Answer:
The value of Ka
It is a weak acid
Explanation:
From the question we are told that
The concentration of
The concentration of
The concentration of
Generally the equation for the ionic dissociation of is
The equilibrium constant is mathematically represented as
Substituting values since all value of concentration are at equilibrium
Since the value of is less than 1 it show that in water it dose not completely
disassociated so it an acid that is weak
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.
