The correct choice is A) −5Δ[Br−]/Δt. The rate expressed as Δ[Br2]/Δt is proportional to -5 times the rate of change of Br−.

In the given reaction 5Br−(aq) + BrO3−(aq) + 6H+(aq) → 3Br2(aq) + 3H2O(aq), the stoichiometric coefficients provide information about the relationship between the reactants and products. To determine the rate expressed as Δ[Br2]/Δt, we need to compare it with the rate of change of the other species.

Based on the balanced equation, for every 5 moles of Br− consumed, 3 moles of Br2 are produced. Therefore, the rate of change of Br−, Δ[Br−]/Δt, is related to the rate of change of Br2, Δ[Br2]/Δt, by a factor of -5/3.

The other choices, B) −0.6Δ[Br−]/Δt, C) 3Δ[BrO3−]/Δt, and D) −Δ[H2O]/Δt, do not correspond to the correct relationship based on the stoichiometric coefficients of the reaction. Therefore, the correct answer is A) −5Δ[Br−]/Δt.

The curve will have the points (0, 8.04), (halfway, 8.04), (equivalence point, 8.04), and (endpoint, 14). The points can then be connected to create a graph of the pH over the course of the titration.

At the start of the titration, before any KOH has been added, the concentration of HBrO is 0.200 M and the concentration of KOH is 0.000 M, so the pH can be calculated as:

pH = 8.04 + log ([0.000]/[0.200]) = 8.04 + log (0) = 8.04.

When the equivalence point is reached, the concentrations of the two reactants are equal, so the pH can be calculated as:

pH = 8.04 + log ([0.200]/[0.200]) = 8.04 + log (1) = 8.04.

At the end of the titration, when all of the KOH has been added, the concentration of KOH is 0.140 M and the concentration of HBrO is 0.000 M, so the pH can be calculated as:

pH = 14 + log ([0.140]/[0.000]) = 14 + log (infinity) = 14.

Using these four points, a titration curve can be drawn to represent the pH of the solution throughout the titration. The curve will have the points (0, 8.04), (halfway, 8.04), (equivalence point, 8.04), and (endpoint, 14). The points can then be connected to create a graph of the pH over the course of the titration.

Answer:

90.126g

Explanation:

I am going to assume that the equation is supposed to say SiO2.

We want to calculate the number of grams in 1.50 moles of SiO2.

First we must find the molecular mass of SiO2

Looking at a periodic table, the mass of Silicon(Si) is 28.086g and the mass of Oxygen(O) is 15.999g

Using this, the mass of SiO2 would be 28.086 + 15.999(2) = 60.084g

Now we can use dimensional analysis to find the number of grams in 1.50 moles of SiO2

The table created should look something like \(\frac{1.50molSiO_2}{}*\frac{60.084g}{1molSiO2}\)

the molSiO2 cancel out and we get

\(1.5*\frac{60.085g}{1}\) = 90.126g

So there are 90.126g of SiO2 in 2 moles of SiO2

0.0080 grams are in 0.89 moles of CaCI₂.

The mole (M) is defined as it contain exactly 6.023 × 10²³ elementary entities present in it. 1 mole is exactly equal to the 6.023 × 10²³ elementary entities.

We can solve the above problem as follows;

So,

1 Mole of substance = Molar mass of the substance.

The given compound named is Calcium Chloride.

Then,

Molar mass of Calcium chloride = 1 mole

Molar mass of CaCl₂ = 40 + 2 × 35.4

= 110.9g/mol

Therefore,

110.9 grams of CaCl₂ = 1 mole

1 gram of CaCl₂ = 1 / 110.9

0.89 grams of CaCl₂

= 1 / 110 ×  0.89

= 0.0080 grams

Explanation:

The molarity of the KOH solution is 1.6 M.

Hence, the correct answer is option (b).

To determine the molarity of KOH (potassium hydroxide), we can use the stoichiometry of the balanced chemical equation for the reaction between HBr (hydrobromic acid) and KOH.

The balanced equation for the reaction is:

HBr + KOH -> KBr + H₂O

From the equation, we can see that the stoichiometric ratio between HBr and KOH is 1:1. This means that for every 1 mole of HBr, we need 1 mole of KOH.

Given:

Volume of HBr (VHBr) = 4.00 mL

Molarity of HBr (MHBr) = 2.5 M

Volume of KOH (VKOH) = 6.25 mL

To find the molarity of KOH, we can use the equation:

MHBr x VHBr = MKOH x VKOH

Plugging in the values:

(2.5 M) x (4.00 mL) = MKOH x (6.25 mL)

Solving for MKOH:

MKOH = (2.5 M x 4.00 mL) / 6.25 mL

MKOH = 10.0 / 6.25

MKOH = 1.6 M

Therefore, the molarity of the KOH solution is 1.6 M.

The correct answer is (b). 1.6 M.

Answer:

0.324

Explanation:

The following data were obtained from the question:

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

The balanced equation for the reaction is given below:

2NH3 <==> 3H2 + N2

The equilibrium constant, Kc for a given reaction is the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient. Thus, the equilibrium constant for the above reaction can be obtained as illustrated below:

Kc = [H2]³ [N2] / [NH3]²

Concentration of NH3, [NH3] = 0.25 M

Concentration of H2, [H2] = 0.3 M

Concentration of N2, [N2] = 0.75 M

Equilibrium constant (Kc) =.?

Kc = [H2]³ [N2] / [NH3]²

Kc = [0.3]³ × [0.75] / [0.25]²

Kc = (0.027 × 0.75) / 0.0625

Kc = 0.02025 / 0.0625

Kc = 0.324

Therefore, the equilibrium constant for the reaction is 0.324

If 0.01 mol of neon gas at a particular temperature and pressure occupies a volume of 0.225 L, then 0.05 mol of neon gas would occupy a volume of 1.125 L under the same conditions.

Given:

Number of moles of neon gas (n₁) = 0.01 mol

Volume of neon gas (V₁) = 0.225 L

We are required to find the volume of neon gas (V₂) when the number of moles (n₂) is 0.05 mol under the same conditions.

The relationship between the number of moles, volume, and pressure of a gas is given by the ideal gas law: PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.

Since the temperature and pressure are the same in this case, we can rearrange the ideal gas law equation to solve for the volume:

V = (n₁ * V₁) / n₂

Substituting the given values into the equation:

V₂ = (0.01 mol * 0.225 L) / 0.05 mol

V₂ = 0.00225 L / 0.05 mol

V₂ = 0.045 L/mol

Therefore, 0.05 mol of neon gas would occupy a volume of 1.125 L under the same conditions.

Resonance forms are equivalent in contribution: Resonance forms contribute equally to the overall structure of the molecule. They are different representations of the same molecule, with the actual structure being an average or hybrid of the resonance forms.

Resonance forms are different Lewis structures that represent the same molecule but with varying electron distributions. They are denoted by double-headed arrows between the different forms.
