Answer:
The answer is below
Explanation:
They are isotopes. Isotopes are molecules that have the same atomic number but have different atomic mass because the number of neutrons is different.
Iodine has an atomic mass of 126 g and its atomic number is 53.
# of neutrons = 126 - 53 = 73
Its isotope has an atomic mass of 128 g its atomic number is also 53, but the number of neutrons is different.
# neutrons = 128 -53 = 75
Answer:
Phenolphthalein is a chemical compound with the formula C20H14O4 and is often written as "HIn" or "phph" in shorthand notation. Phenolphthalein is often used as an indicator in acid–base titrations. For this application, it turns colorless in acidic solutions and pink in basic solutions.

The movement of the blades represents wind energy.
The visible light that allows people to see where they are going describes light energy.
<h3 /><h3>What is a wind energy?</h3>
A wind energy is the energy that results from the blowing the wind.
The blowing of the wind causes the windmill blade to rotate converting kinetic energy into mechanical energy of the moving blades.
<h3>What is light energy?</h3>
Light energy is the energy that allows light to be visible to human eyes.
Thus, we can conclude that the movement of the blades represents wind energy.
The visible light that allows people to see where they are going describes light energy.

Salt Water is classified as a:
4) mixture because the proportion of its components can vary.
Salt water is composed of salt and water. Regardless of the amount of salt or water put together, these two still form salt water.
