Explanation:
21. The given molecule for cracking is tetradecane.
On cracking it forms one mole of decane (C10H22) and two moles of ethene gas.
The chemical equation is shown below:
22. The essential condition for the formation of an ester is the reaction of alcohol and acid in presence of concentrated sulfuric acid.
Thus among the given options, the first option is the correct one.
23. Isomers of butanol are shown below:
It is 2-butanol.
The position of -OH group changes to the second carbon.
Answer : The partial pressure of nitrogen gas in the mixture is, 9.88 atm
Explanation :
According to the Dalton's Law, the total pressure of the gas is equal to the sum of the partial pressure of individual gases.
Formula used :
where,
= total pressure of gas = 13.6 atm
= partial pressure of helium gas = 1831 torr = 2.41 atm
= partial pressure of argon gas = 997 torr = 1.31 atm
Conversion used: (1 atm = 760 torr)
= partial pressure of nitrogen gas = ?
Now put all the given values in the above formula, we get:
Thus, the partial pressure of nitrogen gas in the mixture is, 9.88 atm
