<u>Answer:</u> The solubility of oxygen at 682 torr 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 oxygen gas
are the final concentration and partial pressure of oxygen gas
We are given:
Conversion factor used: 1 atm = 760 torr
Putting values in above equation, we get:
Hence, the solubility of oxygen gas at 628 torr is
Answer:
High surface tension causes boiling point to increase.
Explanation:
The surface tension is related to the psychical forces between the molecules. Increasing the surface tension will increase the amount of energy (heat) needed to take the molecules apart and go from liquid state to vapor state, so the boiling point of the particular liquid will increase.
Answer:
Explanation:
Hello!
In this case, according to the Charles' law as a directly proportional relationship between volume and temperature:
Thus, in order to compute the final volume, V2, we obtain the following expression:
Best regards!
At first I thought it was c but then I checked And it’s either B or A? I’m thinking mostly A but good luck
Answer:2
Explanation:because the compound is CaI2, Ca needs to lose 2 electrons and I needs to gain 1 electron to reach an octet and so there will be 2 I atoms therefore 2 electron transfer
