Answer:
The oxidation number of iron changes from 2+ to 0.
10 electrons are transferred in the reaction.
Explanation:
Step 1: Write the balanced redox reaction
5 Fe²⁺ + 2 Mn²⁺ + 8 H₂O ⇒ 2 MnO₄⁻ + 5 Fe + 16 H⁺
Step 2: identify both half-reactions
Reduction: 5 Fe²⁺ + 10 e⁻ ⇒ 5 Fe
Oxidation: 2 Mn²⁺ + 8 H₂O ⇒ 2 MnO₄⁻ + 16 H⁺ + 10 e⁻
Step 3: Identify the oxidation state change of iron
Iron changes from Fe²⁺ to Fe, that is, the oxidation number changes from 2+ to 0.
Step 4: Determine how many electrons are transferred in the reaction?
According to both balanced half-reactions, 10 electrons are transferred in the reaction.
25 * 10^-3 L * 0.1 Mole/L = 25*10^-4 Moles
Hope it helps.
The electron configuration of Lithium is 1s2 2s1
Answer:
The enzyme's active site must be the mold shape of the substrate.
Explanation:
An enzyme and a substrate bind together in order to work. If the shapes of the 2 are different, they will not be able to bond together. If the shapes of the 2 fit glove-in-hand, then they will be able to bond together.
