What is the name of this alkane?
2 answers:
Answer:
Name of this alkane is 1-ethyl-3-methylcyclohexane
Explanation:
It is a derivative of cyclohexane. So main carbon chain is cyclohexane.
There are two substituents- methyl and ethyl
Numbering starts by assigning carbon attached with ethyl group as 1 and carbon attached to methyl group is numbered as 3 to give lowest possible numbering.
Carbon bearing ethyl group is numbered as 1 because "e" comes first compared to "m" in alphabetical order

Answer: 1.87 atm
Explanation:
Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.
The combined gas equation is,
where,
= initial pressure of gas = 2.50 atm
= final pressure of gas = ?
= initial volume of gas = 26.4 ml
= final volume of gas = 36.2 ml
= initial temperature of gas =
= final temperature of gas =
Now put all the given values in the above equation, we get:
The new pressure is 1.87 atm by using combined gas law.
