Typically, the actual yield is lower than the theoretical yield because few reactions complete (i.e., are not 100% efficient) or because not all of the product in a reaction is collected. It is also conceivable for the real yield to exceed the theoretical yield.
What is theoretical yield ?
Theoretical yield is what would be obtained if 100% of the reaction was completed and no product was wasted in any way; however, procedures are not this efficient. Everything is dependent on the experimenter's precision and the reaction. Some reactions are reversible, meaning that less than 100% of the reaction proceeds to completion; some reactions do not go to completion because they require a large amount of energy or additional time, for example. Substances in the reaction may be lost throughout the method or difficult to separate from other sections of the experiment. In chemistry, some degree of inaccuracy is always expected.

Ethylene is a hydrocarbon which has the formula C ₂H ₄ or H₂C=CH₂. It is a colourless flammable gas with a faint "sweet and musky" odour when pure. It is the simplest alkene.
Ethylene is widely used in the chemical industry, and its worldwide production exceeds that of any other organic compound.
<h3>What is ethylene used for?</h3>
Medical: Ethylene is used as an anaesthetic. Metal Fabrication: Ethylene is used as oxy-fuel gas in metal cutting, welding and high velocity thermal spraying. Refining: Ethylene is used as refrigerant, especially in LNG liquefaction plants. Rubber & Plastics: Ethylene is used in the extraction of rubber.
<h3>Is ethylene harmful to humans?</h3>
* Ethylene gas can affect you when breathed in. * Skin contact with liquid Ethylene can cause frostbite. * Exposure to Ethylene can cause headache, dizziness, fatigue, lightheadedness, confusion and unconsciousness. * Ethylene is a HIGHLY FLAMMABLE and REACTIVE chemical and a DANGEROUS FIRE and EXPLOSION HAZARD.

C – coming to
senses and finally realized that everything is dynamic and I should learn to

someday, these changes will actually make sense and that all of these questions

whatever happens, I must learn to

the different things I see everyday, If the world changes for its betterment or
for its worse, then I too, should change as well to go with the flow. However,
keep in mind to

the small things behind because these things when summed up actually what make
sense of everything and could possibly answer the
