What gas do human and animals breathe out?
We breath in air (left), breath out (right) which is approx;Nitrogen 79% -----------------------Nitrogen 79%Oxygen 20% -------------------------Oxygen 16%Argon 1%--------------------------------- Argon 1%Carbon dioxide 0.0384% ---carbon dioxide 4%We breath out air with a higher level of carbon dioxide and a lower level of oxygen; breathing also results in loss of water from the body, exhaled air has a relative humidity of 100% (with trace's of methanol and other organic compounds generated inside the body).humans breathe in oxygen and breathe out carbon dioxideCabon dioxide
Glycerin is it made from pig?
To summarize the process, not directly. Glycerin is a colorless, odorless, viscous liquid that is widely used in pharmaceutical formulations. Since glycerol forms the backbone of triglycerides, it is produced by saponification or transesterification. These processes are seen in soap-making and biodiesel production. Glycerol is a 10% by-product of biodiesel production. The process involves reacting vegetable oils or animal fats catalytically with a short-chain aliphatic alcohols (typically methanol or ethanol) to produce the fuel and glycerol. Hence glycerol is created by processing a variety of fats from both animals and vegetables and not from pigs alone.
Is methanol good solvent for extraction?
No, due to two reasons 1- edible oils are not soluble in methanol,2- methanol is a poisoness liquid.
Why are methanol and ethanol not used for extractions?
They are used in liquid:liquid extractions, methanol especially. What extraction are you performing? plant extraction for antimicrobial activities and phytochemical ivestigation
What is the role of methanol in the extraction of chlorophyll?
serves as catalyst
How do you separate methanol from surfactants?
There are a number of methods that can be used to separate methanol from surfactants. The most effective method is extraction of the cationic surfactants by contracting the mixture with water.
Why is the enthalpy change of combustion for methanol less negative than methane?
The combustion of methanol to form products of H2O and CO2 do not have as much of an energy change compared to methane and a result methanol releases less energy compared to methane. The more negative an enthalpy change is, the more heat it is going to release.
If you fixed a tissue in ethanol that have methanol or other toxic material and then you extract DNA from it does the DNA functionable for PCR?
It depends on the method of extraction. Extraction that involve the use of resins of ionic exchange or affinity should be able to eliminate other substances.
What is successive extraction?
Successive extraction of any plant part involves sequential extraction ( e.g. employing soxhlet apparatus or maceration) using solvents with increasing polarity. Following each extraction, the marc (refuse matter that remains after extract has been filtered) will be dried before being extracted using solvent with higher polarity. For example, the following solvents can be used in successive order (lower to higher polarity): petroleum ether then chloroform then ethyl acetate, then methanol.
What is methanol's shape?
methanol is liquid
What compounds are found in methanol?
Methanol is an alcohol and consists of carbon,hydrogen and oxygen its formula is CH3OH
Why is heat generated when water is added to methanol?
It is because of the difference between the way molecules are hydrogen bonded to each other in the mixture compared to the pure liquids.
Why is methanol more polar than ethanol?
Methane is CH4 or H-CH3 Ethane is CH3-CH3 When compared to H- (in methane), the CH3- (methyl group in ethane) is more electron donating and hence ethane is more basic than methane.
Is methanol a solid?
No, at room temperature methanol is a liquid.
