Write a balanced equation for the reaction of Al(H2O)6^3+ in aqueous KF. Include physical states for each reactant and product in the equation.
Consider the titration of 30.0mL of 0.050M NH3 with 0.025M HCl. Calculate the pH after the following volumes of titrate have added.
Provide the structure of an aromatic compound with seven carbon atoms. Draw the molecule on the canvas by choosing buttons from the Tools (for bonds)
The volume of a 24.0g sample of methane gas is 22.8L at 40.0*C and 4.00atm. What will it's volume be at 68.0*C and 4.00atm.
How should the two heats of reactions for the neutralization of NaOH and the two acids compare? Why?
Calculate ?Sºf for oxalic acid and ?Sº for the combustion of one mole of oxalic acid. c) Calculate ?Gºf for oxalic acid and ?Gº for the combustion of one mole of oxalic acid.
After running the reaction for some time, we collect the product and find a total of 3.1 x 10-3moles of COOH groups. What is the molecular weight of the material? Extent of reaction?
Hydrogen is produced when methane(CH4) reacts with water. The other product is CO2. Using 80.0g of methane and 16.3g of water, how many liters of H2 can be produced at STP? what is the limiting reactant?
The following is a first order reaction with a rate constant of 2.98*10>-3s-1: SO2CL2>>>>SO2+CL2. What is the half life for the reaction?
Show all long pair electionrs (this means even those unreactive lone pairs), proper mechanistic arrows, all intermediate steps, and all side reactions if any. If you write them by hand please write clearly so I can understand everything.
Draw a schematic of the flow. Clearly define and label the axes and any variables to be used. Indicate on the schematic the fluid on top and bottom of the slit.
titrating an unknown weak acid you hope to identify. Your titrant is a 0.0935 mol/L NaOH solution, and the titration requires 21.8 mL to reach the equivalence point. How many moles of acid were in your sample?
