Do carbon dioxide and water have the same molecular geometry? If not, what attributes cause these molecules with similar formulas, AB2, to have different geometries?
Most of the solid did not dissolve because the Ksp of ferric hydroxide is very small at 3 x 10^-39. However, when a certain amount of strong acid was added, the entire amount of solid dissolved. Determine the pH of the solution at that point that ..

why are elements such as Hg, As, Bi, Sb and others first converted to their hydrides prior to sample analysis by Atomic Absorption Spectroscopy?
A student combusts 504.96 grams of ethene gas, C2H4. How many liters of CO2 (g) are produced at a pressure of 0.993 atm and a temperature of 295 K? C2H4 (g) + 3 O2 (g)-> 2 CO2 (g) + 2 H2O (g)
write net equations for the acid-base reactions that occur when the given aqueous solutions are mixed. Determine the value of the equilibrium constant. Use single arrows for the extensive reactions (K>1000) but double arrows otherwise.
Calculate the pH of this solution? if we want to lower the pH by one unit of this solution then How many mL of 0.1 M H 3 PO 4 should be added to this solution?
For a certain reaction ?Gorxn = 27.9 kJ/mol. What is the equilibrium constant at 225oC? Remember to convert kJ to J to have consistent units and the temperature to K.
