When two atoms form a covalently-bonded diatomic molecule, the distance between the nuclei at which the potential energy is at a minimum is called
An intermediate in a chemical reaction is a species that the reactant molecules interact with during an early step in a reaction that is regenerated
a gas cylinder witha volume of 3.00 dm^3 contains 8.00 moles of oxygen gas at a temperature of 50.0k. what is the pressure inside the cylinder.
if a sample of gas at 25.2 C has a volume of 536 mL at 637 torr, what will its volume be if the pressure is increased to 712 torr.
Bromine can be obtained from the decomposition of calcium bromide by means of electrolysis. If 10.0 g of calcium bromide are dissolved in water
Since most potassium salts and nitrates are soluble in water, PbCrO4 must be the precipitate. The equation for this reaction is: Pb2+ + CrO4 2- -> PbCrO4. Calculate the theoretical yield using the starting quantities of both reactants.
