The given chemical equation, 2N₂ + 3H₂ <==>2NH3, is an example of a reversible reaction.option A.

The double arrows between the reactants and products indicate that the reaction can proceed in both directions, forming both products and reactants.The reversible reaction, also known as a chemical equilibrium reaction, refers to a chemical reaction that can occur in both forward and reverse directions. It occurs when reactants are converted into products, and the products are also converted back into the original reactants.A reversible reaction can be identified by the symbol “<==>” or “⇌” that appears between the reactants and products in the chemical equation. It denotes that the reaction is in a state of chemical equilibrium. When the reactants and products have achieved equilibrium, the rate of the forward and reverse reactions is equal, and there is no further net change in the amounts of the reactants and products.A combustion reaction is a type of exothermic reaction in which a substance reacts with an oxidizing agent to produce heat and light. A one-way reaction is a type of reaction that occurs in only one direction and cannot be reversed without significant changes to the reaction conditions, such as changing the temperature or pressure.A reversible reaction, unlike a one-way reaction, can occur in both directions and reach equilibrium when the forward and reverse reaction rates are equal.option A.

The property X is an extrinsic property.

The term extensive property refers to the type of property that depends on the amount of the substance present. We must recall that an intensive property does not in any way depend on the number or the amount of the substance present in the sample.

If we have a good look at the table that is being referred to here, we would see that the mass of the substance tends to increase as a certain un named property of the substance X is increasing. This implies that the property X is affected by the mass of the object which is the quantity of matter in the object. This gives us an idea that the property that we are referring to can not be an intrinsic  property since it varies with the mass of the substance that is under study as shown.

At 25 °C a solution having a pOH of 2.33. The [H₃O⁺] of the solution is 2.08 × 10⁻¹² M, and the solution is basic.

To find the [H₃O⁺] of the solution, we first need to use the relationship between pH and pOH;

pH + pOH = 14

Rearranging the equation, we get;

pH = 14 - pOH

Substituting the given value of pOH into equation, we have;

pH = 14 - 2.33 = 11.67

Next, we use the relationship between pH and [H₃O⁺];

pH = -log[H₃O⁺]

Substituting the value of pH we just calculated, we have;

11.67 = -log[H₃O⁺]

Taking the antilog of both sides, we get;

[H₃O⁺] = 2.08 × 10⁻¹² M

Therefore, the [H₃O⁺] is less than 1 × 10⁻⁷ M, the solution is basic.

Answer:

At RTP (room temperature and pressure), one mole of any ideal gas occupies a volume of 24.45 dm³. Therefore, we can use the following steps to calculate the number of molecules of nitrogen dioxide in 3 dm³ at RTP:

Calculate the number of moles of nitrogen dioxide in 3 dm³ using the ideal gas law:

PV = nRT

Where:

P = pressure = 1 atm (at standard pressure)

V = volume = 3 dm³

n = number of moles (unknown)

R = gas constant = 0.0821 L atm/(mol K)

T = temperature = 298 K (at standard temperature)

n = PV/RT

n = (1 atm)(3 dm³)/(0.0821 L atm/(mol K) x 298 K)

n = 0.122 mol

Calculate the number of molecules of nitrogen dioxide in 0.122 mol using Avogadro's number:

1 mol of any substance contains 6.022 x 10^23 molecules (Avogadro's number)

Therefore, the number of molecules in 0.122 mol of nitrogen dioxide is:

6.022 x 10^23 molecules/mol x 0.122 mol = 7.35 x 10^22 molecules

Therefore, there are 7.35 x 10^22 molecules of nitrogen dioxide in 3 dm³ at RTP.

Now, to find the grams of NH that will be produced, we will follow these steps:

1. We find the moles of N2 and H2 by dividing the grams by the molar mass of each element.

Molar Mass N2=28.0g/mol

Molar Mass H2=2.0g/mol

2. By stoichiometry we find out which is the limiting reactant, we see that for each mole of H2 one mole of N2 reacts, therefore, the limiting reactant will be the one with the least number of moles. The other reactant will be the excess reactant

3. We find the moles of NH using the limiting reactant.

4. We find the grams of NH by multiplying the moles by the molar mass of NH.

5. We find how much of the excess reactant is left by subtracting the initial moles minus the reacting moles.

Let's proceed with the calculations

1. Moles of N2 and H2

2. Limiting reactant

We see that there are 22.5 moles of H2 and 1.25 moles of N2. The ratio N2 to H2 is 1/1, therefore, the limiting reactant will be the one with fewer moles, since it will be consumed faster. Therefore, the limiting reactant is nitrogen.

Taking into account the definition of dilution, the final concentration of the solution is 0.68 M.

Dilution is the process of reducing the concentration of solute in solution, which is accomplished by simply adding more solvent to the solution.

In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, and the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

Explanation:that is right

The amount, in liters, of the 0.2M NaCl solution required to measure out 3.0 grams of NaCl is 0.25 Liter.

Recall that the molarity of a solution is the ratio of the number of moles of solutes in the solution to the volume of the solution.

Molarity = number of moles/volume in Liters

Thus, a 0.2M NaCl solution contains 0.2 moles of NaCl in 1 Liter of the solution.

But 3.0 grams of NaCl is needed. Recall that:

Number of moles = mass/ molar mass

3.0 grams of NaCl = 3.0 grams/58.88 g/mole = 0.051 moles

If 1 Liter of the solution contains 0.2 moles of NaCl, then the amount of the solution that will contain 0.051 moles (3.0 grams) will be:

               1 x 0.051/0.2 = 0.25 Liter
