Why receiving flask supposed to be kept on ice during preparation of cyclohexene?
Keeping the receiving flask on ice helps to condense the volatile cyclohexene vapors back into liquid form, making it easier to collect the product. This method ensures a higher yield of cyclohexene by preventing the loss of product due to vaporization.
What is Aragonite to Calcite?
•Aragonite is a metastable calcium carbonate • •Calcium carbonate is stable • •Will recrystallize to calcite during diagenesis
How many isomers does the dehydration of cyclohexanol have?
The dehydration of cyclohexanol can form two isomers: cyclohexene and cyclohexadiene. These isomers result from different locations of the double bond formed during the dehydration process.
In terms of particles how and why the rate of reaction changes during the reaction of calcium carbonate with hydrochloric acid.?
The chemical reaction goes faster if calcium carbonate is powdered.
What is a common carbonate mineral that replaces a mineral in fossils?
Calcite is a common carbonate mineral that often replaces the original mineral in fossils during the fossilization process. Calcite can help preserve the structure of the fossil while replacing the original material.

Why sodium carbonate is used in preparation of thiosulphate solution?
Sodium carbonate is used in the preparation of thiosulfate solution to help maintain a stable pH level during the reaction. It acts as a buffer to prevent large fluctuations in pH that could affect the reaction rate or yield of the thiosulfate solution. Additionally, sodium carbonate helps to dissolve the thiosulfate salt more effectively in water during the preparation process.
Why you add sodium carbonate to the mixture during preparation of ester?
Sodium carbonate is added during the preparation of esters to neutralize the acidic byproduct formed during the reaction. This helps to facilitate the esterification reaction and improve the yield of the desired ester product.
Why it is necessary to add sodium carbonate during the preparation of sodium fusion tube?
Sodium carbonate is added during the preparation of a sodium fusion tube to help create a more basic environment that promotes the formation of water-soluble compounds. This facilitates the extraction of certain metals or elements present in a sample through the formation of stable and soluble complexes. Additionally, sodium carbonate helps prevent the formation of unwanted side products during the fusion process.
Why the brown color of bromine disappear when mixed with cyclohexene?
Halogens react with alkenes to form haloalkanes. Addition of the bromine in this case occurs across the double bond in cyclohexene. The resultant products are colourless hence the brown colour disappears.
How cyclohexene might be formed as a byproduct in the synthesis of cyclohexanone?
Cyclohexene can be formed as a byproduct in the synthesis of cyclohexanone through dehydration of cyclohexanol. During the oxidation of cyclohexanol to cyclohexanone, some cyclohexanol may lose a water molecule, undergo dehydration, and form cyclohexene as a byproduct. This side reaction can occur when the temperature and reaction conditions favor dehydration over oxidation.
What was the salt like chemical that was used to embalm the organs?
Natron, the name of a naturally occurring sodium carbonate compound, was used in the embalming process during the preparation of mummies. Deposits of this mineral were mined from dry lake bottoms in Egypt.
What is Aragonite to Calcite?
•Aragonite is a metastable calcium carbonate • •Calcium carbonate is stable • •Will recrystallize to calcite during diagenesis

What is safe to take for a cold while pregnant?
Paracetamol, chlorpheniramine with phenylephrine preparation is considered as safe preparation, during pregnancy.
