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.

How do you balance fe2o3 plus hno3 plus fe no3 3 plus H2O?

Step 1: Count elements on both sides Left: Fe = 2, O = 3 (from Fe₂O₃) + 3 (from 3 HNO₃) = ?, need to fix. Right: Fe = 1 (in Fe(NO₃)₃) → we’ll need 2 of those. Step 2: Balance Fe Fe2O3+HNO3→2Fe(NO3)3+H2OFe_2O_3 + HNO_3 \rightarrow 2Fe(NO_3)_3 + H_2OFe2​O3​+HNO3​→2Fe(NO3​)3​+H2​O Now Fe is balanced (2 each side). Step 3: Balance NO₃ groups and H Each Fe(NO₃)₃ has 3 nitrate groups, and there are 2 Fe(NO₃)₃ → total 6 nitrate ions. So, we need 6 HNO₃ on the left. Fe2O3+6HNO3→2Fe(NO3)3+3H2OFe_2O_3 + 6HNO_3 \rightarrow 2Fe(NO_3)_3 + 3H_2OFe2​O3​+6HNO3​→2Fe(NO3​)3​+3H2​O ✅ Balanced Equation: Fe2O3+6HNO3→2Fe(NO3)3+3H2O\boxed{Fe_2O_3 + 6HNO_3 \rightarrow 2Fe(NO_3)_3 + 3H_2O}Fe2​O3​+6HNO3​→2Fe(NO3​)3​+3H2​O​

What is the formula for Fe plus 3?

This is the ion Fe(3+).


When the equation fe plus cl2?

When iron (Fe) reacts with chlorine gas (Cl2), they form iron (III) chloride (FeCl3) according to the equation: 2 Fe + 3 Cl2 → 2 FeCl3. This reaction is a redox reaction where iron is oxidized and chlorine is reduced.

How do you find the number of ions in 2 mol of Fe3 plus?

Use Avogadro's number. 2 mole Fe(3+) ( 6.022 X 10^23/1 mole Fe(3+) ) = 1.20 X 10^24 ions of Fe(3+)


What species is reduced in the reaction Fe plus AgNO3 Fe(NO3)3 plus Ag?

Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
