Graphite Furnace vs ICPwith investigating and writing a proposal for Heavy metal testing using Graphite Furnace. This will include capabilities, limitations and costs (possibly cost comparison with ICP).
The air in an inflated balloon (defined as the system) warms over a toaster and absorbs 121 J of heat. As it expands, it does 70. kJ of work. What is the change in internal energy for the system.
If you take a 10.5mL portion of the stock solution and dilute it to a total volume of 0.350 L, what will be the concentration of the final solution.
A sample containing 2.40 {rm moles} neon gas has a volume of 8.00 {rm L}. Assume that the pressure and the temperature remain constant.
Calculate molarity?if one mole of sodium hydroxide was dissolved estimate the number of calories that would be produced. (ΔHsolnNaOH)
Sodium methoxide CH3ONa is a weaker base than BuLi or nBuLi butyllithium. Recommend an explanation why it is not surprising to find that a weaker base is sufficient to prepare the Horner-Emmons-Wittig reagent.
pH = log[H3O+] , pH + pOH = 14, [H3O+] * [OH-] = 1.0 X 10^-14, pH = -log(0.001) = 3 Could you show me a few of the steps between line one and two in both of these conclusions?
