Determination of the Alcohol Content of Beer by Gas Chromatography
1. In gas chromatography (G.C.), what is the purpose of injecting the sample onto a heated block?
2. The G.C. that you will be using uses a flame ionization detector and requires two gases, hydrogen and helium. What are the specific roles of each of these gases?
3. The FID detector is a very sensitive detector. How sensitive is this type of detector?
4. What is the objective of adding 1-propanol to each standard and sample?
Fluoride ion selective electrodes obey the following equation: What is the value of K and m
How much heat (in kilojoules) is evolved or absorbed in the reaction of 2.45 of with enough carbon monoxide to produce iron metal?
A solution is prepared by dissolving 0.19 of acetic acid and 0.19 of ammonium chloride in enough water to make 1.0 of solution. What is the concentration of Ammonia in the solution
The antifreeze in a car was a 50% by weight solution of ethylene glycol C2H6O2 in water. Calculate the boiling point and freezing point of this solution. (for H2O: Kb= 0.52 C/m... Kf=1.86 C/m
The resultant mixture is then evaporated in a kettle to produce a jam contain- ing 67 wt % soluble solids
Problem- A saturated solution of carbon dioxide in water contains .0682 mol/L of CO2 when the CO2 partial pressure is 8.0 atm. 1) What mass of CO2 will escape if the partial pressure is lowered to 3.2 atm? CO2 MM= 44 g/mol
For a copper zinc cell of sulfate concentration 1M the potential is see to be 1.10 volts. Calculate the potential of the cell at room temperature if the concentrate of zinc sulfate is 1.2 M and the concentrate of copper sulfate is 0.0012 M.
Calcium carbide, CaC2, reacts with water to form acetylene. CaC2(s) + 2 H2O(l) -> C2H2(g) + Ca(OH)2(s)
The enthalpy of formation of MX2 is ?Hf° = -829 kJ/mol. The enthalpy of sublimation of M is ?Hsub = 117 kJ/mol. The first and second ionization energies of M are IE1 = 717 kJ/mol and IE2 = 1433 kJ/mol.
