When is the nax lunar eclipse?
The next total lunar eclipse will occur on December 21, 2010, and will be visible from anywhere in North America.
For detection of foregin element why is sodium fusion carried out?
oraganic compound are covalent in nature and they do not react with inorganic reagents so that they should be converted into ionic compounds .since sodium is highly reactive and electropositive metal ,it form ionic compound .NA+C+N...................NaCN(SODIUM CYNIDE)2Na+s......................Na2sNa+x.........................Nax
Illustrate with equation the preparation of alkanes by wurtz synthesis?
wurtz synthesis: 2CH3Cl + 2Na = CH3-CH3 + 2NaCl Grignard Synthesis: - Preparation of Grignard reagent: CH3Cl + Mg = CH3MgCl - Hydrolysis of Grignard reagent: CH3MgCl + HCl = CH3-H + MgCl2
How do eliminate biphenyl as a by product in a Grignard reaction?
Biphenyl will be dissolved in ether along with your desired product after Grignard synthesis. If you add an aqueous sodium hydroxide (NaOH) solution to this it will react with your desired product but not the biphenyl and form two layers of solution. One layer will be biphenyl dissovled in ether the other will be NaX (where X is your desired product, just with the Na attached to an oxygen rather than a H) dissolved in water. The latter solution can be separated with a separatory funnel; it will be the lower layer. To precipitate you product from its aqueous solution just cool it and add hydrochloric acid (HCl). There you have it, that's how to eliminate byphenyl from your desired product. Hope it helped.
Why do you prepare lassaigne extract?
lassaigne extractA small piece of sodium is heated gently in an ignition tube till the sodium melts. About 50 to 60 mg of the organic compound is added to this and the tube heated strongly for 2-3 minutes to fuse the material inside it. After cooling, the tube is carefully broken in a china dish containing about 20 to 30 mL of distilled water. The fused material along with the pieces of ignition tube is crushed with the help of a glass rod and the contents of the china dish are boiled for a few minutes. The sodium salts formed in the above reactions (i.e. NaCN, Na2S, NaX or NaSCN) dissolve. Excess of sodium reacts with water to give sodium hydroxide. This alkaline solution is called Lassaigne's extract or sodium extract. The solution is then filtered to remove the insoluble materials and the filtrate is used for making the tests for nitrogen, sulphur and halogens.ReactionsAn organic compound containing C, H, N, S and halogens when fused with sodium metal gives the following reactions.(NaSCN) is formed during fusion, which in the presence of excess sodium forms sodium cyanide and sodium sulphide.Detection of nitrogenA small quantity of the sodium extract is taken in a test tube. It is made alkaline by adding 2-3 drops of sodium hydroxide (NaOH) solution. 1 mL of freshly prepared solution of ferrous sulphate is added to this solution. The mixture of the two solutions is boiled and then acidified with dilute sulphuric acid. The appearance of prussian blue or green colouration of the precipitate confirms the presence of nitrogen in the given organic compound. The carbon and nitrogen present in the organic compound on fusion with sodium metal give sodium cyanide (NaCN) soluble in water. So, the sodium extract contains sodium cyanide which, on reaction with ferrous sulphate, gives sodium ferrocyanide. Some of the ferrous salt is oxidised to the ferric salt on heating and this reacts with sodium ferrocyanide to form ferric ferrocyanide.Note: When nitrogen and sulphur both are present in any organic compound, sodium thiocyanate is formed during fusion. When extracted with water sodium thiocyanate goes into the sodium extract and gives 'blood red coloration' with ferric ions due to the formation of ferric thiocyanate.Detection of sulphurThe presence of sulphur in any organic compound is detected by using sodium extract as follows:Lead acetate testA small portion of sodium extract is acidified with acetic acid and lead acetate solution is added to it. A black precipitate of lead sulphide indicates the presence of sulphur.Sodium nitroprusside testTo a small quantity of sodium extract taken in a test tube, 2 to 3 drops of sodium nitroprusside are added to the solution. A violet color indicates the presence of sulphur. This color fades away slowly on standing.by: zoren roicres apostol. copy and pastesource:http://www.tutorvista.com.

What are the release dates for Nic-Nax - 1926?
Nic-Nax - 1926 was released on: USA: 12 December 1926
How do you pronounce weichnachtsman the German word for santa?
Weihnachtsmann Vy (rhymes with try) - nax - mahn If you can make the "ch" sound correctly, then just say "nachts" instead of "nax"
What is the airport code for Kalaeloa Airport?
The airport code for Kalaeloa Airport is NAX.
How do you differentiate x2?
The derivative with respect to x of any term in this format: axn is equal to: nax(n -1) so in the case of x2, the answer will be: 2x(2 - 1) = 2x1 = 2x
What the derivetive of x2?
Any monomial in the format: axn has a derivative equal to: nax(n - 1) In this case, "a" is equal to 1 and "n" is equal to 2. So the derivative of x2 is equal to 2x.
What is the equation for the reaction between cyclohexane and sodium hydroxide?
The reaction between cyclohexane and sodium hydroxide involves hydrolysis of cyclohexane to cyclohexanol and cyclohexanone. It can be represented by the equation: C6H12 + NaOH → C6H11OH + NaX (where X is an anion)
What is the definition of the math term differentiation?
It is how you find the gradient of a curved line. To differentiate, you take the x's power, multiply by the x, and take one off the power. The common equation for this is: y = axn goes to dy/dx = nax(n-1)
When is the nax lunar eclipse?
The next total lunar eclipse will occur on December 21, 2010, and will be visible from anywhere in North America.
