Consider the titration of 43.2mL of .240M HF with .220M NaOH. Calculate the pH at halfway to the equivalence point. Ka = 3.5 * 10^4
System were found to be [N2]=[O2]=0.200 M and [NO]=0.500 M. N2(g) + O2(g) 2NO(g) If more NO is added, bringing its concentration to [0.800 M], what will the final concentration of NO be after equilibrium is re-established?
You need to produce a buffer with pH = 4.1 by dissolving a weighed amount of sodium formate (FW = 68.0072) in 500-mL of 0.45-M formic acid
Determine the standard reaction enthalpy for the partial combustion of methane to carbon monoxide.
A balloon is inflated to a volume of 8.3 L on a day when the atmospheric pressure is 652 mm Hg. The next day, as a storm front arrives, the atmospheric pressure drops to 620 mm Hg
What is the silver ion concentration in a solution prepared by mixing 457 mL of 0.373 M silver nitrate with 475 mL of 0.442 M sodium phosphate?
Ascorbic acid, HC6H7O3, also known as vitamin C, is a weak acid. It is an essential vitamin and an antioxidant. A solution of ascorbic acid is prepared by dissolving 2.00 grams in enough water to make 100.0 mL of solution
A certain reaction A ? products is second order in A. If this reaction is 10.% complete after 20. s, how long would it take for the reaction to be 90.% complete
hydrogen and nitrogen have different molecular weights, so mass fractions will be different than mole fractions.
what is the order of increasing stability: Li2,Li2+,Li2-?
A student adds 8.10 mL of a 0.490 M HCl solution to the beaker. How much will the pH change? The PKa of acetic acid is 4.760.
Analysis with an elaborate instrument indicates that substance A contains two elements. Substance B and substance C react to give a new substance D.
One ecologically important equilibrium is that between carbonate and hydrogencarbonate (bicarbonate) ions in natural water. (a) Th e standard Gibbs energies of formation of CO3
