Without looking at your notes, write the balanced half-reactions for the oxidation and reduction processes that are occurring. The solution turns blue , because Cu 2+ is being formed.
28 Μαΐ 2020 · It is prepared by the reaction of pure sand, SiO 2, with carbon at high temperature. Carbon monoxide, CO, is the other product of this reaction. Write the balanced equation for the reaction, and calculate how much SiO 2 is required to produce 3.00 kg of SiC. Answer \(\ce{SiO2 + 3C \rightarrow SiC + 2CO}\) 4.50 kg SiO 2
23 Απρ 2014 · In 2008, Procter reported the first reductions of unactivated six-membered lactones using SmI 2 –H 2 O. In an impressive example of reagent control over a desired transformation, these reductions were fully chemoselective for δ-lactones over other ring sizes and acyclic esters.
Samarium (II) iodide is a powerful one-electron reducing agent that can be prepared in moderate concentrations (0.1 M) in tetrahydrofuran (THF) by one of several different reactions from samarium metal.
