what are the intermolecular forces between hexane and cinnamic acid and how does this explaine why heane does not dissolve cinnamic acid
What is the pH of the solution created by combining 2.50 mL of the 0.10 M NaOH(aq) with 8.00 mL of the 0.10 M HCl(aq)
PH of solution during titration process, Q1: What is the pH of a 0.35 M solution of a weak acid HA with Ka = 1.41×10^-8?
A zero-order reaction has a constant rate of 1.70×10-4 . If after 65.0 seconds the concentration has dropped to 7.00×10-2 , what was the initial concentration?
By what factor (The factor is the ratio of the rates) does the rate of this isomerization reaction increase as the temperature increases from 256 degree celsius to 297 degree celsius ?
The buret is filled with the NaOH titrant and the initial volume reading is immediately recorded without waiting the recommended 10-15 seconds. However, in part b-1, the 10-15 second time lapse does occur before the reading is made.
Determine the value of the equilibrium constant at this temperature - Ammonium Hydrosulfide NH4HS yields NH3(Ammonia) and Hydrogen sulfide
Change in heat content We write H = Hfinal - Hinitial or for chemical reactions H = Hproducts - Hreactants Given this equation, What sign is H for exothermic reactions? What sign is H for endothermic reactions?
which of the responses includes all of the following that can form hydrogen bonds with water molecules
the properties of pure water that had been boiled and condensed and the properties of pure water that has been frozen and then melted? Explain please.
Considering the molecule HOOH. What happens to the overlap in the σ bond between the 2 O atoms as one hydroxyl group is rotated in a clockwise relative to the other hydroxyl group?
vinegar is a 5.0% solution by weight of acetic acid (CH3CO2H)in water. given that the ph for acetic acid is 2.41, the ka=1.8X10-5 and assuming the density of vinegar to be 1.00g/cm3, what is the percent dissociation for acetic acid in vinegar?
