Why is the delivery tube removed from the water as soon as heating is stopped in cracking?
The delivery tube is removed from the water as soon as heating is stopped in cracking to prevent backflow of water into the apparatus. If the tube remains submerged while cooling, a vacuum can form that might draw water back, potentially contaminating the products or damaging the equipment. Additionally, removing the tube helps to safely release any built-up pressure and allows for proper handling of the reaction products.

Why should distillation be stopped before the flask reaches dryness?
Distillation should be stopped before the flask reaches dryness to prevent the heating element from coming into contact with the dry residue, which can lead to overheating, thermal decomposition, or the risk of fire. Additionally, stopping before dryness helps avoid contamination of the distillate with impurities from the residue.

Why did American eventually stop using kerosene?
Americans eventually stopped using kerosene primarily due to the rise of electricity as a more convenient and efficient energy source for lighting and heating. The development of electric lighting technology made it safer and easier to illuminate homes and businesses without the risks associated with kerosene lamps. Additionally, the widespread availability of natural gas further contributed to the decline of kerosene usage for heating and cooking. As infrastructure for electricity and gas improved, kerosene became largely obsolete in many households.

Why should the delivery tube be removed from the water before the heating is stopped in cracking?
Removing the delivery tube from the water before stopping the heating in cracking prevents water from being sucked back into the reaction flask due to a sudden decrease in pressure. This could cause the flask to crack or shatter, posing a safety risk.
