Answer:

HCl+ NaoH- Nacl+H2O

Explanation:

base react with acid

The time taken for the decomposition to occur is  109 hours.

When we are told that the reaction is a decomposition this implies tat the process would follow the first order kinetics as we can see in the question.

Initial pressure of the pure gas = 600. mmHg or 0.79 atm

Final pressure of the system =  1.000 atm

Final pressure of the pure gas =  1.000 atm - 0.79 atm = 0.21 atm

We now have;

0.693/\(t_{\frac{1}{2} }\) = 2.303/t log Po/P

\(t_{\frac{1}{2} }\)  half life of the system

t = time taken

Po = initial pressure of the pure gas

P = final pressure of the pure gas

Then;

0.693/ 8.75 = 2.303/t log 0.79/0.21

0.0792 = 8.66/t

t =  8.66/0.0792

t = 109 hours

Explanation:

The substances can be identified as follows: \(HNO_3\) is an acid, KOH is a base, \(H_3SO_4\) is an acid, NaCl is neither an acid nor a base, and \(Ca(OH)_2\) is a base.

1. \($\text{HNO}_3$\) is nitric acid, which is a strong acid. It dissociates in water to release \($\text{H}^+$\) ions, making the solution acidic. Thus, \($\text{HNO}_3$\) is an acid.

2. \($\text{KOH}$\) is potassium hydroxide, which is a strong base. When dissolved in water, it dissociates to release \($\text{OH}^-$\) ions, leading to an alkaline solution. Therefore, \($\text{KOH}$\) is a base.

3. \($\text{H}_3\text{SO}_4$\) is sulfuric acid, a strong acid commonly used in laboratories and industrial processes. It dissociates in water to form \($\text{H}^+$\) ions, making the solution acidic. Hence, \($\text{H}_3\text{SO}_4$\) is an acid.

4. \($\text{NaCl}$\) is sodium chloride, which is a salt. It is formed by the reaction of a strong acid (e.g., \($\text{HCl}$\)) and a strong base (e.g., \($\text{NaOH}$\)). In aqueous solutions, it dissociates into \($\text{Na}^+$\) and \($\text{Cl}^-$\) ions, but it does not significantly alter the pH of the solution. Therefore, \($\text{NaCl}$\) is neither an acid nor a base.

5. \($\text{Ca(OH)}_2$\) is calcium hydroxide, a strong base often referred to as slaked lime. It dissociates in water, releasing \($\text{OH}^-$\) ions and creating an alkaline solution. Hence, \($\text{Ca(OH)}_2$\) is a base.

Answer:

P₂ = 113.49 kPa

Explanation:

Given that,

Initial pressure, P₁ = 101 kPa

Initial temperature, T₁ = 10.0°C = 283 K

Final temperature, T₂ = 45°C = 318 K

The relation between pressure and temperature is given by :

\(\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}\)

Where

P₂ is the new pressure

So,

\(P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{101 \times 318}{283 }\\\\P_2=113.49\ kPa\)

So, the new pressure is equal to 113.49 kPa.

Washing up liquid is used in enzyme experiments as a tool to help control the reaction conditions and to demonstrate the power and versatility of enzymes.

Washing up liquid is used in enzyme experiments for several reasons:

To break down grease and oils: Enzymes are commonly used in laundry detergents and dishwashing liquids to help break down grease and oils on clothing and dishes. In enzyme experiments, washing up liquid can be used to simulate this effect and demonstrate the power of enzymes.

To increase the surface area for reaction: By adding washing up liquid to an enzyme experiment, the surface area for reaction is increased, allowing the enzymes to react with a larger amount of substrate and produce more product.

To act as a surfactant: Washing up liquid contains surfactants, which are compounds that lower the surface tension of liquids and allow the enzymes to diffuse into the substrate more easily. This helps to increase the reaction rate of the enzymes.

To control the viscosity of the reaction mixture: Washing up liquid can also help to control the viscosity of the reaction mixture, allowing the enzymes to move freely and react with the substrate.

The standard enthalpy of the solution of KCl is +113.9 kJ/mol.

The standard enthalpy of solution (ΔHsoln) for a solute is defined as the enthalpy change when one mole of the solute dissolves completely in a specific solvent. In this case, we are interested in the standard enthalpy of the solution of KCl.

We can use Hess's Law, which states that the total enthalpy change of a chemical reaction is independent of the pathway between the initial and final states. Using this law, we can calculate the standard enthalpy of the solution of KCl from the given enthalpies of formation.

The enthalpy change for the dissolution of KCl(s) in water can be represented by the following equation:

\($KCl(s) \rightarrow K^+(aq) + Cl^-(aq)$\)

The enthalpy change for this reaction can be calculated using the enthalpies of formation of KCl(s), K+(aq), and Cl-(aq) as follows:

\($\Delta H_1 = \sum n \Delta H_f(\text{products}) - \sum n \Delta H_f(\text{reactants})$\)

\($\Delta H_1 = [\Delta H_f(K^+(aq)) + \Delta H_f(Cl^-(aq))] - \Delta H_f(KCl(s))$\)

= [-418.8 + (-131)] - (-436.7)

= +113.9 kJ/mol

The positive sign indicates that the dissolution of KCl is an endothermic process. Therefore, energy is absorbed from the surroundings when one mole of KCl dissolves in water.

