Answer: The statement, average kinetic energy of the gas particles is greater in container A because its particles move faster is correct.
Explanation:
Kinetic energy is the energy obtained due to the motion of an object or substance.
where,
T = temperature
This means that kinetic energy is directly proportional to temperature.
So, when heat is provided to container A then its molecules will start to move rapidly from one place to another which will cause more collisions between the atoms.
Hence, average kinetic energy will be more in container A.
Whereas container B is placed at room temperature which is low than that in container A. So, molecules in container B will move at almost same speed and therefore, specific collisions will be there. So, average kinetic energy in container B will be less than that in container A.
Thus, we can conclude that the statement, average kinetic energy of the gas particles is greater in container A because its particles move faster is correct.
Answer:
37 mmol of acetate need to add to this solution.
Explanation:
Acetic acid is an weak acid. According to Henderson-Hasselbalch equation for a buffer consist of weak acid (acetic acid) and its conjugate base (acetate)-
Here pH is 5.31, (acetic acid) is 4.74 and number of mmol of acetic acid is 10 mmol.
Plug in all the values in the above equation:
or, mmol of = 37
So 37 mmol of acetate need to add to this solution.
Answer:
Follows are the solution to this question:
Explanation:
Please find the image file of the chemical reaction in the attachment:
In a water medium, the CH3- type CH 3Li is a heavy nucleophile that attacks the carbonyl carbon atom to form the alkoxide ion, which will then be protonated to form alcohol.
