Solid Lithium hydride is added to water. Find the complete molecular, complete ionic, and net ionic formulas.
You mix 50 ml of a weak monoprotic acid with 50 ml of NaOH solution in a coffee cup calorimeter. Both solutions and the calorimeter were initially at 22 C.
Giving examples give the mechanisms of Aldol condensation between two molecules of aldehydes and two molecules of ketones
when a stip of zinc metal is placed in a blue aqueous solution of copper (II) sulfate, the surface of the zinc becomes coated with a reddish solid, and the zinc begins to dissolve to form aqueous zinc sulfate. Which of the following statements reg..
calculate the volume that a 0.323 -mol sample of a gas will occupy at 265k and a pressure of 0.900atm
high boiling point are obtained now you need to identify the limiting reagent and compute the percent yield of nitrobenzene
NMR of D exhibits resonance at -4 ppm. - On heating D, a flammable gas and A are formed. - Reaction of C with CH3I affords white solid E whose proton NMR shows a single resonance around 0.2 ppm. Identify A-E.
Explain why water boils at a lower temperature (
Determine the pH and the percentage of fully protonated weak acid/base for each of the solutions listed below:
what the molarity of H2SO4 if 15.85 mL of the solution is needed to neutralize 1.00g NaHCO3 molar mass 84.01 g/mol
An aqueous solution contains 12.5% NaCl by mass. What mass of water (in grams)is contained in 2.5L of the vapor above this solution at 55 celcius? the vaor pressure of pure water at 55 celcius is 118 torr.
Zinc citrate (Zn_3(C_6H_5O_7)_2) is an ingredient in toothpaste. It is synthesized by the reaction of zinc carbonate with citric acid. 3ZnCO_3(s) + 2C_6H_8O_7(aq) ---> Zn_3(C_6H_8O_7)_2(aq) + 3H_2O(l) + 3CO_2(g).
7.50 mL of 0.125 M HCl is added to the 100.0 mL of the buffer solution. Calculate the new [NH3] and [NH4Cl] for the buffer solution. Calculate the new pH of the solution.
