Answer:
1 = oxidation
2 = reduction
Explanation:
Oxidation:
Oxidation involve the removal of electrons and oxidation state of atom of an element is increased.
2I- ----> I₂+ 2e⁻
Reduction:
Reduction involve the gain of electron and oxidation number is decreased.
F + e⁻ ----> F⁻
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.
Answer:
There are 0.1387 moles of oxygen atoms.
Explanation:
First we <u>calculate how many moles of ammonium phosphate there are</u>:
- There are 3 nitrogen moles per (NH₄)₃PO₄ mole.
- There are 0.104 nitrogen moles
- Thus there are (0.104 mol N * ) 0.0347 moles of (NH₄)₃PO₄.
Finally we calculate<u> how many moles of oxygen atoms are there in 0.312 moles of (NH₄)₃PO₄</u>:
- There are 4 oxygen moles per (NH₄)₃PO₄ mole.
- There are 0.0347 moles of (NH₄)₃PO₄.
Thus there are (0.0347 mol (NH₄)₃PO₄ * ) 0.1387 moles of O.
