Consider four different samples: aqueous , molten , aqueous , and molten . Current run through each sample produces one of the following products at the anode: liquid bromine, fluorine gas, or oxygen gas. Match each sample to its anodic product.
If 352 g of magnesium reacts with excess oxygen to produce 296 g of magnesium oxide, what is the percent yield for the reaction?
A fixed quantity of gas at 21 exhibits a pressure of 730 and occupies a volume of 4.40. Use Boyle's law to calculate the volume the gas will occupy if the pressure is increased to 1.85 while the temperature is held constant.
Use a table of standard thermodynamic values to predict the standard cell potential at 81 C: Cu(s)|CuSO4||AgNO3|Ag(s) Assume that the values of delta H and delta S are independent of temperature.
Draw a Lewis structure for H3C-NO2. Both oxygen atoms are directly attached to the nitrogen atom. If you take formal charge considerations into account, how many -bonds are in the molecule?
determine the volume occupied by .582 moles of a gas at 15*C if the pressure is 622 mm Hg?
a buffer solution is prepred by adding 15.00g of sodium acetate (NaC2H3O2) and 12.50g of acetic acid to enough water to make 500mL (three significant figures) of solution.
used the 8900 kilojoules you expend in energy in one day to heat 50000 of water at 20 what would be the rise in
Sulfamic acid, HSO3NH2, and sodium nitrite, NaNO2, should not be brought together as solids for safety reasons, why is water added to the vial containing your unknown sample as well as to the Erlenmeyer flask containing sulfamic acid
What is the density (in g/L) of a mixture of equal numbers of moles of N2 and CO2 gas in a 8.00 L container at 298K if the pressure exerted is 19.0 atm
Describe how you would prepare 500 mL of 1.75 M HCl solution starting out with an 8.61 M stock solution of HCl.
how do you do the lewis dot structure for NBr3 and H2O? we have to do it on Marvin sketch if any of you are familiar with it. thanks so much
consider the following reaction: 2 A(g) + B(g) 3 C(g) + D(g) Please determine Kc if 6.0 moles of A is added to 6.0 moles of B in a 2.0 L yields 0.10 moles of D at equilibrium.
