Suppose 0.916 g of potassium bromide is dissolved in 100.mL of a 49.0mM aqueous solution of silver nitrate. Calculate the final molarity of bromide anion in the solution. You can assume the volume of the solution doesn't change when the potassium bromide is dissolved in it.Round your answer to 3 significant digits.
The membrane permeable only to Na^+ ions is used is used to separate the following solutions: 0.03M KCl and 0.070M NaCl and 0.070M KCl and 0.03M NaCl. Calculate the membrane potential at 298K.
Exactly 1.0065 g of an unknown solid containing Fe2(SO4)3 and non-ionogenic impurities was dissolved in about 25 mL of wate
You get curious as you are weighing out the 2.25 moles and wonder how many molecules are there in your 2.25 moles of Sodium Bicarbonate sample. What is the molecular Mass of Sodium Bicarbonate?
Corrosion is a leading cause of structural degradation of bridges and roadways. Not only does rust weaken metal structures, but as it builds up it forces apart connecting parts of the structure, causing the structure to fail and risking public safety..
Sulfurous acid, H2SO3, is a weak diprotic acid (pKa,1=1.89 and pKa2 =(7.21 at 25oC). What is the pH of 0.121 mol/L H2SO3(aq) at 25oC?

Compute deltaS values for the subsequent reactions by utilizing tabulated So values from Appendix C. (a) Cl2(g) + H2(g) 2 HCl(g) So deltaS = J/K (b) Be(OH)2(s) BeO(s) + H2O(g) So deltaS = J/K (c) SO2(g) + 1/2 O2(g) SO3(g) So deltaS = J/K (d) NH3(g..
