Cellulose and starch would be the indicator that the unknown substance is a plant.
Answer:
Explanation:
Oxidation:
1) Oxidation involve the removal of electrons.
2) Oxidation occur when oxidation state of atom of an element is increased.
Reduction:
1) Reduction involve the gain of electron.
2) Reduction is occur when number of electrons increased in an atom and oxidation state decreased.
Consider the following reactions.
4KI + 2CuCl₂ → 2CuI + I₂ + 4KCl
the oxidation state of copper is changed from +2 to +1 so copper get reduced.
CO + H₂O → CO₂ + H₂
the oxidation state of carbon is +2 on reactant side and on product side it becomes +4 so carbon get oxidized.
Na₂CO₃ + H₃PO₄ → Na₂HPO₄ + CO₂ + H₂O
The oxidation state of carbon on reactant side is +4. while on product side is also +4 so it neither oxidized nor reduced.
H₂S + 2NaOH → Na₂S + 2H₂O
The oxidation sate of sulfur is -2 on reactant side and in product side it is also -2 so it neither oxidized nor reduced.
The most comprehensive definition is 2nd definition which involves the increase or decrease in oxidation state.
Oxidation occurs at the anode, so your answer is (2) loss of electrons
I'm not sure if what this question is asking but ill be assuming that the average molecular mass is required. An assuming that the abundance of each isotope is 50% the average molecular mass is 69.82 amu.
Answer:
MgSo4 is the right answer
