Answer: 9.46

Explanation: in LiOH solution concentration of OH- ions is 2.88·10^-5 M

And pOH = -log( 2.88·10^-5 M) = 4.54. Because PH + pOH = 14.00

Then pH = 14-4.54

Explanation:

Answer:

Explanation:

Mg²⁺ is divalent , hence

Molecular weight / 2 = equivalent weight .

.25 moles = 2 x .25 equivalents = .5 equivalents .

Cl⁻ is monovalent so

molecular weight = equivalent weight

.50 mole = .50 equivalent

Total equivalent = .50 of Mg²⁺ + .50 of Cl⁻

= 1 equivalent .

=0.3529moles

According to the mole concept, the number of moles of molecules in a 12.0-gram sample of Cl₂ is equal to 0.169  moles.

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass  in grams present in one mole  of atoms is its atomic mass.Number of moles is mass/molar mass= 12/70.90=0.169 moles.

Answer:

a. changes with temperature.

Explanation:

Hello there!

In this case, according to the thermodynamic definition of the equilibrium constant in terms of the Gibbs free energy of reaction and the temperature of the system:

[tex]lnK=-\frac{\Delta G}{RT}[/tex]

It is possible to figure out that the equilibrium constant varies as temperature does, not only on the aforementioned definition, but also in the Gibbs free energy as it is also temperature-dependent. Therefore, the appropriate answer is a. changes with temperature.

Answer:

phase change always has two phases in contact during the change. melting => solid & liquid; evaporation (boiling) => liquid & vapor. If only one phase is present, then phase change is not occurring. Also, when two phases are in contact, no temperature changes occur. Only the pure phase demonstrates temperature change when measured. Example, when ice is added to water, at thermal equilibrium (temp = 0°C) the water temp will not continue to change. Only when all the ice has melted will the water temperature demonstrate a measured temperature change.

Kinetic energy is the amount of energy present in the object due to motion. It is required by the body for action and motion. The kinetic energy of the car is 34385J.

Kinetic energy is a type of energy that is directly proportional to the mass of the object and the square of the velocity. The formula for the kinetic energy can be given as,

[tex]\rm KE = \dfrac{1}{2}mv^{2}[/tex]

Here,

Mass of the car (m) = 130 kg

Velocity of the car (v) = 23 m/s

Substituting values in the equation:

[tex]\begin{aligned}\rm KE &= \dfrac{1}{2}\rm mv^{2}\\\\&= \dfrac{1}{2}\times 130\times (23)^{2}\\\\&= 34385\;\rm J\end{aligned}[/tex]

Therefore, 34385J is the kinetic energy of the car.

The statement which is TRUE about limiting and excess reactants is (B) The limiting reactant determines the maximum amount of product that can be formed.hence the correct option is (B)

A reactant that is completely consumed at the end of a chemical reaction is known as the limiting reagent.

Since the reaction cannot proceed without this reagent, the amount of product that can be produced is constrained.

The reactant that is totally consumed during a reaction, or the limiting reagent, decides when the process comes to an end.

The precise quantity of reactant required to react with another element can be estimated from the reaction stoichiometry.

Your answer is 26.7  Pretty sure

Explanation: (study)

Answer:

Work is all on the paper

The question is incomplete. The complete question is :

A common "rule of thumb" for many reactions around room temperature is that the rate will double for each ten degree increase in temperature. Does the reaction you have studied seem to obey this rule? (Hint: Use your activation energy to calculate the ratio of rate constants at 300 and 310 Kelvin.)

Solutions :

If we consider the activation energy to be constant for the increase in 10 K temperature. (i.e. 300 K → 310 K), then the rate of the reaction will increase. This happens because of the change in the rate constant that leads to the change in overall rate of reaction.

Let's take :

[tex]$T_1=300 \ K$[/tex]

[tex]$T_2=310 \ K$[/tex]

The rate constant = [tex]$K_1 \text{ and } K_2$[/tex] respectively.

The activation energy and the Arhenius factor is same.

So by the arhenius equation,

[tex]$K_1 = Ae^{-\frac{E_a}{RT_1}}$[/tex]  and [tex]$K_2 = Ae^{-\frac{E_a}{RT_2}}$[/tex]

[tex]$\Rightarrow \frac{K_1}{K_2}= \frac{e^{-\frac{E_a}{RT_1}}}{e^{-\frac{E_a}{RT_2}}} $[/tex]

[tex]$\Rightarrow \frac{K_1}{K_2}= e^{-\frac{E_a}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)}$[/tex]

[tex]$\Rightarrow \ln \frac{K_1}{K_2}= - \frac{E_a}{R} \left(\frac{1}{T_1} -\frac{1}{T_2} \right)$[/tex]

[tex]$\Rightarrow \ln \frac{K_2}{K_1}= \frac{E_a}{R} \left(\frac{1}{T_1} -\frac{1}{T_2} \right)$[/tex]

Given, [tex]$E_a = 0.269$[/tex] J/mol

           R = 8.314 J/mol/K

[tex]$\Rightarrow \ln \frac{K_2}{K_1}= \frac{0.269}{8.314} \left(\frac{1}{300} -\frac{1}{310} \right)$[/tex]

[tex]$\Rightarrow \ln \frac{K_2}{K_1}= \frac{0.269}{8.314} \times \frac{10}{300 \times 310}$[/tex]

[tex]$\Rightarrow \ln \frac{K_2}{K_1}= 3.479 \times 10^{-6}$[/tex]

[tex]$\Rightarrow \frac{K_2}{K_1}= e^{3.479 \times 10^{-6}}$[/tex]

[tex]$\Rightarrow \frac{K_2}{K_1}= 1$[/tex]

∴ [tex]$K_2=K_1$[/tex]

So, no this reaction does not seem to follow the thumb rule as its activation energy is very low.

Answer:

Calculate moles KCl: 2.55 g / 74.55 g/mol = 0.0342 moles KCl

Volume KCl = 0.0342 mol X (1 L/0.150 mol) = 0.228 L X 1000 mL/L = 228 mL

Explanation:

Volume=288mL

Given:

Molarity=0.140 M

Mass=2.65 g

To find:

Volume=?

Molar mass of KCl = 74.55 g/mol

Firstly, we need to calculate the number of moles of KCl:

[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}} \\\\\text{Number of moles}=\frac{2.65g}{74.55g/mol} \\\\\text{Number of moles}=0.0355 moles[/tex]

In order to calculate the volume,

[tex]\text{ Volume of KCl} = 0.0342 mol * (1 L/0.150 mol) \\\\\text{ Volume of KCl} = 0.228 L * 1000 mL/L \\\\\text{ Volume of KCl} = 228 mL[/tex]

The volume in mL will be 228mL.
