Answer
MnO₄ + 2H⁺ +3NO₂⁻ →3NO₃⁻ + Mn²⁺ +H₂O
Explanation
This is a redox reaction (oxidation-reduction reaction) which involves the transfer of electrons between two species. i.e
Mn + 6e⁻→Mn²⁺ (reduction)
3N³⁺- 6e⁻→3Mn⁵⁺(oxidation)
The answers are :
1 - F
2- T
The frequencies expressed in inverse seconds are 5 s⁻¹ and 1 s⁻¹.
<h3>
What is frequency?</h3>
Frequency is the number of complete cycles in a second made by a wave.
F = 1/T
F = n/t
<h3>When n = 5</h3>
F = 5/s = 5 s⁻¹ = 5Hz
<h3>When n = 1</h3>
F = 1/s = 1 s⁻¹ = 1Hz
