The volume of 0.415 M silver nitrate needed to precipitate all the bromide in 35.0 mL of 0.128 M calcium bromide is 5.41 mL.

There are different ways to approach stoichiometry problems, but one common method is to use the balanced chemical equation, the molar ratios, and the concentration-volume relationships.

The balanced chemical equation for the precipitation reaction between silver nitrate and calcium bromide:AgNO3(aq) + CaBr2(aq) → AgBr(s) + Ca(NO3)2(aq)

Determine the limiting reactant and the theoretical yield of silver bromide.

Use the molar mass of AgBr to convert its moles to grams or volume of the precipitate.

The moles of calcium bromide:moles of CaBr2 = concentration × volume (in liters)moles of CaBr2 = 0.128 mol/L × 0.035 Lmoles of CaBr2 = 0.00448 mol

Use the molar ratio between CaBr2 and AgNO3 to find the moles of AgNO3 needed to react with all the bromide ions.

moles of AgNO3 = moles of CaBr2 × (1 mol AgNO3/1 mol CaBr2)moles of AgNO3 = 0.00448 mol × (1 mol AgNO3/2 mol Br-)moles of AgNO3 = 0.00224 mol

Since the stoichiometry of the reaction is 1:1 for AgBr and AgNO3, the theoretical yield of AgBr is also 0.00224 mol.

The volume of 0.415 M AgNO3 needed to provide the theoretical yield of AgBr.

Use the concentration-volume relationship to find the volume of AgNO3 that contains the same amount of moles as the theoretical yield of AgBr.

Moles of AgNO3 = 0.00224 molvolume of AgNO3 = moles of AgNO3/concentration of AgNO3volume of AgNO3 = 0.00224 mol/0.415 mol/Lvolume of AgNO3 = 0.00541 L or 5.41 mL

Therefore, the volume of 0.415 M silver nitrate needed to precipitate all the bromide in 35.0 mL of 0.128 M calcium bromide is 5.41 mL.

The best choice to favor elimination over substitution in a reaction with 2-bromopropane is sodium tert-butoxide. This is because this reagent is a stronger base, allowing for the deprotonation of 2-bromopropane.

The reaction of 2-bromopropane most favors elimination over substitution when reacted with the sodium tert-butoxide favors elimination over substitution in a reaction with 2-bromopropane.

In organic chemistry, substitution reaction occurs when an atom or a group of atoms in a molecule is replaced by another atom or a group of atoms. In contrast, elimination reactions occur when atoms or groups of atoms are removed from a molecule. The most significant difference between the two is that one leaves another behind. This means that if one group is substituted by another, then it results in a completely different compound than before.

In the reaction between 2-bromopropane and sodium tert-butoxide, the sodium tert-butoxide (Na + OC(CH3)3) serves as a strong base. The tert-butoxide ion, as a strong base, abstracts a hydrogen ion from a carbon adjacent to the bromine, leading to the formation of a reactive alkene intermediate.

The elimination of HBr from 2-bromopropane to form propene is made possible by this alkene intermediate. Therefore, the reaction most favors elimination over substitution when reacted with sodium tert-butoxide.

To determine the percent yield, we need to first calculate the theoretical yield of the reaction using stoichiometry, and then divide the actual yield by the theoretical yield and multiply by 100%. The percent yield of the reaction is approximately 84.9%.

Percent yield is a measure of the efficiency of a chemical reaction, calculated by dividing the actual yield of a reaction by the theoretical yield and multiplying by 100%. It represents the percentage of the theoretical amount of product that was actually obtained in a reaction.

The balanced chemical equation is:

2Al + Cr₂O₃ → Al₂O₃ + 2Cr

The molar mass of Cr₂O₃ is 152 g/mol, the molar mass of Al is 27 g/mol, and the molar mass of Cr is 52 g/mol.

