A, the higher the temperature, the faster the average kinetic energy
<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)
<u>Answer:</u> The solubility of nitrogen gas at 5.00 atm is
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:
Or,
where,
are the initial concentration and partial pressure of nitrogen gas
are the final concentration and partial pressure of nitrogen gas
We are given:
Putting values in above equation, we get:
Hence, the solubility of nitrogen gas at 5.00 atm is
Answer:
Characteristics: Oxygen in its common form (O2) is a colorless, odorless and tasteless diatomic gas. Oxygen is extremely reactive and forms oxides with nearly all other elements except noble gases. Oxygen dissolves more readily in cold water than warm water.
