Suppose you have the following reagents available under standard conditions. (i.e., P = 1 atm for all gases; t = 25 oC; C = 1 mol L?1 for all aqueous species, including H+.) Co(s), Ag+(aq), Cl?(aq), Cr(s), BrO3?(aq), I2(s), F?(aq) Consult the standard reduction potentials on the next page and then answer the following questions. (a) Which is the strongest oxidizing agent? (b) Which is the strongest reducing agent? (c) Which of the available reagent(s), if any, will oxidize Fe(s) while leaving Cu(s) unreacted? If none of the available reagents can be used for this purpose, then identify another reagent from the table that could be used. For each reagent you've identified, write down a balanced chemical equation for the reaction that occurs.
In combustion studies of the use of H2 as an alternative fuel, HO is sometimes formed in flames by the reaction, H(g) + 1/2 O2(g) HO(g) Use the data below to calculate the value of Kc
Calculate the expectation value for the kinetic energy of the H atom with the electron in 2s orbital. Compare your result with total energy
The half-life of a certain radioactive element is 1,250 years. What percent of the atoms remain after 7,500 years?
A certain substance, intially present at 0.500 M, decomposes by second-order kinetics with a rate constant of 4.00 x 10-1 L/mol min. Calculate the time (in minutes) required for the system to reach a concentration of 0.370 M.
Hydrogen bromide adds to the triple bond with a regioselectivity dictated by Markovnikov's rule. One mole of HBr adds to one mole of 1-heptyne.
which of the following alkyl halides reacts most rapidly via SN1 solvolysis reaction in hot methanol? A) 1-iodo-1-methylcyclohexane
A certain complex of metal M is formulated as MCl3*3H20. The coordination number of the complex is not known, but is expected to be 4 or 6. would reaction of the complex with AgNO3(aq) provide information about the coordination number?
Using the van der Waals equation, calculate the pressure exerted by 15.0 mol of carbon dioxide confined to a 3.00-L vessel at 56.0 oC. Note: Values for a and b in the van der Waals equation: a = 3.59 L2.atm/mol2, and b = 0.0427 L/mol.
Draw a representation of the 3-D structure of the anion, including only the bonding-pair electrons, and any sulfur lone-pair electrons. What is the orientation of the oxygen atoms with respect to each other around the S?S bond?
How do moles of hydrogen gas are produced for every mole of solid magnesium reacted
A gaseous fuel mixture stored at 752 mmHg and 298 K contains only methane and propane . When 11.6L of this fuel mixture is burned, it produces 767kJ of heat methane : 890 kJ/mol propane : 2,220 kJ/mol
The heat of formation (?H°f) of MgCO3 (s) is -1095.8 kJ/mol. The chemical equation associated with this reaction is: MgO (s) + CO2 (g) ? MgCO3 (s) Mg+ (s) + CO3- (s) ? MgCO3 (s) Mg (s) + CO3 (s) ? MgCO3 (s) Mg (s) + C (s) + 3/2 O2 (g) ? MgCO3 (s) ..
