A group of Chemistry students have 1.0 mole each of two mystery substances, Substance X and Substance Y, at 50° C. Explain why a conclusion about the kinetic energy of each substance is not possible. (Write in short answer form--- 3-5 sentences)

The temperature of a substance in chemistry, is taken as a measure or estimate of the average kinetic energy () of the atoms or molecules contained in the substance. The 6.02 × 10²³ particles (atoms or molecules) within 1.0 mole of each substance can each posses different amount of kinetic energy at any given time. Some particles move very fast while others move very slow such that the kinetic energy of all the particles are only representable by a distribution and a conclusion regarding the  different aspects of the kinetic energy distribution of the particles of the substances is not easily possible

Explanation:

For a gas, we have;

Where;

= The average kinetic energy

k = 1.38 × 10⁻²³ J/K

T = The gas temperature in Kelvin

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
