To balance the chemical equation: NaPO3 + Ba(NO2)2 → Ba(PO3)2 + NaNO2. substituting a = c into the third equation: a = c From the fourth equation, we have: 3a = 2c + 2a 3a = 2a + 2a a = 0.

We can set up a system of equations based on the number of atoms of each element on both sides of the equation. Let's denote the coefficients of the balanced equation as follows:

NaPO3: a

Ba(NO2)2: b

Ba(PO3)2: c

NaNO2: d

Now, we can write the system of equations:

Na: a = d

Ba: b = c

P: a = c

O: 3a = 2c + 2d

N: 2b = d

Solving this system of equations will give us the balanced coefficients. From the first equation, we can substitute d = a into the fifth equation:2b = a Substituting this back into the second equation: b = c Now, substituting a = c into the third equation: a = c From the fourth equation, we have: 3a = 2c + 2a 3a = 2a + 2a a = 0

Explanation:

In a liquid-liquid extraction (LLE) system with loratadine and pseudoephedrine sulfate, the choice of organic and aqueous phases is crucial for efficient separation.

Loratadine is a non-polar compound, while pseudoephedrine sulfate is more polar due to the presence of a sulfate group. To achieve effective separation, we need to choose a suitable organic phase and aqueous phase.

For the organic phase, a non-polar solvent such as diethyl ether, ethyl acetate, or chloroform can be used. These solvents have good solubility for loratadine. The non-polar organic phase will extract loratadine from the mixture, allowing for separation from the aqueous phase.

As for the aqueous phase, we need to choose a polar solvent that will selectively extract pseudoephedrine sulfate. Aqueous solutions of acids like hydrochloric acid (HCl) or sulfuric acid (H2SO4) can be used. The acidic conditions protonate the pseudoephedrine sulfate, making it more soluble in the aqueous phase.

To perform the extraction, the mixture of loratadine and pseudoephedrine sulfate is added to the LLE system consisting of the organic phase (non-polar solvent) and the aqueous phase (acidic solution). The mixture is then vigorously shaken to ensure thorough mixing and extraction.

After shaking, the phases are allowed to separate, with the more dense aqueous phase settling at the bottom and the less dense organic phase on top. The layers can be carefully separated, and each phase can be further processed to isolate the desired compounds.

Answer:

Final pressure of the air inside is 0.83atm

Explanation:

Boyle's law is the gas law that relates the change in volume when pressure change at constant temperature and vice versa. The equation is:

P₁V₁ = P₂V₂

Where P is pressure and V is volume of 1, initial state and 2, final state of the gas

Replacing:

P₁ = 0.5atm

V₁ = 2.5L

P₂ = ?

V₂ = 1.5L

P₁V₁ = P₂V₂

0.5atm*2.5L = P₂*1.5L

0.83atm = P₂

The concentration 103 g \(KCl\) in 628 g \(H_2O\) is 14.1% by mass

The concentration 30. 3 mg \(KNO_3\) in 9. 29 g \(H_2O\) is 0.325% by mass.

The concentration 9. 18 g \(C_2H_6O\) in 72. 2 g \(H_2O\) is 11.3% by mass.

To calculate the concentration of a solution in mass percent, we need to determine the mass of the solute and the mass of the solution. The mass percent is then calculated as:

Mass percent = (Mass of solute / Mass of solution) x 100%

Part A:

Mass of \(KCl\)= 103 g

Mass of \(H_2O\) = 628 g

Mass of solution = Mass of \(KCl\) + Mass of \(H_2O\) = 103 g + 628 g

                                                                              = 731 g

Mass percent of \(KCl\) = (103 g / 731 g) x 100% = 14.1%

Therefore, the concentration of the \(KCl\) solution is 14.1% by mass.

Part B:

Mass of \(KNO_3\) = 30.3 mg = 0.0303 g

Mass of \(H_2O\) = 9.29 g

Mass of solution = Mass of \(KNO_3\) + Mass of \(H_2O\) = 0.0303 g + 9.29 g

                                                                                 = 9.3203 g

Mass percent of \(KNO_3\) = (0.0303 g / 9.3203 g) x 100%

                                       = 0.325%

Therefore, the concentration of the \(KNO_3\) solution is 0.325% by mass.

