Is the ethoxide anion considered a strong base in elimination and substitution reactions? Could you please explain your answer?
Joe Schmoe mixed peroxide with yeast to generate oxygen gas and collected the gas in a graduated cylinder, using the same set up as was used in Experiment 11. He collected the following data
Calculate the pH of 1.00 L of a buffer that is 0.130 M HNO2 and 0.190 M NaNO2. What is the pH of the same buffer after the addition of 1.00 mL of 12.0 M HCl. (pKa of HNO2 = 3.40)
If the pressure exerted by ozone, in the stratosphere is 3.0*10^-3 atm and the temperature is 253 K, how many ozone molecules are in a liter?
Electronic spectroscopy makes transitions between electronic states, as well as vibrational (and rotational) states. Explain why no general vibrational-state selection rule exists for electronic transitions.
which of the following accounts for the unusually high boiling point of water? the density of water, the hydrogen bonds in water
The sample requires 48.24 mL of 0.08893 mol/L Na2S2O3 to reach the equivalence point. Assuming that the AU3+ and Li+ ions are unreactive during the titration, determine the mass percent of LiCLO in the sample.
Draw out the Lewis structures for H2CO3, HCO3-, and CO32-. Then determine the maximum number of equivalent resonance structures for each species. Note that carbon is the central atom in all three cases
Use the preceding information to predict the value of E for a silver-silver chloride electrode saturated with KCl. For the silver-silver chloride electrode, E° = 0.222 V
The test tube contained some water (besides the metal) that was subsequently added to the calorimeter. Considering a higher specific heat for water, will the temperature change in the calorimeter be higher, lower, or unaffected by this technique e..
Chromic acid is a diprotic acid H2CrO4 with Ka1 = 0.18 and Ka2 = 3.2 x 10-7. A solution of potassium chromate is prepared at pH 5.43. Calculate the fraction of the total chromate in this solution that is present as the chromate ion CrO42-.
Identify which sets of quantum numbers are valid for an electron. Each set is ordered (n, l, ml, ms).
A gas sample is known to be a mixture of ethane and butane. A bulb having a 230.0-cm3 capacity is filled with the gas to a pressure of 97.5 × 103 Pa at 23.1oC. If the weight of the gas in the bulb is 0.3554 g, what is the mole percent of butane in..
