If doing a combustion lab, what is good and what is bad aspect of using acetylene gas as a model? Give two reasons why non-luminous flame is used in school laboratories. How is a yellow flame changed to a blue flame using the air control valve on the Bunsen burner?
Predict which pure substance has the following chemical and physical properties: white solid at room temperature, high melting point, soluble in water, highly conductive when dissolved in water, react Which of the following observations is quantitative? a. The liquid turns blue ...
The temperature of flame varies depending on the substance being burned and the extent to which the fuel and oxidizer have been pre-mixed. One of the lowest is the "safety flame" of a Bunsen burner, to demonstrate it is on — about 572°F (300°C), while the hottest is carbon sub...
In summary, fire is a form of energy that is created when a fuel, typically a hydrocarbon, reacts with oxygen. The yellow color of a flame is due to carbon being heated to incandescence, while the blue mantle surrounding it is the hottest part of the flame where complete combustion of ...
aHowever, there are some discontinuities in the OH mass fraction contours which are not observed in the temperature contours and are due to (local) flame extinction. It has been argued that the OH radical represents the flame behavior better than the temperature . 然而,有一些间断性在温度等高没...
My solid is Green, altho I have seen it turn blue when some of the liquid splashed out and evaporated. I am thinking that the green color is because of residual HCl, is this the case? Many metal ions form complexes in solution.In water, copper ions form the complex ion Cu(H2O)62+....

In commerce, three brands of aniline are distinguished: aniline oil for blue, which is pure aniline; aniline oil for red, a mixture of equimolecular quantities of aniline and ortho- and para-toluidines; and aniline oil for safranine, which contains aniline and ortho-toluidine and is obtained ...
