This question is based on the mass spectrum of diethyl sulfide (CH3CH2SCH2CH3) which can be found at this link... http://webbook.nist.gov/cgi/cbook.cgi?ID=C352932&Mask=200 You will need java to see this spectrum! Identify the ion fragment that has a mass of 29.

a) C2H5SC2H5+

b)C4H10+

c) C2H5+

d) S+

Expert Solution

In the given options the Molar mass of C₂H₅⁺ is =(2xAt.mass of C ) + (5xAt.mass of H )

= ( 2x12) + (5x1)

= 29 g/mol

This is the only fragment having mass 29 so the correct answer is (c)

An iron sulfide contains 36.5% S by mass. The iron sulfide is heated in an atmosphere of pure oxygen, which produces SO2(g) and an iron oxide containing 27.6% O by mass. Write a balanced equation for the reaction. If 1.0 kg of the iron sulfide reacts with excess oxygen, what is the theoretical yield of the iron oxide?

1) The emission spectrum of a hollow cathode lamp for molybdenum was found to have a sharp peak at 313.3 nm as long as the lamp current was less than 50 mA. At higher currents, however, the peak developed a cup-like crater at its maximum. Explain. 2) Why does the cathode of the hollow cathode lamp have a cylindrical shape? Why is an element lamp required as the source for AA? Which copper line was used for analysis of copper...
