<u>Answer:</u> The Henry's law constant for oxygen gas in water is 
<u>Explanation:</u>
To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,
= Henry's constant = ?
= solubility of oxygen gas = 
= partial pressure of oxygen gas = 2.1 atm
Putting values in above equation, we get:

Hence, the Henry's law constant for oxygen gas in water is 
Answer:
Particles in a solid object are super tight and close to eachother. They do not move past eachother because it is a solid, not a liquid or gas.
Explanation:
Answer:
1) Increasing temperature
2) Stirring
3) Increasing surface area of salt by grinding it
Answer:
Plants consume carbon through transpiration
Explanation:
In transpiration, plants lose water vapor through the stomata in their leaves. No carbon is involved in transpiration, which has an outbound direction. Nothing can be consumed through the stomata when vapor is going out of the plant. It´s like trying to get in through the exit.
I think the anwer is electrolyte :)... i had it on a test a couple days ago.