Part C:

Mass of \(C_2H_6O\) = 9.18 g

Mass of \(H_2O\) = 72.2 g

Mass of solution = Mass of \(C_2H_6O\) + Mass of \(H_2O\) = 9.18 g + 72.2 g

                                                                                   = 81.38 g

Mass percent of \(C_2H_6O\) = (9.18 g / 81.38 g) x 100%

                                       = 11.3%

Therefore, the concentration of the \(C_2H_6O\) solution is 11.3% by mass.

Answer:

Explanation:

The central atom in SO₂ is sp2 hybridized. In SO₂, the central atom is sulfur (S).

To determine the hybridization of the central atom, we need to examine the electron configuration and the number of electron domains around the central atom.

Sulfur has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁴. The valence shell of sulfur consists of three electron domains: two sigma bonds with oxygen atoms and one lone pair of electrons.

To accommodate the three electron domains, sulfur undergoes hybridization. The electron domains are mixed to form new hybrid orbitals that are directed towards the corners of a trigonal planar geometry.

Since there are three electron domains involved in the hybridization, the sulfur atom is sp2 hybridized. The three hybrid orbitals are formed by combining one s orbital and two p orbitals.

Overall, the sp2 hybridization of sulfur in SO₂ allows for the formation of three sigma bonds and results in a trigonal planar molecular geometry.

At time = 1, one of the H₂ molecules has reacted, producing one molecule of HI. This means that there are now 0.5 moles of H₂, 0.5 moles of I₂, and 1 mole of HI in the container.

At time = 3, the reaction has reached equilibrium. This means that the concentrations of all three gases have stabilized. Without additional information about the reaction conditions and equilibrium constants, we cannot determine the exact concentrations of each gas at equilibrium.

Between time = 1 and time = 2, the forwards reaction (H₂ + I₂ → 2HI) is favored because one of the H₂ molecules has reacted to produce HI. This means that the concentration of H₂ has decreased while the concentration of HI has increased, driving the reaction forwards according to Le Chatelier's principle.

1) The reaction is exothermic and heat is a product

2) The color would turn to pink.

Let us recall that an endothermic reaction is one in which the increase in the temperature of the system would drive the forward reaction. This implies that the equilibrium would shift to the right when the set up is heated. Since the color of the solution changes to blue when heated hence the reaction is exothermic.

If you removed heat by placing the solution in the ice bath, we can see that we have removed the heat thus we expect that the reverse reaction would take place and the color would change to pink.

Answer:

The atoms are pulled together by attractive forces and become more organized.

Explanation:

According to the gas laws, the temperature is the measure of the average kinetic energy of the atoms of a molecule. State of change is primary driven by energy gain or loss. When molecules absorb energy, they transit into a phase in which their atoms are more mobile and move about more freely, staying relatively from, one from the other. When there is loss of energy, the molecules change into a less mobile state in which their atoms  move with lesser energy, and stay relatively closer to each other than they were.

During a the process in which atoms lose energy, its atoms are pulled together by the attractive force, and become more organised, since they now possess less kinetic energy.

We find the limiting reactant from the ratio of the mole and the reaction coefficient

Fe ⇒ 3.9 : 4 = 0.975

O ⇒ 4.7 : 3 = 1.56

Because the ratio of Fe is smaller, then Fe becomes the limiting reactant

Explanation:

If the zero is located in the RHP and the poles are located in the LHP, it is possible that the process will exhibit an inverse response based on the transfer function G(s) = K(Tzs + 1) / ((115 + 1)(T25 + 1)).

To determine when the process will possess an inverse response based on the given transfer function G(s) = K(Tzs + 1) / ((115 + 1)(T25 + 1)), we need to analyze the characteristics of the transfer function.

In a transfer function, an inverse response occurs when the sign of the phase angle changes by 180 degrees or π radians as the frequency increases. Mathematically, this corresponds to a pole and a zero that are located in the right-half plane (RHP) of the complex plane.

From the given transfer function G(s) = K(Tzs + 1) / ((115 + 1)(T25 + 1)), we can observe the following:

The numerator of the transfer function has a single zero, which is given by (Tzs + 1).

The denominator of the transfer function has two poles, which are given by ((115 + 1)(T25 + 1)).

To determine the location of the poles and zeros, we need specific values for T, z, and K. Without those values, we cannot determine the exact location of the poles and zeros or whether they lie in the RHP.

However, in general, if the zero (Tzs + 1) is located in the RHP and the poles ((115 + 1)(T25 + 1)) are located in the left-half plane (LHP), the transfer function may possess an inverse response. The presence of a pole in the RHP and a zero in the LHP can lead to an inverse response behavior.
