In Fisher esterification, sulfuric acid is used as a catalyst and its function is to convert the carboxylic compound in its conjugate acid. This favours the nucleophilic attack of the alcohol. To act as a catalyst you need a strong acid, therefore sulphuric acid is suitable for this kind of reaction.
Answer:
The number of moles of nitrogen in the tank are 1,98.
Explanation:
We apply the ideal gas law, convert the temperature unit in Celsius to degrees Kelvin, solve for n (number of moles). The gas constant R is used with a value of 0.082 l atm / K mol:
0°C= 273 K ---> 19, 71°C= 273 + 19,71= 292, 71K
PV= nRT ---> n=PV/RT
n= 4,97 atm x 9,583 L/ 0.082 l atm / K mol x 292, 71K=<em> 1, 98 mol</em>

Answer:
Upward delivery or downward displacement of air
Explanation:
The method of collection of a gas is dependent on it's density.
Gases that are less dense than air are collected by upward delivery or downward displacement of air while gases that are denser than air are collected by downward delivery or upward displacement of air.
Hydrogen is less dense than air hence it is collected by upward delivery or downward displacement of air.
