Here is a MATLAB code that calculates and plots the concentration profiles of NH ₃, NH₄+, NO₂-, and NO₃- as a function of time at T=298 K and neutral pH, given the rate constants and initial concentrations:

```matlab

% Rate constants (k) and initial concentrations ([C])

k1 = 0.1;   % Rate constant for NH₃ + H₂O₂ -> NH₂ + H₂O

k2 = 0.05;  % Rate constant for NH₂ + NO₃- -> NO₂- + H₂O

k3 = 0.08;  % Rate constant for NO₂- -> NO₃- + N₂

C_NH₃ = 1.0;    % Initial concentration of NH₃

C_H2₂O₂ = 0.5;   % Initial concentration of H₂O₂

C_NH₄ = 0.0;    % Initial concentration of NH₄+

C_NO₂ = 0.0;    % Initial concentration of NO₂-

C_NO₃ = 0.0;    % Initial concentration of NO₃-

% Time vector

t = 0:0.1:10;   % Time range from 0 to 10 with a step size of 0.1

% Calculation of concentrations at each time point

for i = 1:length(t)

   NH₃(i) = C_NH₃ * exp(-k1*t(i));

   NH₄(i) = C_NH₃ - NH₃(i);

   NO₂(i) = C_NO₂ + k₂ * (NH₄(i) - C_NH₄) * t(i);

   NO₃(i) = C_NO₃ + k₃ * NO₂(i) * t(i);

end

% Plotting concentration profiles

plot(t, NH₃, 'r-', t, NH₄, 'g-', t, NO₂, 'b-', t, NO₃, 'm-');

xlabel('Time');

ylabel('Concentration');

legend('NH₃', 'NH₄+', 'NO₂-', 'NO₃-');

```

The provided MATLAB code calculates and plots the concentration profiles of NH₃, NH₄+, NO₂-, and NO₃- as a function of time based on the given rate constants and initial concentrations. The code uses a time vector to define the time range for which the concentrations will be calculated.

Inside the for loop, the concentrations of NH₃, NH₄+, NO₂-, and NO₃- are calculated at each time point using the given rate constants and the previous concentrations. The concentration of NH₃ decreases exponentially over time due to the reaction NH₃ + H₂O₂ -> NH₂ + H₂O, where k1 is the rate constant. NH₄+ concentration is the difference between the initial NH₃ concentration and the current NH₃ concentration.

The concentration of NO₂- increases with time due to the reaction NH₂ + NO₃- -> NO₂- + H₂O, where k₂ is the rate constant. The change in NH₄+ concentration from its initial value is multiplied by k₂ and the time to calculate the increase in NO₂- concentration.

Finally, the concentration of NO₃- increases with time due to the reaction NO₂- -> NO₃- + N₂, where k₃ is the rate constant. The previous NO₂- concentration is multiplied by k₃ and the time to determine the increase in NO₃- concentration.

The resulting concentration profiles are then plotted using the plot function, with time on the x-axis and concentration on the y-axis. Each compound is represented by a different color line in the plot.

Explanation:

In a cell created using palladium and aluminum, the anode is Aluminum and the cathode is Palladium. This can be determined by oxidation and reduction.

The anode is where oxidation occurs, leading to the loss of electrons. Aluminum tends to undergo oxidation more readily than palladium. Therefore, aluminum would be the anode in this cell. The cathode is where reduction occurs, involving the gain of electrons. Palladium, being less reactive than aluminum, would be the site for a reduction in this cell. Therefore, palladium would be the cathode.

the final volume of air in the balloon  when the balloon is taken to a depth of 10ft in a swimming pool, where the pressure is 981 torr is 10.8 L. Answer: d) 10.8 L.

We are given the initial volume of air in the balloon, Vi = 14.0 L. The initial pressure, Pi = 760 torr. The final pressure, Pf = 981 torr. The depth of the swimming pool, h = 10 ft. The temperature of the air, T is constant, which means that the gas in the balloon is an ideal gas.

We can use Boyle's law and the pressure difference to find the final volume of air.Boyle's law states that at a constant temperature, the volume of a gas is inversely proportional to its pressure. That is,V_1/P_1 = V_2/P_2where V1 and P1 are the initial volume and pressure, and V2 and P2 are the final volume and pressure.

Rearranging this equation, we getV_2 = V_1 × P_1/P_2= 14.0 L × (760 torr)/(981 torr)= 10.8 L

Therefore, the final volume of air in the balloon is 10.8 L. Answer: d) 10.8 L.

Explanation:

Bottom line: Most asteroids are rocky bodies that lie within the asteroid belt while comets are dirty snowballs from the Oort Cloud, with some objects acting like a hybrid of these two types.

In the given scenario, the order of activity from most active to least active is zinc, iron and lead.

