The products formed in the acid-base reaction between KOH (potassium hydroxide) and HBr (hydrogen bromide) are potassium bromide (KBr) and water (H2O).

What is Conjugate Base?

A conjugate base is the species that remains after an acid has donated or lost a proton (H+) during a chemical reaction. In other words, it is the species that is formed when an acid loses a hydrogen ion (H+) from its chemical formula.

The products of this reaction, KBr and H2O, are examples of a salt and a neutral compound, respectively. KBr is the conjugate base of the strong acid HBr, and H2O is the conjugate acid of the strong base KOH. The reaction between KOH and HBr results in the formation of a salt, KBr, and water (H2O), through a neutralization reaction.

Answer:

2. 2.74876 + 13.37 +  3. 48640.1

Explanation:

The growth of algae won't cause the pH to fall quickly. As a result, choice C is the right response.

Water bodies that have algae growth may have less clear water, utilize more chlorine, and produce slimy growth on surfaces. Algae use elements like phosphorus and nitrogen, which can upset the water's equilibrium and encourage the growth of hazardous bacteria and other creatures.

Algal decay and death can also lower the oxygen content of the water, which can cause fish deaths and other ecological issues. However, the growth of algae usually does not result in an abrupt pH drop. Acid rain, dissolved minerals and gases, organic matter, and other variables can all reduce pH, however algae growth is not a substantial contributor to pH variations.

The principle of "like dissolves like" is based on the idea that substances with similar polarity or solubility characteristics are more likely to dissolve in each other. In chromatography, the mobile phase and stationary phase are selected based on their relative polarities. The stationary phase is typically a solid or liquid that is polar, while the mobile phase is a liquid that can be either polar or nonpolar.

When a compound is introduced to the mobile phase, it will interact with the solvent molecules in the mobile phase. If the compound has a similar polarity or solubility characteristic to the mobile phase, it will dissolve and move through the column more easily. On the other hand, if the compound has a higher affinity for the stationary phase, it will interact more strongly with the stationary phase and move more slowly through the column.

Therefore, the principle of "like dissolves like" explains the affinity of a compound for the mobile phase relative to the stationary phase in chromatography by highlighting the importance of polarity and solubility in determining which phase a compound will interact with more strongly.

To solve this problem, we can use the ideal gas law, which relates the pressure, volume, number of moles, and temperature of a gas:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature in Kelvin.

We are given:

P1 = 1.88 atm

T1 = 25.0°C = 298.15 K

We need to find P2, given:

T2 = 37.0°C = 310.15 K

We can assume that the volume and number of moles of gas remain constant.

Substituting these values into the ideal gas law equation, we get:

P1V = nRT1

P2V = nRT2

Dividing the second equation by the first equation, we get:

P2/P1 = T2/T1

Substituting the values we have, we get:

P2/1.88 atm = 310.15 K/298.15 K

Solving for P2, we get:

P2 = (1.88 atm) x (310.15 K)/(298.15 K) = 1.96 atm

Therefore, the pressure in the tire will be 1.96 atm if the temperature warms up to 37.0°C.

The pH of the C₆H₅COONa solution at 0.200 M is roughly 2.89, which is the same as response choice (d).

In water, C₆H₅COONa dissociates to form C₆H₅COO⁻ and Na⁺ ions,

C₆H₅COONa ⇌ C₆H₅COO⁻ + Na⁺

The C₆H₅COO⁻ ion can act as a weak base by accepting a proton from water. The Ka of benzoic acid, C₆H₅COOH, is 6.4 × 10⁻⁵. To calculate the pH of a 0.200 M solution of C₆H₅COONa, we need to consider the dissociation of C₆H₅COO⁻ in water. We can assume that the dissociation of water is negligible compared to the dissociation of C₆H₅COO⁻, so we can use the following equation to calculate the concentration of OH⁻ ions,

Kb = Kw/Ka = [OH⁻][C₆H₅COOH]/[C₆H₅COO⁻]

Since Kb × Ka = Kw, we can use the Kb value to calculate the OH⁻ concentration and then use the expression for Kw to calculate the H⁺ concentration and pH,

Kb = [OH⁻][C₆H₅COOH]/[C₆H₅COO⁻]

[OH⁻] = Kb[C₆H₅COO⁻]/[C₆H₅COOH]

= (1.0 × 10⁻¹⁴)/(6.4 × 10⁻⁵ × 0.200)

= 7.81 × 10⁻¹² M

Kw = [H⁺][OH⁻]

= 1.0 × 10⁻¹⁴

[H⁺] = Kw/[OH⁻]

= 1.28 × 10⁻³ M

Molarity = 0.1176 M

b. 30 ml of solution has how many moles

Molarity = moles/volume

0.1176 = moles/0.03

Moles = 0.003528 mol.

c. To determine a fresh solution's molarity:

M₁V₁ = M₂V₂

0.1176 × 0.25 = M₂ × 0.28

0.0294 = 0.28M₂

M₂ = 0.105 M

B) ln[A] vs time. For a second order reaction, the rate law can be written as rate = k[A]². Taking the natural logarithm of both sides yields ln(rate) = ln(k) + 2ln[A].

This can be rearranged to give the linear plot of ln[A] vs time with a slope of 2k and a y-intercept of ln(k). Therefore, the plot that will be linear for a second order reaction is B) ln[A] vs time.

A negative number results from any real integer that is more than 0 but less than 1. The output is zero when the input is 1. And last, any real number that is bigger than 1 leads to a positive number. Therefore, the set of all real numbers bigger than zero is the domain of the natural logarithm function.

We must make advantage of the characteristics of natural logarithmic and natural exponential functions in order to represent a function in terms of these functions.

With e (the natural number) as its base, the natural logarithmic function is represented by the symbol ln(x). E(x) stands for the natural exponential function.

we need to use the concept of stoichiometry.Therefore, we can conclude that 1 mole of Cl2 gas would be produced under standard conditions if 3,000 F are applied to the Downs cell.

The balanced chemical equation shows that 1 mole of Cl- reacts to produce 1/2 mole of Cl2 gas. This means that if we have 2 moles of Cl-, we can produce 1 mole of Cl2 gas.
We are given that 3,000 F is applied to the Downs cell, which is considered standard conditions. At standard conditions, 1 mole of any gas occupies a volume of 22.4 L. Therefore, we can calculate the number of moles of Cl2 gas produced using the ideal gas law:
PV = nR
where P is the pressure (1 atm at standard conditions), V is the volume (22.4 L per mole of gas), n is the number of moles, R is the gas constant (0.0821 L*atm/mol*K), and T is the temperature (in Kelvin, which is (273 + 1500) = 1773 K for 3,000 F).
Rearranging the equation to solve for n, we get:
n = PV/RT = (1 atm)(22.4 L)/(0.0821 L*atm/mol*K)(1773 K) = 1.00 moles of gas
we need to use the concept of stoichiometry.Therefore, we can conclude that 1 mole of Cl2 gas would be produced under standard conditions if 3,000 F are applied to the Downs cell.

Collisions among gas molecules or impacts with the container's walls are completely elastic. If a gas molecule collides against something else or the container's walls, none of its energy is wasted.

Gases is made up of particles (the molecules or atom) that are constantly moving at random. Gas particles are continually clashing with one another and with the container's walls. These collisions are elastic, which means that there is no net loss in energy as a result of the impacts.

Gas particles move quickly in all directions, regularly hitting with one other and the container's side. The particles gather momentum and accelerate rapidly as temperature raises.
