Part I: Electron Configurations
1. What is the ground state electron configuration of Mercury, Hg?
2. Is Mercury expected to be paramagnetic or diamagnetic? Explain Why.
Suppose that you are going to collect H2 gas produced from the reaction of an acid with a metal such as zinc. This reaction gives off heat, so the tem perature of the solution will increase as the reaction proceeds.
A quantity of C2H4 gas occupies a volume of 100L at 37C and a pressure of 720 mm Hg. Calculate the weight in grams of this gas.
What type of bonding is used between the Cu2+ cation and the SO42- anion, in CuSO4 (ionic, covalent...)? Write an equation for the process of solid CuSO4.xH2O dissolving in water.
zinc metal reacts with yellow crystals of sulfur in a fiery reaction to produce a white powder of zinc sulfide. a
You have a 48.9 g sample of water at the temperature of -60.0 degrees celcius. How much energy is required to: a) heat the ice to 0 degrees celcius
The rate constant for the first order decomposition of SO2Cl2 is 1.37 x 10^-3 min-1 at a certain temperature. If the concentration is initially 0.500 M, predict it after 300 min.
Dimethyl ether, used as a solvent for extraction of organic compounds from aqueous solutions, has a high vapor pressure which makes it a potential fire hazard in labratories in which it is used
a certain brand of antacid chewing gum was sent to the lab for testing and it was found to have 15 by mass of
What are the concentration(grams if a solid is formed) of all species in sol'n when 25.00mL of a 0.15M sol'n of calcium nitrate are mixed with 37mL of 0.65M sodium chloride
time dependencies 20n2o4 undergoes a first-order reactionn2o4 g --gt 2 no2 g.the rate constant for this reaction is 3.0
Calculate G at 27°C for the following reaction when the partial pressure of water is 0.76 atm given that the ?G° is 8.38 kJ. H2O(l) ? H2O(g)
Consider the change in entropy change that occurs when a box of coins that contains a perfectly ordered array of three moles of coins is shaken. Calculate the entropy of the ordered coins, and then calculate the entropy after the box has been shak..
