What is the catalyst used for hydrogenation of oils?
Due to fast reaction and increase D20 value or Hardness and low quantity of Hydrogen gas used catalysts are required for the reaction to be usable , as non catalytic hydrogenation takes place only at very high temperatures
Oxidation reaction vs reduction reaction?
As far as I can gather from mark schemes of A level papers... Hydrogenation is simply ADDING HYDROGEN, whereas reduction is removing O2 for example and replacing it with H2 Example: In this test paper, the marks are given for Hydrogenation ONLY, not reduction: H2C=CH2 + H2 --> CH3CH3 In this test paper, the marks are given for reduction ONLY, and not hydrogenation: C6H5NO2 + 3H2 --> C6H5NH2 + 2H2O (NitroBenzene) (AminoBenzene/phenylamine) This is just interpretation of the mark scheme, not concrete proof.
What requires the use of an autoclave?
I think ther is only one way to use any particular autoclave product. However, if you are inquiring about things which can be sterilized in an autoclave--: Dental instruments, medical instruments, barber and beautician implements, veterinary implements, eating utensils are all some. To sterilize medical instruments
What type of reaction is exhibited by alkenes?
Alkynes undergo many addition reactions such as: catalytic hydrogenation, addition by electrophilic reagents, hydration with tautomerism, hydroboration reactions, and oxidations. They also undergo nucleophilic addition reactions & reduction. Finally alkynes are the strongest bronsted acids made from only hydrocarbons.
Compounds can be separated into their constituent elements only by what reaction?
Compounds can be separated into their constituent elements only by a decomposition reaction.

What is the basics of hydrogenation of fats?
Hydrogenation - to treat with hydrogen - is a chemical reaction between molecular hydrogen (H2) and another compound or element, usually in the presence of a catalyst. The process is commonly employed to reduce or saturate organic compounds. Hydrogenation typically constitutes the addition of pairs of hydrogen atoms to a molecule, generally an alkene. Catalysts are required for the reaction to be usable; non-catalytic hydrogenation takes place only at very high temperatures. Hydrogen adds to double and triple bonds in hydrocarbons.Because of the importance of hydrogen, many related reactions have been developed for its use. Most hydrogenations use gaseous hydrogen (H2), but some involve the alternative sources of hydrogen, not H2: these processes are called transfer hydrogenations. The reverse reaction, removal of hydrogen from a molecule, is called dehydrogenation. A reaction where bonds are broken while hydrogen is added is called hydrogenolysis, a reaction that may occur to carbon-carbon and carbon-heteroatom (oxygen, nitrogen or halogen) bonds. Hydrogenation differs from protonation or hydride addition: in hydrogenation, the products have the same charge as the reactants.An illustrative example of a hydrogenation reaction is the addition of hydrogen to maleic acid to form succinic acid. Numerous important applications of this petrochemical are found in pharmaceutical and food industries. Hydrogenation of unsaturated fats produces saturated fats and, in some cases, trans fats.

How do you sterilize a belly bar?
Unless you have access to an autoclave (which you quite possibly don't) your only option is to take it to your local body piercing studio and have them autoclave the jewellery piece for you (they will charge you for this service). Only an autoclave can properly sterilize jewellery to ensure that bacterial growth and spores are killed.
An autoclave is used to sterilize surgical equipment because?
Because non-sterile surgical equipment can carry infectious diseases, bacteria and other organisms from patient to patient which can only be eliminated by an autoclave.
How can I sterilize needles used in tattooing?
You really should not be reusing needles to tattoo someone. If you are going to though, the only way to properly sterilize them is by using an autoclave. An autoclave uses extreme pressure and heat to kill germs and bacteria.
What is the chemical reaction between sodium acetate and sodium hydroxide?
There is no reaction between them: They only 'could exchange' the H+ and Na+ ions but the products are identical to the reactants.CH3COOH + CH3COONa --> CH3COONa + CH3COOH
What will you do when people ccall you big nose?
Ignore it. This is really mean but they are only doing it so they get a reaction from you. If it continues or gets worse, tell an adult. They can help.
What type of reaction adds oxygen to an element?
When oxygen is added to an element through a chemical reaction, this is called oxidation. A common oxidation is the formation of rust.

How does combustion differentiate between saturated and unsaturated hydrocarbons?
The primary difference is that an unsaturated hydrocarbon contains a C=C double bond allowing it to undergo addition reactions. Saturated hydrocarbons contain only C-C single bonds so only substitution and elimination can occur. The difference can be seen experimentally as an unsaturated hydrocarbon (eg ethene) will decolourise bromine water.
