constant, it is conserved.

Then, the heat that the copper gives up will be equal to the heat that the water receives. Therefore:

- Qcopper = + Qwater

- 0.39 J/gC × 240 g× (42 C - Initial temperature of copper)= 4.18 J/gC× 400 g× (42 C - 24 C)

Solving:

- 93.6 J/C× (42 C - Initial temperature of copper)= 30,096 J

- 93.6 J/C× 42 C- (- 93.6 J/C)× Initial temperature of copper= 30,096 J

- 3,931.2 J +93.6 J/C × Initial temperature of copper= 30,096 J

93.6 J/C × Initial temperature of copper= 30,096 J+ 3,931.2 J

93.6 J/C × Initial temperature of copper= 34,027.2  J

Initial temperature of copper=34,027.2  J÷ 93.6 J/C

Initial temperature of copper= 364 °C

Finally, the initial temperature of the copper is 364 °C.

Answer:

the correct answer is 364

q = m * c * ΔT

where q is the heat absorbed or released, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

We can assume that the heat lost by the copper is gained by the water, so:

q(copper) = -q(water)

where the negative sign indicates that the copper loses heat while the water gains heat.

The specific heat capacity of copper is 0.39 J/g °C, so:

q(copper) = 240.0 g * 0.39 J/g °C * (T(copper) - 24.0 °C)

The specific heat capacity of water is 4.18 J/g °C, so:

q(water) = 400.0 g * 4.18 J/g °C * (42.0 °C - T(copper))

Setting q(copper) equal to -q(water), we get:

240.0 g * 0.39 J/g °C * (T(copper) - 24.0 °C) = -400.0 g * 4.18 J/g °C * (T(copper) - 42.0 °C)

Simplifying and solving for T(copper), we get:

T(copper) = [(400.0 g * 4.18 J/g °C * 42.0 °C) + (240.0 g * 0.39 J/g °C * 24.0 °C)] / (240.0 g * 0.39 J/g °C + 400.0 g * 4.18 J/g °C)

T(copper) = 364.1 °C

Therefore, the initial temperature of the copper piece was 364.1 °C.

Hence, the answer is "364 °C".

Explanation:

Answer:

B, C, and D are fluids.

Explanation:

The volume of the gas changed by approximately 0.280 m³ during the process.

To find the change in volume of the gas during the process, we can use the equation:

ΔQ = nCvΔT

where: ΔQ is the heat absorbed (3870 J),

n is the number of moles of the gas (7.70 mol),

Cv is the molar heat capacity at constant volume,

ΔT is the change in temperature (24.2 °C = 24.2 K).

Since the change in internal energy is zero (ΔU = 0), we know that ΔU = ΔQ + ΔW, where ΔW is the work done by the gas. In this case, since the process is at constant pressure, we can write ΔW = PΔV, where P is the pressure (1.62E+5 Pa) and ΔV is the change in volume.

Now, using the ideal gas law, we can express ΔV in terms of ΔT:

ΔV = (nRΔT) / P

where R is the ideal gas constant (8.314 J/(mol·K)).

Substituting the given values into the equations:

ΔQ = nCvΔT

3870 J = 7.70 mol × Cv × 24.2 K

From the equation ΔV = (nRΔT) / P, we have:

ΔV = (7.70 mol × 8.314 J/(mol·K) × 24.2 K) / (1.62E+5 Pa)

Simplifying the equations and performing the calculations:

ΔQ = nCvΔT

3870 J = 7.70 mol × Cv × 24.2 K

Cv ≈ 2.00 J/(mol·K) (calculated from the above equation)

ΔV = (7.70 mol × 8.314 J/(mol·K) × 24.2 K) / (1.62E+5 Pa)

ΔV ≈ 0.280 m³

Therefore, the volume of the gas changed by approximately 0.280 m³ during this process.

The reason we learn an algebraic method to balance chemical equations instead of using a trial-and-error method is because the algebraic method is more efficient and reliable.

Using trial and error can be time-consuming and may not always lead to the correct solution. Balancing chemical equations requires ensuring that the number of atoms of each element on both sides of the equation is equal. This can become complex when dealing with more complicated equations.

The algebraic method, on the other hand, provides a systematic approach that can be applied to any chemical equation, regardless of its complexity. By applying mathematical principles and using variables, we can determine the correct coefficients to balance the equation. This method is programmable, which means we can use computer algorithms to solve equations more quickly and accurately.

Additionally, the algebraic method allows us to analyze whether a reaction can actually be balanced. It helps us understand the stoichiometry of the reaction and determine the correct ratios of reactants and products.

Contrary to the belief that it is only meant to complicate things, learning this method is essential for a deeper understanding of chemistry and problem-solving skills. It enables us to apply logical thinking and mathematical concepts to chemical reactions, which is crucial in various scientific and industrial applications.
