Write a chemical equation for HF(aq) showing how it is an acid or a base according to the Arrhenius definition? Write a chemical equation for Ba(OH)2(aq) showing how it is an acid or a base according to the Arrhenius definition? Write a chemical equation for HC2H3O2(aq) showing how it is an acid or a base according to the Arrhenius definition? Really need some help with these. I understand most of it but can't come up with the right answers apparently.
which of the solutions included in this experiment could be used to distinguish between the pairs of solutions. In each case, describe the observations you would make and write a net ionic equation for any reaction that would occur.
Determine the expression for the rate of reaction with respect to each of the reactants and products
If 60.0g of Cu metal at 85C were added to 60.0g ethanol at 10C in a calorimeter of heat capacity 30.0 J/K what would the final temperature be assuming no heat losses? cp for Cu= 0.380 J/K/g and Cp for ethanol = 60.0 J/K/mol
consider a major oil spill in a lake ( a prototype situation related to Alaska Oil Spill few years ago and many subsequent spills) Amount of oil spilled is 2.9 mega gram (Mg).
Provide a structure for the following compound: EI mass spectrum: two molecular ions of about equal intensity at m/z = 180 and 182; IR: 1740 cm-1; 1H NMR
Explain why dichloroethene has a boiling point of 60 degrees C while trans-dichloroethene as a boiling point of 48 degrees C. Include drawings of the structures with dipoles in your answer.
curved arrows to symbolize the flow of electrons, white the stepwise mechanism for the acid-catalyzed esterification of p-aminobenzoic acid to ethyl p-aminobenzoate
Write the names of the following compounds
The reaction OH(aq) + HCN(aq) H2O(l) + CN(aq) is first-order in both the OH and HCN concentrations. The rate constant at 25oC is 3.7×10^9 mol^-1 L s^-1
It was later determined that each molecule of the unknown base could accept two protons. What is the molar mass of this unknown compound?
what is the final temperature of the mixed solution? The heat of neutralization is -56.2 kJ/mol. Assume the density and specific heat of the solutions are the same as those for water.
If a car has an EPA mileage rating of 30 miles per gallon, What is this rating in km L-1? 1 liter = 1 dm3, 1 gallon = 3.785 liter, 1 mile = 1.609 km.
