you can do a silica aided reaction.... it's Cr becomes less of a biohazard then.
You can only make any ketone from any secondary alcohol by using PCC, Jones reagent, or NaCr2O4 in acid as a reagent.
After using a reagent, you should securely close the container to prevent spills or contamination. Store the reagent according to the manufacturer's instructions, making sure to label it with the date it was opened and any other relevant information. Dispose of any waste following proper laboratory protocols.
Bromine gas (or bromine in any other state of matter except plasma) is a chemical element, and the oxidation number of any element in its elemental state is zero by definition.
Since manganese is a metallic element, its oxidation number in metallic form is 0, as for any other element.
The reagent blank should contain everything that the sample contains, except one variable. That variable could be the active ingredient, the enzyme, the substrate, or some other ingredient that is essential to the reaction. If water is added to all the other tubes, it must also be added to the reagent blank.
The oxidation number of S in S8 is 0. Each sulfur atom in S8 has an oxidation number of 0 because it is in its elemental form and not bonded to any other element.
The oxidation state of a lone element is 0. Lone elements are in their elemental form and do not have any other atoms to share or transfer electrons with, resulting in an oxidation state of 0.
The oxidation of any element, by itself, is zero.
The oxidation number of an atom states how it shares its valence electrons with other elements (or ions or compounds). A neutral atom always has its oxidation number 0: it does not share any electrons. A cation has a positive oxidation number and that of anion is negative because they donate and attract electrons respectively.
No neptune does not have any other kind of liquids on it. -reanni Jones
The oxidation number of magnesium is +2. Any other for this element would be energetically unfavorable and unstable.
In most reactions there are two types of reactant. One of them is completely consumed and the other is only partially consumed. The reactant that is only partially consumed is the excess reactant.
