Briefly explain how you would alter the calibration curve technique to determine the concentration of glucose in a urine sample.
A buffer is made with 25mL of 1.0 M HC2H3O2 and 25mL of 1.0 M NaC2H3O2. Calculate the theoretical pH. I know the pH is 4.74.
Calculate the pH for an aqueous solution of acetic acid that contains 3.15 × 10-3 M hydronium ion.
I need help in describing the adverse effects caused by exposure to radiation. Include some specific exposure levels associated with these significant health effects.
What is the wavelength of light required to induce a transition from the ground state to the first excited state?
Calculate the amount of heat (in kJ) required to raise the temperature of 242 grams of water from 24 degree C to 65 degree C.
Using the following data, calculate the standard enthalpy of reaction for the coal gasification process 2C(s) + 2H2O(g) --> CH4(g) + CO2(g).
Describe clearly why a single indicator solution in only useful for measuring pH over a rather narrow range. Use a specific indicator of solution
The molar enthalpy of fusion of ice at 0 0C is 6.02 kJ/mol; the molar heat capacity of supercooled water is 75.3 J/molK. (a) One mole of supercooled water at -10 0C is induced to crystallize in a heat-insulated vessel.
2 mol of a compound is allowed to react in a foam coffee cup that contains 101 grams of water. the reaction caused the temperature of the water to rise from 21 to 24.7 C. What is the enthalpy of the reaction?Assume that no heat is lost to the surr..
If the temperature of a sample of gas with an initial volume of 1.75 is increased form 15.0 c to 30.0c, what will the final volume be.
What is the rate of reaction of O2? What is the rate of formation of N2O5?
For caffeine, the partition coefficient between methylene chloride and water is approximately 8. If you add the following to a separatory funnel - 10 g caffeine,
