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.

4 features of bacteria that enable them to survive.
den301095 [7]

Answer:

Specific structural features that enable prokaryotes to thrive in diverse environments include their cell walls (which provide shape and protection), flagella (which function in directed movement), and ability to form capsules or endospores (both of which can protect against harsh conditions). Prokaryotes also possess biochemical adaptations for growth in varied conditions, such as those that enable them to tolerate extremely hot or salty environments.

Max (mass = 15 kg) is hanging from one end of a 13-m long bungee cord that has its other end fixed to a bridge above. The bungee
Rashid [163]

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals.

<h3>How to find the stress experimented by the bungee cord</h3>

Let suppose that the stress (\sigma), in pascals, experimented by the bungee cord is entirely <em>elastic </em>and <em>uniform</em>. By Newton's Laws we know that the tension (T), in newtons, experimented by the cord equals Max's weight. The stress on the bungee cord is axial and is described by following formula:

\sigma = \frac{m\cdot g}{\frac{\pi\cdot D^{2}}{4} }   (1)

Where:

  • m - Max's mass, in kilograms
  • g - Gravitational acceleration, in meters per square second
  • D - Diameter of the circular cross section, in meters

If we know that m = 15\,kg, g = 9.807\,\frac{m}{s^{2}} and D = 0.025\,m, then the stress experimented by the bungee cord is:

\sigma = \frac{(15\,kg)\cdot \left(9.807\,\frac{m}{s^{2}} \right)}{\frac{\pi}{4}\cdot (0.025\,m)^{2} }

\sigma \approx 299679.845\,Pa\, (299.680\,kPa)

The stress experimented by the bungee cord due to Max's weight is approximately 299.680 kilopascals. \blacksquare
