Calculate the change in pH when 6.00 mL of 0.100 M HCl(aq) is added to 100.0 mL of a buffer solution that is 0.100 M in NH3(aq) and 0.100 M in NH4Cl(aq).
Calculate the change in pH when 6.00 mL of 0.100 M NaOH(aq) is added to the original buffer solution.
Suppose that Part II of the experiment were carried out with aqueous NaOH (sodium hydroxide) instead of Ba(OH)2 to form soluble Na2SO4
What is the mass of a rectangular piece of copper 24.4cm x 11.4cm x 6.6cm? The density of copper is 8.92 g/cm^3.
Calculate the [H3O+], pH, and the fraction of dissociation (α) in an aqueous 0.140 M NH3 solution. (Hint: You will need the Ka, located in the back of your textbook.)
The (-) enantiomer of a compound has a specific rotation [a]= -86 degrees. A sample of this pure enantiomer, when measured in a two dm sample tube, gives an observed rotation
what is the total number of grams of patassium chloride needed to saturate exactlye 300 grams of water at 10 degrees celcius?
Geologists can estimate the age of rocks by their uranium-238 content. The uranium is incorporated in the rock as it hardens and then decays with first-order kinetics and a half-life of 4.5 billion years
Predict the outcome of the following reactions represented by the following equations by using the activity series, and balance the equations.
