Describe the preparation of 1.50 L of a solution that is 12.0 ppm in K+, starting with solid K4Fe(CN)6.
8.5 g of steam at 373 k is added to 305 g of h20 l at 310 k at constant pressure of 1 bar. is the final state of the
Chlorination via radical halogenation is a very unselective process and can lead to the formation of all three of the below products. Estimate the relative percentages of each product that will be formed using this means of halogenation. Presume t..
calculate the gasphase proton affinity of NH3. The lattice energy of NH4Cl may be estimated from Kapustinskii's formula using rN-Cl = 3.50 Å.
Background: Lake Lianna is fed by two rivers, the Matthew and the Andrew. You have made careful water chemistry measurements throughout the year and found that the two rivers have the following pH and alkalinity
The reaction S2O82- + 2 I- ------> 2 SO42- + I2 proceeds slowly in aqueous solution, but can be catalyzed by the Fe+3 ion. Given that Fe+3 can oxidize I- and Fe2+ can reduce S2O82-, write a plausible two-step mechanism for this reaction.
