Determine the maximum number of moles of SO2 produced from 12 moles of H2S and 4.0 moles of O2
Lewis Bases given their lone pairs on the central atoms, however, none of them actually are. Why are OF2 and SF4 are strong Lewis Acids and not Lewis Bases
What is the total number of moles of electrons transferred in this reaction: 2 C7H16O + 21 O2 = 16 H2O + 14 CO2? What is the oxidation and reduction pathway?
A 50.0-L stainless steel container was charged with 3.00 atm of hydrogen gas and 4.00 atm of oxygen gas. A spark ignited the mixture, producing water.
A sample of chlorine gas at a pressure of 420 mm Hg and in a volume of 3.50 L was heated from 18.0oC to 45.0oC after being transferred to a container of volume 2.35 L. The pressure in this new container should be about
