A copper problem Question 1 When copper is exposed to air for a long time, it "tarnishes" which means its surface becomes reddish as it forms a copper oxide coating. It was found that 0.8897 g of copper formed 1.0017 g of the red copper oxide. (a) Use these data to determine the empirical formula of this copper oxide. (Cu20) (b) What is the charge on the copper ion in this compound? (+1)

Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.
