The answer to the first part of question is: During condensation in reflux condenser, the maximum height is halfway up to the condenser.
And the answer to second question is this that if solvent condenses higher than this maximum height, all of the solvent may run back into the reaction flask or may be the reaction will start earlier. if the solvent do not go up than the maximum height, the reaction does not happen to start earlier.
I’m not sure but i think blue
It’s definitely B but I’m not sure
Argon is the third most common gas found in the air we breathe. The air we breathe has approximately 78% nitrogen and 21 % oxygen. The third more abundant gas in the air we breathe is Argon. It is available in a very small quantity in the air that we breathe.
The percentage of the gas argon is about 0.9% in the air
that we breathe. There are several other gases also present in the air that we
breathe, but they are found mostly in negligible amounts.
