Assume that you start with 0.557 g of copper turnings and the initial number of moles of Cu is 8.77×10-3 mol.The minimum volume of 16.0 M HNO3 required to dissolve all of the copper is 2.19 mL.
If, in practice, 5.0 mL of 16.0 M nitric acid were added to effect the dissolution of the copper, what would be the minimum volume of 4.00 M NaOH required to neutralize the remaining acid and convert all of the Cu2+(aq) to Cu(OH)2(s)?
Calculate the minimum volume of 1.00 M H2SO4 required to dissolve all of the CuO(s)
Calculate the minimum mass of zinc required to reduce all of the Cu2+(aq)to Cu(s)(Note that, in practice, a significant excess of zinc is used due to loss of H2(g).)
If a 2.1 L reaction vessel initially contains 723 torr of cyclopropane at 485 degrees C , how long will it take for the partial pressure of cylclopropane to drop to below 105 torr ?
Draw the skeletal structure for trans-1-ethyl-4-iodocyclohexane. Make sure the tapered end, i.e. the thin end, of the wedge bond is attached to the parent.
Write the standard half-cell reduction reaction equation for reactive species in the beaker. B) Determine the cell potential(Ecell) at the moment of mixing.
Consider the combustion of ethane 2C2H6 + 7O2 yields 4CO2 + 6H2O If the ethane is burning at the rate of 0.1 mol/L*s, at what rates are CO2 and H2O being produced?
Will the yeast cells or the corn seedling have a higher metabolic rate when compared on a mass specific basis (in moles ATP/gram organism x hr)?
A sample of gasoline contains various hydrocarbons, which comprise atoms of carbon, hydrogen, and oxygen. The hydrocarbons mix together uniformly to form gasoline.
The principle quantum number defines the shell (which is roughly, but not quite exactly, the row, or period, of the periodic table). Demonstrate the difference between the rows of the periodic table
Construct a pie molecular orbital system for the nitrate radical (NO3), using the appropiate 2p orbitals. (b) what is the ground electronic state of this molecule?