The activity of an element in a chemical reaction is determined by its ability to participate in the formation of a compound. In this case, zinc is replacing both iron and lead, meaning it is more active than both of those elements and considered to be the most active element. Iron is only replacing lead, making it less active than zinc but more active than lead.

Lead is the only element that is being replaced, making it the least active element among the three. This order of activity is based on the relative ability of these elements to participate in chemical reactions and form compounds.

In the process of glycolysis, glucose is cleaved into a pair of three-carbon molecules called pyruvate.

Glycolysis is the metabolic pathway that converts glucose into pyruvate. It is a series of reactions that occur in the cytoplasm of the cell and is the first step in both aerobic and anaerobic respiration. In glycolysis, glucose is converted into two molecules of pyruvate. The process involves the use of two ATP molecules and produces a net gain of two ATP molecules, along with two NADH molecules.

The conversion of glucose to pyruvate occurs in ten steps, with each step catalyzed by a specific enzyme. The first five steps require energy in the form of ATP, while the last five steps generate ATP. The end product of glycolysis, pyruvate, is a key intermediate in many metabolic pathways. In aerobic respiration, pyruvate is further oxidized to acetyl CoA, which enters the citric acid cycle. In anaerobic respiration, pyruvate is converted to lactate or ethanol, depending on the organism.

Solubility of \(CaF$_2$\) at 25°C with Ksp of 4.0 x \(10$^{-11}$\) is approximately 6.34 x \(10$^{-4}$\) mol/L.

The dissolvability of a substance is characterized as the most extreme measure of the substance that can break up in a given dissolvable at a specific temperature and strain. The dissolvability of calcium fluoride \((CaF$_2$)\) at 25°C can be determined utilizing its Ksp esteem, which is 4.0 x \(10$^{-11}$\).The Ksp articulation for \(CaF$_2$\) is:

Ksp = \([Ca$^{2+}$][F$^{-}$]$^2$\)

Let the dissolvability of \(CaF$_2$\) be addressed by the variable x, so the convergences of \(Ca$^{2+}$\) and \(F$^{-}$\) in arrangement will be equivalent to x.Subbing these qualities into the Ksp articulation gives:

Ksp = \(x$\times$x$^2$ = x$^3$\)

Reworking the condition gives:

x = \((Ksp)$^{1/3}$\)

Subbing the worth of Ksp = 4.0 x \(10$^{-11}$\) into the above condition gives:x = \((4.0 x 10$^{-11}$)$^{1/3}$ = 6.34 x 10$^{-4}$\) mol/L

In this manner, the dissolvability of calcium fluoride at 25°C is around 6.34 x \(10$^{-4}$\) mol/L, adjusted to two decimal spots for comfort. This really intends that at harmony, 6.34 x \(10$^{-4}$\) moles of calcium fluoride can break up in one liter of water at 25°C.

On the off chance that how much \(CaF$_2$\) in arrangement is higher than this worth, it will encourage out of the arrangement, and assuming it is lower, more \(CaF$_2$\) will break down until the balance focus is reached.

The answer is true. The amount of water vapor that air can hold increases as the temperature increases. Warm air can hold more moisture than cold air.

This is why warm, humid days can feel more uncomfortable than cooler, drier days. When air reaches its saturation point, it can no longer hold any more water vapor, which can lead to precipitation such as rain or snow. Understanding the relationship between temperature and the capacity of air to hold water vapor is important in meteorology, agriculture, and other fields that rely on weather forecasting. It is also relevant in everyday life, as it can impact our comfort and safety in various environments.

The boiling point of water is dependent on the pressure exerted on the liquid. In this case, water boils at 90°C when the pressure exerted on the liquid equals 101.3 kPa, which is equivalent to atmospheric pressure. At different pressures, the boiling point of water will vary.

The boiling point of a substance is the temperature at which its vapor pressure equals the external pressure exerted on the liquid. When the external pressure is equal to the vapor pressure, the liquid starts to vaporize and boil.

In the given options, the pressure values are provided, and we need to determine which pressure corresponds to the boiling point of water at 90°C.

At standard atmospheric conditions, the pressure is approximately 101.3 kPa, which is equivalent to 1 atmosphere (atm) or 760 mmHg. This is also known as the normal boiling point of water, where water boils at 100°C.

Based on this information, we can conclude that option (3) 101.3 kPa is the correct choice. At this pressure, water boils at 90°C.
Therefore, the boiling point of water is affected by the pressure exerted on the liquid, and at 101.3 kPa, water boils at 90°C. At higher pressures, such as option (4) 120 kPa, water would boil at a higher temperature, and at lower pressures, such as options (1) 65 kPa or (2) 90 kPa, water would boil at a lower temperature.
