Predict what product favored reaction will occur when potassium metal is dropped into liquid water. Write a balanced chemical equation for the process and explain breifly how you made your predicition.
Like sulfuric Acid, a certain diprotic acid, H2A, is a strong acid in its first deprotonation and a weak acid in its second deprotonation. A solution that is 0.020 M H2A (aq) has a pH of 1.66. What is the value of Ka2 for this acid
Sulfamic acid (FM 97.094) is a primary standard that can be used to standardize NaOH. What is the molarity of a sodium hydroxide solution if 38.92 mL react with 0.3341 g of sulfamic acid
in a strongly acidic solution the amino acid lysine esists as the dication. as the pH is raised, what monocation is formed by the loss of a proton form the dication?
An aqueous solution containing 21.6 mg of vasopressin in 100.0 mL of solution has an osmotic pressure at 25.0 oC of 3.70 mmHg. What is the molecular weight of the hormone?
A 30.0 mL sample of a diprotic acid is titrated with 0.255 M KOH. If 59.5 mL of base is required to reach the second equivalence point
Calculate the hydronium concentration for a solution prepared by dissolving 0.15 mol of benzoic acid (C6H5COOH) and 0.30 mol of sodium benzoate (C6H5COONa) in 1.00 L of solution. (Ka of C6H5COOH = 6.5 x 10-5)
What enone product would you expect to obtain from intramolecular aldol condensation of 5-oxohexanal
When aqueous solution of sodium sulfate and lead nitrate are mixed, lead sulfate precipitates. Calculate the mass of lead sulfate produced when 1.25 L
This equation means that no matter how much carbon monoxide and oxygen gas is added to the flask, only 2 moles of CO and 1 mole of O2 will react to make two moles of Co2.
Calculate the cell potential for the following reaction that takes place in an electrochemical cell at 25°C. Cu(s) | Cu2+(aq, 0.0032 M) || Cu2+(aq, 4.48 M) | Cu(s)
The MnO4(-) is often used to analyze for the Fe(2+) content of an aqueous solution via the reaction MnO4(-)+Fe(2+)---> Fe(3+)+Mn(2+) in acidic solution. What is the ration Fe(2+):MnO4(-) in the balanced equation
