There are 66 neutrons in a single atom of indium-115. The atomic number of indium-115 is 49, meaning there are 49 protons. Then the atomic mass is 115, so 115-49 = 66.
Nope, its A i just took the test
<span>Two neutral hydrogen atoms share electrons in a covalent bond.

The negative log function that determines the acidity or alkalinity by hydronium ion concentration is called pH.
The substance having high will have:
Option B. A low and a high
This characteristic can be explained as:
- The concentrations of and are inversely dependent on each other so when the concentration of raises then the concentration of drops and vice versa.
- The pH of a solution or substance is calculated with the help of:
From the formula, it can be deduced that when the concentration of is high then the pH has a low value and it means that the solution is acidic.
- pH can also be written as:
From this formula we can that when the value of pH is less then the value of pOH will be increased and vice versa.
Therefore, when pOH is in high concentration then is low.
