Answer:
Solvent will be lost as gas and not return into the vessel via condensation.
Explanation:
Reflux is a technique used in chemistry to boil a particular solvent and convert the gas formed back into liquid by condensation. This technique allows a solvent to be heated at a regulated temperature but for a prolonged period of time than it would normally take place.
The reflux procedure makes use of a reflux CONDENSER, which is an apparatus that allows vapour from the heating/boiling to flow back into the reaction vessel. The CONDENSER functions to prevent the loss of the SOLVENT as vapour by providing a cooling effect on the vapour.
Therefore, if a reaction was refluxed without a condenser, THE SOLVENT WILL BE LOST AS VAPOUR
A. 5 It can either 3 or 5 you search it up in google
The correct reference for this isotope is A. Oxygen-18.
Answer:
Explanation:
Hello,
In this case, given the temperature, volume and total pressure, we can compute the total moles by using the ideal gas equation:
Next, using the molar fraction of argon, we compute the moles of argon:
And the moles of methane:
Now, by using the molar masses of both argon and methane, we can compute the mass percent of argon:
