Answer:
Explanation:
From the information given, we are to show the product of the reaction between the alcohol (stick formula) with pyridinium chlorochromate. The reaction starts with the nucleophilic addition of Cr with oxygen molecule on the alcohol. Then, deprotonation of oxygen occurs, this process is followed by the removal of hydrogen ion to yield the final product. The reaction mechanism can be seen from the attached image below.
Answer:
691.29 K or 418.14 °C
Explanation:
Hello, at first the moles of oxygen gas are required:
Now, based on the ideal gas equation, we solve for the temperature:
Best regards.
Answer: Option (c) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
Since, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then this will also lead to increase in kinetic energy of the molecules of a substance.
So, when a solid substance is dissolved in a solution whose temperature is increased then molecules of the solid will also gain kinetic energy. As a result, more number of collisions will occur due to which bond between the molecules of solid will break.
Therefore, there will be increase in solubility of the solid.
Thus, we can conclude that an increase in the temperature of a solution usually increases the solubility of a solid solute in the solution.
