Problem #3: Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction: 2Al + 3Cl 2---> 2AlCl 3. How many grams of aluminum chloride could be produced from 34.0 g of aluminum and 39.0 g of chlorine gas? Solution: 1) Determine the limiting reagent: Al ⇒ 34.0 g / 26.98 g/mol = 1.2602 mol
This quiz helps you practice stoichiometry and limiting reagents problems and calculating the percent yield of chemical reactions.
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.
Balance the following equations of redox reactions: Assign oxidation numbers to all elements in the reaction; Separate the redox reaction into two half reactions; Balance the atoms in each half reaction; Add the two half-reactions together and cancel out common terms
Samarium (II) iodide is an inorganic compound with the formula SmI 2. When employed as a solution for organic synthesis, it is known as Kagan 's reagent. SmI 2 is a green solid and forms a dark blue solution in THF. [1] . It is a strong one-electron reducing agent that is used in organic synthesis.
