What is the molar concentration of potassium ions in a 0. 250 m k2so4(aq) solution?

Answers

The molar concentration of potassium ions in a  0. 250 m K₂SO₄(aq) solution is 2.

What is molar concentration?

The molar concentration of a solution is the presence of solute in one unit of a solution.

Molar concentration = number of moles / volume

The volume is given 0.250 m

To calculate the number of moles:

There will be 2 moles of potassium and  1 mole of sulfate in one L of the solution.

So in 0.250 L

0.250 x 2 x 1 = 0.500

The total number of moles of potassium and sulfate ion are 0.500

Now, putting the value:

Molar concentration = number of moles / volume

0.500 / 0.250 = 2

Thus, the molar concentration is 2.

Explanation:

If all other variables are held constant, you can find the pressure using Boyle's Law. The equation looks like this:

P₁V₁ = P₂V₂

In this equation, "P₁" and "V₁" represent the initial pressure and volume. "P₂" and "V₂" represent the final pressure and volume. You can plug the given values into the equation and simplify to find "P₂".

P₁ = 709 mmHg                      P₂ = ? mmHg

V₁ = 3.97 L                              V₂ = 5.36 L

P₁V₁ = P₂V₂                                                         <----- Boyle's Law

(709 mmHg)(3.97 L) = P₂(5.36 L)                      <----- Insert values

c) How many particles of sugar are there in the pop (3 marks)?

Answers

The number of sugar particles is 7.4 * 10^22 particles.

What is the mole?

The mole is used to describe the amount of substance. The idea was first introduced by Professor Avogadro and the number of particles that constitute one mole of a substance was said to be 6.02 * 10^23 particles in a mole.

Thus;

Molar mass of sugar = 342 g/mol

Number of moles of sugar = 42 grams/342 g/mol = 0.123 moles

Now;

If 1 mole of sugar costs 90 cents

0.123 moles of sugar costs 0.123 moles *  90 cents/1 mole

Answers

When comparing the titration curves for the titration of a strong acid with a strong base and the titration of a weak acid with a strong base, pH increases when we reach the equivalent point.

In strong acid and strong base

Initially the pH rises little by little. This is because the scale of the pH increases is logarithmic. Then it rises sharply near the equivalent point. At this point the remaining hydronium ions are low, and only a small amount of hydroxide ion is needed to raise the pH.

For weak acid and strong base

Answers

A student makes up 2 l of a 3. 0 m aqueous solution of HBr. to this solution she adds 1 l of a 4 m NaOH solution, then the pH of the resulting solution is 13.83.

What is normality?

Normality is defined as the ratio of equivalent mass of compound to the volume of solution in litre.

N1 is the normality of HBR = 3m

N2 is the normality of NaOH = 4m

V1 is the volume of the HBr = 2l

V2 is the volume of the NaOH = 1l

V is the total volume of solution = V1 + V2 = 2l +1l

= 3l

Normality of the solution = N

As we know that,

N1V1 - N2V2 = NV

3 × 2 – 4 × 1 = N × 3

6 – 4 = N – 3

N = 2/3 = 0.67 m

(OH-) = N = 0.67 m

Since normality of NaOH is greater than BR . Hence the resulting solution is alkaline.

pOH = -log[OH-]

POH = - log (0.67) = 0.17

As we know that,

A compound composed of 3. 3 % h, 19. 3 % c, and 77. 4 % o has a molar mass of approximately 60 g/mol. What is the molecular formula of the compound?.

Answers

The molecular formula of the given compound is [tex]$\mathrm{H}_{2} \mathrm{CO}_{3}$[/tex] also known as  Carbonic acid.

What is empirical formula and molecular formula?

The simplest whole-number ratio of the various atoms in a compound is represented by an empirical formula.

The precise number of various atom types present in a compound's molecule is indicated by the molecular formula.

Given that,

H = 3.3%

C = 19.3%

O = 77.4%

No. of moles of H = 3.3/1

No. of moles of H = 3.3

No. of moles of C = 19.3 / 12

No. of moles of C = 1.60

No. of moles of O = 77.4/16

No. of moles of O = 4.83

Therefore, the ratio of the atoms of C, H and O = 3.3 : 1.60 : 4.83

Divide by smallest value which you get =3.3 / 1.60 : 1.60 / 1.60 : 4.83 / 1.60

The ratio of the atoms of C, H and O = 2 : 1 : 3

So, the empirical formula is [tex]$\mathrm{H}_{2} \mathrm{CO}_{2}$[/tex]

Let the molecular formula is [tex]$\left(\mathrm{H}_{2} \mathrm{CO}_{3}\right) \mathrm{n}$[/tex]

Then, molar mass [tex]$=(2 \times 1+1 \times 12+3 \times 16) n\\[/tex]

Molar mass = 62n

As the question, 62 n = 60

n = 0.96 or n = 1 (rounded off to nearest ones)

So, the molecular formula is [tex]$\left(\mathrm{H}_{2} \mathrm{CO}_{3}\right) 1=\mathrm{H}_{2} \mathrm{CO}_{3}$[/tex] i.e., the compound is Carbonic acid.

Identify the location of reduction in an electrochemical cell. group of answer choices the electrode the anode the socket the cathode the salt bridge

Answers

The location of reduction in an electrochemical cell is called the anode.

An electrochemical cell ( galvanic cell ) is generate electric energy from chemical reactions. In galvanic cell species ( for example zinc and zinc cations ) from one half-cell lose electrons ( oxidation ) and species from other half-cell ( for example copper and copper cations ) gain electrons ( reduction ).  Electric current is generated due to the flow of electrons from the anode that undergoes an oxidation reaction to the cathode which has a reduction reaction in the circuit of an outer wire circuit.

If the viscosity of a solution is quadrupled, the rms-average distance of a collection of diffusing molecules from their starting point would be _________ over the same amount of time

Answers

The viscosity of a solution is quadrupled, the rms-average distance of a collection of diffusing molecules from their starting point would be [tex]\frac{1}{2}[/tex] over the same amount of time.

If the viscosity of a solution is quadrupled then the distance of collection of diffusing molecules would be half over the same amount of time. The viscosity of the molecules is dependent on density of the liquid. It is independent to the volume of the liquid.

What is viscosity?

Viscosity is measure of a fluid's resistance of flow.

The SI unit of viscosity is Poiseuille (PI) is other units ae newton second per square meter or pascal second. The dimensional formula of viscosity is [[tex]ML^{-1}T^{-1}[/tex]].

The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature.

η = [tex]\frac{2ga^{2} (Δρ)}{9v}[/tex]

Where (Δρ) is the density difference between fluid and sphere tested, a is the radius of the sphere, g is the acceleration due to gravity and v is the velocity of the sphere.

Viscosity Types:

Viscosity is the measure of fluid's friction to it's flow. There are two ways to measure the fluid is viscosity is follows:
