    A safety audit for the gas-solid fluidization experiment was conducted. The following safety concerns were found when performing the audit: operating beyond the operating limits‚ spillage of the beads‚ risk of head injury from bending over to change the beads in the apparatus or from the low bar‚ and congestion of the workspace. One of the biggest safety concerns with this lab involved the small glass beads that acted as the solid in the experiment. If the gas flow rate goes below 50 standard cubic

    constant. Use potassium chloride with a known conductivity as a standard solution. The conductivity measurements are not appropriate to compare between two electrolyte solutions because of the high dependant towards solution concentration. The molar conductivity (Λm) measurements would be more appropriate. Λm could be determined from the conductivity value: [pic] where C is the electrolyte concentration In mol/L. the unit is S cm2mol-1 If the dependant of conductivity towards concentration

    carbonate until 250 ml of solution were made. I had to calculate‚ from the information provided‚ how much sodium carbonate to use in the making of the solution. Using the volume and concentration of the solution‚ I was able to calculate the moles of the solution (concentration x volume). Using the periodic table I was able to calculate the molar mass of sodium carbonate which was 106‚ from this I could calculate the mass of the sodium carbonate I needed to make the solution (moles x Mr). After making the

    Review the behavior of the gas phase vs. the liquid phase. Solution: a) The volume of the liquid remains constant‚ but the volume of the gas increases to the volume of the larger container. b) The volume of the container holding the gas sample increases when heated‚ but the volume of the container holding the liquid sample remains essentially constant when heated. c) The volume of the liquid remains essentially constant‚ but the volume of the gas is reduced. The particles in a gas are further apart than

    Academy A mole is a scientific unit developed by chemist that measures large quantities of very small things‚ such as atoms‚ molecules‚ and other particles. There are three types of molar conversions; moles to particles or particles to moles‚ moles to mass or mass to moles‚ and moles to volume or volume to moles. The number of units in a mole is 6.02 × 1023. This number is called Avogadro’s number in honour of Amedeo Avogadro. Full name‚ Lorenzo Romano Amedeo Carlo Avogadro was an Italian
