Answer:
C. as electrons jump from higher energy levels to lower levels
Explanation:
Atoms of elements are capable of emitting photons i.e. light energy. They, however, only do so when they become excited at first. They remain excited for a short while and then begin to move from their excited electron level to a lower level.
As they move from high electron level to low electron level, atoms emit light energy in form of visible, ultraviolet light in a process called SPONTANEOUS EMISSION. Therefore, according to this question, atoms emit visible and ultraviolet light as electrons jump from higher energy levels to lower levels.
<span>I believe the correct 2nd reaction is:</span>
cof2(g)⇌1/2 co2(g)+1/2 cf4(g)
where we can see that it is exactly one-half of the
original
Therefore the new Kp is:
new Kp = (old Kp)^(1/2)
new Kp = (2.2 x 10^6)^(1/2)
<span>new Kp = 1,483.24 </span>
Part 1 : Answer is only B substance is soluble in water.
In this experiment undissolved mass of each substance was measured. According to the given data, undissolved mass of substance B at 20 °C is 10 g while A is 50 g. Since, the initial added mass of each substance is 50 g, we can see that substance A is not soluble in water since the undissolved mass is 50 g.
Part 2 : Substance A is not soluble in water and substance B is soluble in water.
According to the given data, the undissolved mass of substance A remains as same as initial added mass, 50 g throughout the temperature range from 20 ° to 80 °C. Hence, we can conclude that substance A is not soluble in water.
But, according to the data, undissolved mass of substance B at 20 °C is 10 g. That means, 40 g of substance B was dissolved in water. When the temperature increases the undissolved mass of substance B decreases. Hence, we can conclude that substance B is soluble in water and solubility increases with temperature.
i think the greater the electric charge the atom decreases in size
