The experiment involves reactivities of alkyl halides. Explain what is the soluble product of reaction between silver nitrate as well as 2-bromo-2-methylbutane. Is this a SN1 or SN2 reaction-explain?
What is the age of the wine in the glass on the left, and the glass on the right? b. What assumption(s) do you have to make in order to compare their tritium counts?
Which of the following has the smallest mass?
A beaker of nitric acid is neutralized with calcium hydroxide. Write a balanced molecular equation and a net ionic equation for this reaction.
The cup is a volume widely used by cooks in the U.S. One cup is equivalent to 237 cm^3. If 1 cup of olive oil has mass of 216 g, what is the density of olive oil in g/cm^3?
Reactions of alcohols with hydrogen halides yield the important class of compounds known as alkyl halides. Reactivity towards the hydrogen halides
Compute the expected pH when 0.5 mL of 0.1 M HCL is added to 30.0mL pure water. Do the same computation when the same amount of HCl is added to 30.0mL of your original .05M buffer. Compare the Computed pH to the actual measured pH
Consider the decomposition of calcium carbonate. Assume that ?H° = 177.8 kJ/mol and ?S° = 160.5 J/K·mol for the temperature range. CaCO3(s) -> CaO(s) + CO2(g)
Consider an amphoteric hydroxide, M(OH)2(s), where M is a generic metal. M(OH)2 (s) M^2+ (aq) + 2OH- (aq) Ksp=2e-16 M(OH)2 (s) + 2OH- (aq) M(OH)4 ^2- (aq) Kf=0.03 Estimate the solubility of M(OH)2 in a solution buffered at pH= 7.0, 10.0, and 1..
consider the reversible reaction of carbon monoxide and water vapor yeilding carbon dioxide and hydrogen.
When NH3 is added to a saturated solution of AgCl in which undissolved AgCl is present, the reaction that occurs is a) AgCl(s) + 2NH3(aq) AgNH2(aq) + NH4Cl(aq)
A solution of 0.1% sodium dodycl sulfate (SDS) binds so strongly to polypetide chains that one detergent molecule is sufficient to saturate two amino acid residues.
