They help bring about chemical reactions. This is because enzymes act as catalysts, lowering the activation energy required for a chemical reaction to initiate. It is in this way that they bring about chemical reactions.
If the concentration of a dilute solution of nitric acid is 0. 0001 M. The pH of the solution is 4.
<h3>What is pH ? </h3>
pH is used to measure whether the substance is acidic, basic or neutral and the range is 0 - 14.
<h3>How to find the pH of the solution ?</h3>
To calculate the pH hydrogen ion it is expressed as:
pH = - log [H⁺]
So, concentration of hydrogen ion in HNO₃ is 0.0001 M.
pH = - log [0.0001]
= 
= - log (10)⁻⁴
= -4 × - log (10)
= - 4 × (-1)
= 4
Thus from the above conclusion we can say that The pH of the solution is 4.

Answer:
Nonmetals are located on the upper right side of the Periodic table (see above image). Exception: Hydrogen is a nonmetal which is located on the left top corner of the Periodic table. Well, you have got the answer of “Where are Nonmetals located on the Periodic Table?”
