What are the coefficients of this formula Fe plus O 2 equals Fe2 O 3?
It would be: 4Fe + 3O2 2Fe2O3
When do you need to use a roman numeral in the name of a compound?
Roman numerals are typically used in compound names to indicate the oxidation state of an element. This is necessary when the element can have multiple oxidation states and is written as a cation in the compound. For example, iron can exist in the +2 or +3 oxidation state, so the compound name "iron(II) chloride" specifies that it is the +2 oxidation state of iron.
In Iron III sulfate what does the roman numeral tell us?
That the charge of iron is +3 resulting in a formula of Fe2(SO4)3
Overall redox equation fo MnO4 reacting with Fe2 in acid solution give Mn2 and Fe3?
8H+ + MnO4- + 5Fe2+--> 5Fe3+ + Mn2+ + 4H20
What is the oxidation number of the FE2 plus ion?
the answer is 2, my chemistry proffessor told me so. take it or leave it.
Is an oxidation half-reaction A. Fe2 plus Fe3 plus plus e- B. Fe3 plus plus e- Fe2 plus C. Fe(s) Fe(l) D. Fe plus 2e- Fe2 plus?
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.

Why you are usingpotassium ferricyanide indicator externally?
It turns blue in the presence of Fe2+, and can be used to check for possible oxidation/rust
What is name of Fe 2 plus?
Fe^(2+) its name is the iron cation in oxidation state '2' . When combined, with say a sulphate anion it would be named as 'Ferrous sulphate'. NB Ferric sulphate is iron cation in oxidation state '3'. ( Fe2(SO4)3 ). Note the difference in spelling for different oxidation states.
