Document Summary
The method of the gas chromatography and the mass spectrometry is used to identify the unknown compound. The gas chromatography was used to identify the solvent by separating the compound into individual components using the retention time difference. The mass spectrometry was used to identify the solute by analyzing the mass of pure element and fragments, which is ionized by the electron. Copper (11] can be precipitated from solution using sodium hydrogen phosphate (na2hp04]. 2cn- +-50cl-(aq) + h2o (l) n2(g) +2hco3- (aq) + 5cl- ;how many liters of 0. 125 m. 3. 4(10^6)(0. 58)(1/1000)(1/26. 02)=75. 8 mol cn- , 75. 8(5/2)(1/0. 125)=1516 l of. An individual atom does not possess a state of matter. Rather, it is the arrangement of atoms relative to one that prescribes a particular state of matter for the element at hand. A solid has atoms that are tightly packed and are not compressible. A liquid has atoms that are touching but still retain the ability to move freely.
