At a certain temperature, the equilibrium constant, kc, for this reaction is 53.3. h2(g)+i2(g)â½âââ2hi(g)kc=53.3 at this temperature, 0.700 mol of h2 and 0.700 mol of i2 were placed in a 1.00-l container to react. what concentration of hi is present at equilibrium?

In which phase(s) do the molecules take the shape of the container?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Which statement best describes isomers? a. isomers are alcohols that have the same functional group. b. isomers have at least one carbon-carbon double bond. c. isomers have the same molecular formula but different structural properties.
