<span>*Acids taste sour. The lemon, vinegar, tamarind contain acids; that's why they are sour.
*The acids change the color of certain substances called indicators. The indicators have the property of changing color as the character acid or basic solutions. The litmus and phenolphthalein are indicators of acids and bases. The solution of phenolphthalein is colorless red in the presence of an acid. Already the blue litmus paper turns red.
*The acids react with bases to form salts and water. This reaction is called neutralization reaction.</span>

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 answer for the equation given is 1.743488.
<h3>Equation :</h3>
10,000/ 5,735.63 = 1.743488.
<h3>How are units labeled?</h3>
Use standardized unit abbreviations. For clarity, place units of before nonstandard units, such as (a) (units of a). When separating the components of a compound unit, use short spaces rather than hyphens, dots, or other symbols. For numbers on figure axes, use superscripts, multiplication signs, and powers of 10.
<h3>What is label in math means?</h3>
A graph labelling is the process of assigning labels, which are typically represented by integers, to the edges and/or vertices of a graph in the field of mathematics known as graph theory.