Now, we need to calculate the enthalpy change for the dilution of the resulting 1M KCl(aq) solution. The enthalpy change for this process can be represented by the following equation:

\(KCl(\text{aq, 1M}) \rightarrow KCl(\text{aq, xM})$ $(2)\)

The enthalpy change for this reaction can be calculated using the equation:

\($\Delta H_2 = q = mC\Delta T$\)

where m is the mass of the solution, C is the specific heat capacity of the solution, and ΔT is the temperature change of the solution upon dilution. Since the temperature change upon dilution is negligible

Using Hess's Law, the standard enthalpy of the solution of KCl can be calculated as:

\($\Delta H_{\text{soln}} = \Delta H_1 + \Delta H_2$\)

= ΔH1 + 0

= +113.9 kJ/mol

Explanation: Avogadro's number is a mole, which concludes that this statement is true.

If more \(H_{2}\) and \(N_{2}\) are added to the reaction 3\(H_{2}\) + N2 → 2\(NH_{3}\) after it reaches equilibrium, two events will occur Shift in Equilibrium and Increased Yield of \(NH_{3}\)

1. Shift in Equilibrium: According to Le Chatelier's principle, when additional reactants are added, the equilibrium will shift in the forward direction to consume the added reactants and establish a new equilibrium. In this case, more \(NH_{3}\) will be produced to counteract the increase in \(H_{2}\) and \(N_{2}\).

2. Increased Yield of \(NH_{3}\): The shift in equilibrium towards the forward reaction will result in an increased yield of \(NH_{3}\). As more \(H_{2}\) and \(N_{2}\) are added, the reaction will favor the production of \(NH_{3}\) to maintain equilibrium. This will lead to an increase in the concentration of \(NH_{3}\) compared to the initial equilibrium state.

It is important to note that the equilibrium position will ultimately depend on factors such as the concentrations of \(H_{2}\), \(N_{2}\), and \(NH_{3}\), as well as the temperature and pressure of the system. By adding more reactants, the equilibrium will adjust to achieve a new balance, favoring the formation of more \(NH_{3}\).

When a system is at equilibrium, the value of ÎSsys is zero, but the surroundings still experience a change in entropy (ÎSsurr) due to the transfer of heat between the system and surroundings. The value of ÎSsurr can be calculated using the formula ÎSsurr = -ÎSsys/T.

When a system is at equilibrium, it means that the rate of the forward and reverse reactions are equal, and there is no net change in the system. At this point, the system and the surroundings are in thermal equilibrium, meaning they are at the same temperature.

In this scenario, the change in entropy of the system (ÎSsys) is equal to zero, as there is no net change in the system. However, the surroundings still experience a change in entropy (ÎSsurr). This is because heat is transferred between the system and surroundings until both reach the same temperature. This transfer of heat results in a change in entropy of the surroundings.

The value of ÎSsurr can be calculated using the formula ÎSsurr = -ÎSsys/T, where T is the temperature at which the system and surroundings are in equilibrium. The negative sign in the equation indicates that the change in entropy of the surroundings is opposite in sign to the change in entropy of the system.

The statement is false. The enzyme concentration at which the reaction velocity is half its maximal value is not the KM. The KM is the substrate concentration at which the reaction velocity is half its maximal value.

The enzyme concentration does not affect the KM. The KM is a measure of the affinity of an enzyme for its substrate. A low KM indicates that the enzyme has a high affinity for its substrate, and therefore requires a lower concentration of substrate to reach half its maximal velocity. A high KM indicates that the enzyme has a low affinity for its substrate, and therefore requires a higher concentration of substrate to reach half its maximal velocity.

The enzyme concentration, on the other hand, affects the maximal velocity of the reaction. A higher enzyme concentration will result in a higher maximal velocity. This is because a higher enzyme concentration means that there are more enzyme molecules available to catalyze the reaction.

The phenomenon observed, where water at the top of the mountain started boiling before the water at lower stations, can be attributed to the difference in atmospheric pressure at various elevations.

Atmospheric pressure decreases with increasing altitude. The pressure exerted by the atmosphere affects the boiling point of a liquid. As the pressure decreases, the boiling point of a substance also decreases.

This is because boiling occurs when the vapor pressure of the liquid equals the atmospheric pressure. When the atmospheric pressure decreases, the vapor pressure required for boiling is reached at a lower temperature.

On top of the mountain, where the atmospheric pressure is lower, the boiling point of water is lower compared to the stations at lower elevations.

Therefore, even if the water at each station was at the same initial temperature, the water at the top of the mountain reached its boiling point first because the lower atmospheric pressure allowed the vapor pressure to be achieved at a lower temperature.

In contrast, the stations located at lower elevations experience higher atmospheric pressure, requiring a higher temperature to reach the boiling point of water. Hence, the water at these stations takes longer to reach the boiling point compared to the water at the top of the mountain.
