A reduction reaction is frequently used to obtain pure metals.
Zero. The oxidation of one compound must be matched by the reduction of another.
it forms iron oxide, and it can/should form rust
Yes this should be correct. Fluorine needs one electron to complete the shell, which will give fluoride a -1 charge.
+1 . The oxidation number of an ion is always equal to the charge. The silver ion is Ag+ in compounds such as silver chloride. There is also an Ag3+ in compounds such as AgO, which contains Ag+ and Ag3+ in 1:1 proportions, so contains silver with +1 and +3 oxidation numbers and is called silver(I,III) oxide
0 in the elemental form +2 in its compounds
The oxidation number for Cl in ClO is +1. This is because the oxidation number of oxygen in most compounds is -2, and the sum of the oxidation numbers in ClO must equal the charge of the ion, which is -1.
A redox half reaction is a reduction or an oxidation reaction. He half reaction does not occur by itself it much be coupled so that he electron released for another to be accepted.
Chlorine has 7 valence electrons and requires one more electron to complete the octet. Hence it has an oxidation number of -1. But, it should be noted that chlorine show positive oxidation numbers (up to +7) also in its compounds
No, you should use the amount of extract that is called for in the recipe.
The opposite compound in the carbon cycle is carbon dioxide. (We breathe in air, remove the oxygen, breathe out carbon dioxide.) The opposites of reactions that use oxygen (aerobic) are those that don't (anaerobic).
The conclusion of your essay should restate the thesis statement and summarize the key points in the body of your paper. Your essay and can include a short discussion of further research on the topic of oxidation.
-1 oxidation state. This ion should be called Kallide