We need to determine which reactant is limiting, so we can calculate the theoretical yield based on the amount of limiting reactant. We can do this by calculating the number of moles of each reactant using their molar masses and dividing by their stoichiometric coefficients in the balanced equation:

moles of Cr₂O₃= 44.1 g / 152 g/mol = 0.29 mol

moles of Al = 35.0 g / 27 g/mol = 1.30 mol

From the balanced equation, we see that 1 mole of Cr2O3 reacts with 2 moles of Cr. Therefore, the theoretical yield of Cr is:

moles of Cr produced = 0.29 mol Cr₂O₃x (2 mol Cr / 1 mol Cr₂O₃) = 0.58 mol Cr

mass of Cr produced = 0.58 mol Cr x 52 g/mol = 30.16 g Cr

The percent yield is:

% yield = (actual yield / theoretical yield) x 100%

% yield = (25.6 g Cr / 30.16 g Cr) x 100% = 84.9%

Kc = [C]^c[D]^d/[A]^a[B]^b

where [ ] denotes the molar concentration of the respective species. a, b, c, and d are the coefficients of the balanced chemical equation for the species A, B, C, and D.

If a chemical reaction is at equilibrium at a given temperature, the concentration of reactants and products remains constant over time. In other words, the rate of the forward reaction and the rate of the reverse reaction is equal.

The reaction for which we need to find the equilibrium constant is:-

HI(g)  ↔ H(g) + I(g)

Now, assume that initially there were 'x' moles of HI in the reaction mixture. After the dissociation of HI, the concentration of H and I will be equal to 'x - y' moles. The concentration of HI will be equal to 'x - y' moles.

Here, y is the number of moles of HI that dissociated. According to the given statement, HI is 40% dissociated. Therefore, the number of moles of HI that dissociated will be 0.4x. Similarly, the number of moles of H and I that will be formed will also be 0.4x.

The equation for the dissociation of HI can be written as:-

HI(g)  ↔ H(g) + I(g)

The initial number of moles = x Moles dissociated = 0.4x

At equilibrium, the number of moles of HI = x - 0.4x = 0.6x

Number of moles of H = 0.4x

Number of moles of I = 0.4x

Finally, substitute these values in the expression for the equilibrium constant:-

Kc = [H][I]/[HI]

Kc = (0.4x)(0.4x)/(0.6x)²

Kc = 0.16/0.36Kc = 0.4444 (approximately)

Therefore, the equilibrium constant Kc for the given reaction is 0.4444 (approximately).

The following steps can be used to determine the pH of the solution.

Phosphoric acid is a triprotic acid, which means that it can donate three hydrogen ions (H+) to a solution. Phosphoric acid's first dissociation reaction is as follows:

H3PO4(aq) → H+(aq) + H2PO4-(aq) This means that in water, H3PO4 will donate one hydrogen ion (H+) to the solution, leaving behind the negatively charged H2PO4- ion.

To determine the pH of the solution, we can use the formula:

pH = -log[H+]

First, we need to determine the concentration of H+ ions in the solution, which we can find from the dissociation of H3PO4. H3PO4(aq) → H+(aq) + H2PO4-(aq) Initially, the concentration of H3PO4 is 0.138 M. Since we're assuming complete dissociation for the sake of this example, we can say that 100% of the H3PO4 dissociates into H+ and H2PO4-.

This means that the concentration of H+ in the solution is equal to the initial concentration of H3PO4:0.138 MWe can now substitute this value into the pH formula:

pH = -log[H+]pH = -log[0.138]pH = 1.49

To calculate the mass % of the solution, we have to calculate the mass of the solution first.

Step-by-step explanation:

The formula for density is given by:

Density = Mass/Volume

Or,

Mass = Density × Volume

Now, we will calculate the mass of the solution.

Mass = Density × Volume

        = 1.06 × 895= 948.7 g

Now, we will calculate the mass % of the solution.

Mass % = (Mass of solute/Total mass of solution) × 100

Mass of solute = 99.7 g

Total mass of solution = 948.7 g

Mass % = (99.7/948.7) × 100

             = 10.51%

Therefore, the mass % of the solution is 10.51%.
