State the Arrhenius, Bronsted-Lowry, and Lewis definitions of acids and bases. Given an acid-base reaction equation, pick out the acid, base, conjugate acid, and conjugate base. Know the definition of conjugate acids and bases. Describe what is meant by an amphoteric species. Write the equation for the self ionization of water and know the ion product constant expression for water and its value at 25 degrees. Know the difference between reactions going to completion () and reactions reaching an equilibrium condition ( ). Define what is meant by pH and pOH. How are they related?
Determine how much PV work is done if 80.0 g of C 2 H 4 and 125 grams of hydro chloric acid are permissible to react at atmospheric pressure and the volume change = -63.9 L? express your answer in kilojoules
Let's say that you are given a 0.215g of unknown weak acid and asked to dilute with 75 mL of DI water. You then use a standardized 0.125 M NaOH to titrate the unknown acid solution
How many liters of it are required to decompose the organic matter in 1.00 liter of wastewater with a biological oxygen demand (BOD) of 137 mg per liter
The Al2O3 does not react. If the sample residue weighs 2.675 g, what is the mass fraction of Fe2O3 in the original sample?
Lead(II) sulfide was once used in glazing earthenware. It will also react with hydrogen peroxide (H2O2)to form lead(II) sulfate and water. How many grams of hydrogen peroxide are needed to react completely with 265 g of lead(II) sulfide?
Draw graphs representing Boyle's law, Charles's law, and Gay-Lussac's law for a fixed amount of gas. Make sure that you label each axis and state the assumptions for each law-that is, the variable(s) that is (are) held constant for each law.
Compute the pressure of the system express your answer in kPa. suppose the force of gravity = 9.81 m/sec^2 , density of mercury =13600 kg/m^3.?
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good.
The solute increases the volume of the solution, and an increase in volume requires an increase in the temperature to reach the boiling point (derived from PV = nRT).
What mass of calcium can be produced by this process if a current of 5900 A is applied for 55 h? Assume that the electrolytic cell is 60 % efficient.
A gas occupying a volume of 263 mL at a pressure of 0.970 atm is allowed to expand at constant temperature until its pressure reaches 0.541 atm. What is its final volume?
Dibenzoylmethane is not a methyl ketone, but it gives a positive result in the iodoform test when treated with NaOH and I2. Explain this result.
