Answer:
Because the number of neutrons is different, the mass number is different. Isotopes are written in two different ways. They can be written using their symbol with the mass number (to the upper left) and atomic number (to the lower left) or the isotope name is written with a dash and the mass number

Answer:
c) bromthymol blue
Explanation:
An acidic solution has a pH value less than 7, while the pH is 7 for a neutral solution and grater than 7 for a basic solution.
Bromothymol blue is a pH indicator which is yellow in color when placed in an acid (pH under 7), the color is green in a neutral solution (pH of 7) and blue in an basic solution (pH over 7).
If bromthymol blue is added to a solution with an initial pH of 5.5 (acidic), the color would be yellow and as the pH changes to 8 (basic), the color changes to blue.
The reaction of potassium iodide with silver nitrate results in the formation of silver iodide as a precipitate.
<h3>What is a precipitate?</h3>
A precipitate is given as the solid deposition in the solution. It is formed as the product in the chemical reaction with the insolubility in the solution.
The reaction of KI with silver nitrate results in the formation of soluble potassium nitrate and insoluble silver iodide, which forms as the precipitate.
Thus, the reaction of potassium iodide with silver nitrate results in the formation of silver iodide as a precipitate.
