Answer : The correct option is, (3) titration
Explanation :
Titration : It is a laboratory process where we have to use the volume of a solution of known concentration to determine the concentration of unknown solution.
Distillation : It is a process in which we used to separate a pure liquid from the mixture of the liquids based on the different boiling points.
Fermentation : It is a chemical process in which the the bacteria, an organism or yeast converts the carbohydrate into an alcohol or an acid.
Transmutation : It is a process in which the nucleus of a chemical elements changes into another.
Hence, the correct option is, (3) titration
Answer:
it would be ionic
copper forms a cation and oxygen forms an anion
those charges represent the e-s that are transferred during bonding
oxygen is -2 so will accept 2 e-s to achieve noble gas configuration
Explanation:
Answer:
counter clockwise
Explanation:
Dont all planets in our solar system rotate counterclockwise?
Answer:
Chlorination of a 1° alcohol using Thionyl Chloride - an SN2 process
Alkene formation via POCl3 reaction with a 2º alcohol - an El process
Explanation:
For a primary alcohol, the chlorination occurs by SN2 mechanism. Remember that the order of SN2 mechanism is methyl > primary > secondary > tertiary. This means that a primary alkyl halide will undergo nucleophillic substitution by SN2 mechanism.
For a secondary alkyl halide, we normally expect that the mechanism will be E2. When we use POCl3 and pyridine, the alkyl halide passes through a carbocation intermediate which is characteristic of an E1 mechanism.
