Would you be able to use a similar approach to identify a mixture of two or three elements with emission spectrum analysis? Why or why not? the similar approach is: "Magnesium metal burns with a bright white flame. What conclusions can you draw about the electron transitions that can take place for a magnesium atom?

The conclusion that you can draw about the electron transitions that can take place for a magnesium atom is that the photons produced are not of a lone wavelength, therefore from many dissimilar levels to subsequent levels, with many different wavelengths joining to create white."

The scheme below is from a series of reactions that are part of a synthesis of vitamin a. answer the following questions with reference to this scheme. (i) what is "reagent a"? (ii) draw a step-by-step mechanism which explains the formation of compound c from compound b (iii) which reagents would you use to form compound e from compounds c and d (reagents b and c)? for each reagent suggested above in (ii) explain the role of the reagent in the reaction to (iv) form compound e. you may wish to do this by drawing a mechanism. 1. addition of reagent a но reagent a 2. н,о" thо oh нон-с compound a. compound b. compound c .ch-оh 1. reagent b "сно 2. reagent c сh oh compound e. compound d.

Substance a is a nonpolar liquid and has only dispersion forces among its constituent particles. substance b is also a nonpolar liquid and has about the same magnitude of dispersion forces among its constituent particles. when substance a and b are combined, they spontaneously mix.
