At a particular temperature, K = 1.00×102 for the reaction:
H2(g) + F2(g) 2HF(g)
In an experiment, at this temperature, 1.90 mol of H2 and 1.90 mol of F2 are introduced into a 1.25-L flask and allowed to react. At equilibrium, all species remain in the gas phase.
What is the equilibrium concentration (in mol/L) of HF?
To the mixture above, an additional 9.50×10-1 mol of H2 is added.What is the new equilbrium concentration (in mol/L) of HF?
compound has been analyzed and found to contain the following masses of elements: Carbon 0.2990g, hydrogen 0.05489g, nitrogen 0.2318g, and oxyen 0.1328g. calculate the tmpirical formula of the compound.
which element has the greatest density at STP? and why?
Calculate the expected pH values of the buffer systems from the experiments (a, b, c, d) using the Henderson-Hasselbalch equation (pH= pKa + log [A-] ). Use for pKa values: carbonic acid= 6.37 and acetic acid= 4.75.
