Vacuum filtration is a process of separating the solid from liquids. A Buchner funnel and side arm flask is used for this process. The filter paper is placed on the Buchner funnel, the size of the filter paper should fit on the funnel and should cover all the holes. To obtain the correct yield of the solid product from the vacuum filtration process, there should be no gaps around the edges of the filter paper as if there are any gaps around the edges of the filter paper, the solid precipitate will pass through the gaps with liquid and thus, results in the low percentage yield of the solid compound.
Hence, to obtain the correct yield percentage of the solid compound there should be no gaps around the edges of the filter paper during the vacuum filtration.
Answer:
Ozone (O3) is composed of the ozone gas (90% of the total ozone in the atmosphere). The ozone has three oxygen atoms, and it is the result of the action of Ultra Violet (UV) radiation on oxygen molecules, composed of two oxygen atoms.
Explanation:
ozone is harmful for living things. But if it's still far away up, it won't contaminate the air.
When solid aluminum metal is reacted with diatomic chlorine gas, solid aluminum chloride is formed. This reaction is an example of synthesis or chemical combination in which two elements, aluminum and chlorine combine to form a new compound aluminum chloride.
Word equation: Aluminum (s)+ Chlorine (g)---> Aluminum chloride(s)
Molecular formula of the product formed is .
Therefore the balanced chemical equation representing the reaction of solid aluminum with gaseous dichlorine can be represented as,
