The point of distillation (of alcohol) is to separate the ethanol from the other undesired components. The distillation process takes advantage of the different volatilities. In the fermented MASH are undesired substances more volatile than ethanol (e.g. methanol) which will distill out first. This is the Heads and is discarded. Once these more volatile compounds are eliminated you have the Heart of the run which is the quality product. Finally if you keep distilling you begin getting some undesirable lower volatility substances, oils and water, the Tails, which is also discarded by stopping the distillation run. The art of the experienced distiller is to know when to draw the lines between Head, Heart, and Tail. The more selective one is, the higher quality (but less quantity) of the produced distillate.

If the distillation flask is not securely attached to the distillation head, there is a risk of the flask falling off during the distillation process, which can cause spillage of the liquid being distilled and potentially lead to equipment damage or personal injury. It is essential to ensure a proper connection to maintain a safe and efficient distillation process.
A steam distillation sloping splash head is a glassware attachment used in steam distillation setups. It is placed on top of the distillation flask to prevent carry-over of boiling liquid into the condenser. As the vapor rises, it hits the sloping surface, condenses, and falls back into the flask, ensuring that only vaporized compounds are carried into the condenser for distillation.

The head-to-tail rule is a method used in vector addition where vectors are added tip-to-tail. This involves placing the tail of one vector to the head of the other vector in order to determine the resultant vector. The resultant vector is then the vector that connects the tail of the first vector to the head of the last vector in the series.
No, it is located in their thorax just below the head. But it does seem that way because their exoskeleton covers its short thorax so it looks like it only has two parts, the head and the tail.

A shrimps heart is located on its head. If we base it on the exact anatomy of a shrimp, its heart is located on its thorax just after the head, but both the head and the thorax are covered with a single exoskeleton only, that is why the shrimps thorax can be mistaken as still part of the shrimps head. But in general, we see a shrimp divided only into 2 parts, the head and the tail, we see no thorax in it.
