<h3>Answer:</h3>
C. 9
<h3>Explanation:</h3>
There are 2 electrons in the first shell, and 7 in the second, for a total of 9.
A flouride ion, on other hand, would have 8, since it fills that second shell with an extra electron (that's why it has a charge of -1)
Answer : The amount of heat released, -35057 J
Solution :
Process involved in the calculation of heat released :
Now we have to calculate the amount of heat released.
where,
Q = amount of heat released = ?
m = mass of water = 18 g
= specific heat of liquid water =
= enthalpy change for condensation = -40700 J/mole
Now put all the given values in the above expression, we get
Therefore, the amount of heat released, -35057 J
I believe it would be a compound.
A cloud is formed because the water vapor gathers in groups
