Mg metal is considered an active metal,in that it spontaneously reacts with an HCl solution.silver(Ag),however,does not react with the HCl solution to any appreciable extent.using the table of standard reduction potentials,briefly explain why this is so.
We most often express heat as kilocalories and kilojoules rather then calories and joules. When 1 pound of fat is burned in the body,9.4 kilocalories of energy is produced. Express that as a) calories b)kilojoules
Propose a synthesis of 1,2-butanediol from ethyne as the only organic starting material. Your ethyne supply may be split to make different intermediates that, in turn
Describe the mechanism of the preparation of 2-methyl-3-hexanol by reducing an appropriate carbonyl compound.
Use the collision theory to calculate the theoretical value of the second-order rate constant (in m3 mol-1 s-1) for the gas-phase reaction D2 + Br2 = 2 DBr at 450 K assuming that it is elementary bimolecular. The collision cross-section for this r..
Calculate the concentration in ppm of a pollutant that has been measured at 450 mg per 150 kg of sample.

it is found that the equilibrium concentrations in a 5.00 L rigid container are [H2] = 0.0500 M, [F2] = 0.0100 M, and [HF] = 0.400 M. If 0.338 mol of F2 is added to this equilibrium mixture, calculate the concentrations of all gases once equilibri..
Calculate the volume of oxygen required to burn 5.00 L of propane gas, C3H8, to produce carbon dioxide and water, if the volumes of both the propane
A beaker with 175ml of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100M .
How many grams of Na3PO4 will be needed to produce 350ml of a solution that has a concentration of Na+ ions of 0.900.
A solution of .162 M NaOH is used to neutralize 25.0 mL of a H2SO4 solution. if 32.8mL of the NaOH solution is required to reach the endpoint, what is the molarity of the H2SO4 solution? H2SO4(aq)+2NaOH(aq)>Na2SO4(aq)+2H2O(l)
