Consider the titration of a 24.0 mL sample of .175 M of CH3NH2 with .155 M HBr. Determing each of the following:
A. initial pHB. the volume of added acid required to reach the equivalence pointC. pH at 5.0 mL of added acidD. pH at one-half of the equivalence pointE. pH at eq. pointF. the pH after adding 5.0 mL of acid beyond the equivalence point
The proteins are given to you as 10mM solutions in phosphate buffer. You acquire UV-Vis spectra of the solutions to compare to your unknown mixture.
A balloon filled with 39.1 mol of He gas has a volume of 875 L at 0.0 degrees Celsius and 1.00 atm. The temperature is increased to 38.0 degrees Celsius as the balloon expands to 998 L at constant pressure. Calculate delta E for the He sample. C H..
Consider the conductance of the following 0.025 M Solutions.How do I use data to classify each solute as either a nonelectrolyte (NE), a weak electrolyte (WE), or a strong electrolyte (SE)
Hydrogen gas is contained in a one-liter vessel at "STP"(0 degrees Celsius and 1 Std. Atm.). Flourine gas is contained in a second one-liter vessel at the same conditions of temperature and pressure.
An ideal gas originally at .85 atm and 64 degrees C was allowed to expand until its final volume, pressure, and temperature were 94 mL, .60 atm, and 41 degrees C respecitively. What was its initial volume
For the reaction 2N2O5(g) yields 4NO(g)+ O2(g) what is the decomposition of N2O5(g)
A student studied the clock reaction described in this experiment. She set up a reaction mixture by mixing 10mL of 0.010 M KI, 10mL of 0.0010 M Na2S2O3, 20mL of 0.040 M KBrO3 and 10 mL of 0.10 M HCL.
Excess Ag2CO3 is added to an 0.2 M K2CO3solution. Calculate the equilibrium concentration of Ag+ under these conditions.Ksp for Ag2CO3 is 8.1 x 10-12.
A certain first order reaction has a rate constant of 0.0215 s-1 at 24 degrees C. What is the value of rate constant at 70 degrees C if Ea=90.0 kJ/mol.
It is quickly degraded in the atmosphere though reaction with OH• and O3 to form non volatile species which then form particles. These latter ones are responsible for the haze.
A 0.0355 g sample of an unknown molecular compound is dissolved in 1.000 g of liquid camphor at 200.0°C. Upon cooling, the camphor freezes at 157.7°C. Calculate the molar mass of the unknown compound.
