<u>Answer:</u> The ratio of number of hydroxide ions to iodide ions is 2 : 1.
<u>Explanation:</u>
The chemical equation for the oxidation of iodide ion is oxidized to hypoiodite ion by permanganate follows:
According to mole concept:
1 mole of a substance contains number of particles
Moles of iodide ions = 1 mole
Number of iodide ions =
Moles of hydroxide ions = 2 mole
Number of hydroxide ions =
Taking the ratio of number of hydroxide ions and number of iodide ions are as follows:
Hence, the ratio of number of hydroxide ions to iodide ions is 2 : 1.

Answer:
The atoms in a gas move at high speeds
Answer:
2H⁺ + NO₃⁻ + 1e⁻ → NO₂ + H₂O
Explanation:
NO₃⁻ → NO₂
In left side, Nitrogen acts with +5 by oxidation number
In right side, the oxidation number is +4
This is a reduction reaction, because the oxidation number has decreased. So the N has gained electrons.
NO₃⁻ + 1e⁻ → NO₂
In acidic medium, we have to add water, where there are less oxygens to ballance the amount. We have 2 O in left side, and 3 O in right side, so we have to add 1 H₂O on left side.
NO₃⁻ + 1e⁻ → NO₂ + H₂O
Now that oxygens are ballanced, we have to ballance the hydrogens by adding protons in the opposite side
2H⁺ + NO₃⁻ + 1e⁻ → NO₂ + H₂O
