Using the calculation you performed in your Pre-Lab in Microsoft Excel, generate a plot of absorbance @ your chosen wavelength (the wavelength that provides the best data for your purposes) vs. [indicator].
It only contains only C,H, and O. A 116mg sample was treated with an excess of methylmagnesium bromide, producing 48.7ml of methane gas at 20 degrees C and 750mm Hg.
we will provide a standard solution of 0.100 m nacl and a solution of 20-fold diluted tonic water the unknown for your
Glycolysis is an example of anabolism or catabolism ?
The solubility of nitrogen in water exposed to the atmosphere, where the partial pressure of nitrogen is 593 mm, is 5.3 × 10-4 M. At the same temperature, what would be the solubility of pure nitrogen, at a pressure of 760 mm?
Metformin is used to treat Type II Diabetes. It is excreted in the urine with no metabolism from the liver with a half-life of 5 hours. Average Volume of Distribution of Metformin is 654 L for a dose of 850 mg.
estimate the enthalpy change for the reaction between 1 mol c2h5oh as liquid ethanol, a fuel made by fermenting corn, and o2 to yield co2 and h2o under standard conditions by using bond enthalpies,
Identify the nuclide produced when fluorine-18 decays by positron emission:18/9F->0/1e+ Identify the nuclide produced when thallium-201 decays by electron capture: 201/81Tl+0/-1e->0/0radiation+
For each of the following ions identify the neutral atom that has the same number of electrons and determine if this atom has the same electron configuration. If such an atom does not exist explain why: (a) Cl-, (b) Sc3+, (c) Fe2+, (d) Zn2+, (e) S..
Tests on a sphere are conducted in a wind tunnel at an air speed of U0. the velocity of flow toward the sphere along the longitudinal axis is found to be u=-U0(1-r0^3/x^2) where r0 is the radius of the sphere and x is the distance from its center.
A buffer is made by combining 3.50 L of 0.200M butylamine, C4H9NH2 with 7.50L of 0.100M butylammonium chloride, C4H9NH3Cl. Assuming that volumes are additive
How long will it take for a signal to travel that distance assuming that the speed of light in the cable is the same as in a vacuum?
In a separate experiment, it was found that, for fixed temperature and pressure, a 0.100 L sample of this compound takes 1.73 times longer to effuse than does a 0.100 L sample of Ar(g). What is the molecular formula of the compound? For bonus mark..
