If a certain gas occupies a volume of 14 L when the applied pressure is 7.0 atm , find the pressure when the gas occupies a volume of 3.5L.
Calculate the equilibrium concentration of HC2O4- in a 0.20 M solution of oxalic acid.
At 600 degrees C, the equilibrium constant for the reaction 2HgO(s) --> 2Hg (l) +O2 (g) is 2.8. Calculate the equilibrium constant for the reaction 1/2O2(g) + Hg(l) --> HgO (s)
Determine the number of moles of CO2 that could be produced from the combustion of 0.00993 moles of Benzene
There is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of Magnesium metal consumed in the reaction, therefore moles of H2 evolved = moles Mg consumed and the atomic weight of Mg = weight of Mg consumed..
