Potassium will loss it's electron because it have a character of electropositively therefore it's electron will transfer to flouren which will make stable and complete of it's electro configuration. Now potassium will have negative charge due to loss it's outer most electron on it's orbit and flourine will take negatively charge too because of complete it's outer most shell to be completed.(But we have to know that at first flourine was had a positive charge because of not completed of it's outer most shell)
Answer:
repeat the experiment
Explanation:
I am big brain. if she wants to know if it is correct, repeating the exact ay would show her if it is right or if she did something wrong
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.
Urea is highly soluble in water. When it is allowed to dissolve in water in the presence of heat, it will yield ammonia and carbon dioxide. The reaction is shown below:
<span>NH2-CO-NH2 + H2O </span>⇒ 2 NH3 + CO2
As you can observe in the stoichiometric equations, 1 molecule of water can dissolve with 1 mole of urea.
