If 5.00 ml of a solution containing .0400 M iron is placed in a 100.0 ml volumetric flask and filled to the mark with deionized water, what will be the concentration of iron in this new solution?
Suppose you have 1.250g of the original thulium-167 with half life 7.990E + 05. Calculate how much of the original material will remain after 100 s, 1,000 s and 10,000 s.
Calculate the pH of the solution which results from adding 38.54 mL of 0.1012 M KOH to the cyanic acid/cyanate buffer of the previous problem(*). You must show appropriate c

Use the steady state approximation, with O treated as the intermediate, to find an expression for the rate of decomposition of O3, i.e. -d(O3)/dt. (Note, do not set d(O3)/
solution is needed to just neutralize excess acid after 20 mL of HCl was added to 1. g of the antacid, how many moles of acid can the antacid counteract per gram.
Consider a cylinder filled with air with a piston and spring arrangement on top. The external pressure is 1 bar, the initial temperature of the air in the cylinder is 25 C.
