Answer:
5Fe⁺² + MnO₄⁻ + 8H⁺ => 5Fe⁺³ + Mn⁺² + 4H₂O
Explanation:
Fe⁺² + MnO₄⁻ + H⁺ => Mn⁺² + Fe⁺³ + H₂O
5(Fe⁺² => Fe⁺³ + 1e⁻) => 5Fe⁺² => 5Fe⁺³ + 5e⁻
<u>MnO₄⁻ + 5e⁻ => Mn⁺² => MnO₄⁻ + 8H⁺ + 5e⁻ => Mn⁺² + 4H₂O</u>
=> 5Fe⁺² + MnO₄⁻ + 8H⁺ => 5Fe⁺³ + Mn⁺² + 4H₂O
The series of reactions is:
4 NH3 + 5 O2 → 4 NO + 6 H2O <span>
6 NO + P4 → P4O6 + 3 N2
P4O6 + 6 H2O → 4 H3PO3
4 H3PO3 → PH3 + 3 H3PO4 </span>
<span>
We multiply the first equation by a number 3 and all the
other equations by number 2, so that we get:
12 NH3 + 15 O2 → 12 NO + 18 H2O
12 NO + 2 P4 → 2 P4O6 + 6 N2
2 P4O6 + 12 H2O → 8 H3PO3
8 H3PO3 → 2 PH3 + 6 H3PO4
Then the overall reaction is:
12 NH3 + ... → 2 PH3 + ...
</span>
<span>So calculating for PH3:
<span>(1.10 g NH3) / (17.0306 g NH3/mol) x (2/12) x (33.9976 g
PH3/mol) = 0.366 g PH3</span></span>
