Calculate the pH of the solution that results upon mixing 20.0 mL of a 0.200 M HCl with 25 mL of.
With reference to relevant clinical analytes, discuss the use of immunoassay within clinical biochemistry.
Hydrogen peroxide (H2O2) decomposes according to the equation H2O2(l) ? H2O(l) + (1/2)O2(g). Calculate Kp for this reaction at 25oC. (Ho = -98.2 kJ/mol, So = 70.1 J/K•mol)
Why do you think we need to convert the calcium carbonate to calcium chloride befoe we do our EDTA titrations? What specific condition in our titrations require this?
Assuming the multiple internal reflections depicted below, what is the effective path length (um) for measurements in which the sample completely covers the crystal's upper face?
The Ka value for acetic acid, CH3COOH (aq) is 1.8x10^-5 M. Calculate the pH OF 3.00 M acetic acid solution. Next, calculate the pH of the resulting solution when 2.501 mL of the 3.00 M acetic acid is diluted to make
What is their role in this reaction? In the case of this particular example that you watched, where would each of these ions have come from?
what was the original total concentration of cesium and the corresponding radioactivity in Ci/L?
Calculate the pH of a solution prepared by mixing 10.0 mL of 0.500 M NaOH and 20.0 mL of 1.50 M benzoic acid solution. (Benzoic acid is monoprotic: it's ionization constant is 6.7 x 10-5)
The reaction AB-> A+b is second order in AB and has a rate constant of 0.0245 M^-1 S^-1 at 25.0 degree celcuis . A reaction vessel initially contains 250.0 mL of 0.108 M AB which is allowed to react to form the gaseous product.
A student mixed 5.00 mL of a nickel(2) chloride solution with 5.00 mL of .100M sodium phosphate and a precipitate formed. How many moles of sodium phospahte were present in 5.00 mL of the solution?
In the following conditions calculate the moles of hydrogen and the pressure in each flask where the volume is negligible. Each flask is originally 275K with .455 mols of hydrogen gas and .7atm of pressure. Then one flask is heated to 500K while t..
