When the 0.10 m solution of hclo2 is allowed to come to equilibrium, what percent of the acid molecules are ionized?
docker41 [41]

If 0.10 m solution of hclo2 is allowed to come to equilibrium, the percent of the acid molecules that is ionized is 29%

We have

HClO2 = 0.1 mole = 0.012

HClO + H2O ⇄ ClO₂⁻ + H₂O

Ka = 0.1α x 0.1α / 0.1(1-α)

= 0.1α²/1-α = 0.12

We have to form a quadratic equation from the above

0.1α² = 0.012 - 0.12α

We write the equation to be

0.1α² + 0.012 - 0.12α = 0

To solve the equation above, the quadratic formula calculator was used.

\frac{-b+-\sqrt{b^2-4ac} }{2}

alpha = 0.29

This is 29 percent. Therefore the percentage of ionization is 29%.

<h3>What is ionization?</h3>

This is the process through which neutral ions are chraged to become electrically charged.

Which complex number is represented by the point graphed on the complex plane below? –4 + 3i 3 + 4i 3 – 4i 4 + 3i.
nata0808 [166]

The complex number represented by the point graphed on the complex plane below is -3-3i

Complex number is generally expressed as z = x + iy

where:

  • x is the real axis
  • y is the imaginary axis

From the complex plane shown, we can see that the point lies in the Quadrant III of the xy plane.

The coordinate of the point on the plane is given as (-3, -3). This can be represented in complex notation as -3 - 3i

Find the 45th percentile of the data set. Give your answer to three decimal places.
Schach [20]

The 45th percentile of the data given above (P₄₅) is 16.225.

<h3>What is percentile in statistics?</h3>

Percentile refers to the mathematical or statistical term that is used to indicate the position of a data in relation to others from the sample given.

<h3>How did we arrive at the above figure?</h3>

Step 1 - First all data must be arranged in ascending order:

See the attached table for this.

Step 2 - We compute the position or rank of the 45th percentile.

The formula for percentile position is given as:

((n +1 ) *P)/100

= ((25+1) * 45)/100

= 11.70

Step 3 - Deploy the interpolation method because the position above is not an integer.

The numbers in positions 11 and 12 are where you'll find the 45 percent percentile. Based on the data arranged in ascending order, the values are 15 and 16.75.

The percentile we're seeking for is situated at the value of 11.7 - 11 = 0.7, which is the percentage of the space between 15 and 16.75.

Therefore,

(P₄₅) = 15 + 0.7 x (16.75 - 15)

(P₄₅) =16.225.
