<h3>Changes can occur to the physical properties of a substance, but the chemical composition of the substance remains the same.</h3>
Explanation:
A physical change can not change the chemical makeup of a substance. If it did, it would be considered a chemical change. It can, however, be physically changed.
Answer:
Gallium-72
Explanation:
The elements are identified by the number of protons of the atom, which is its atomic number.
In this case the number of protons 39 (atomic number 39) permit you to identify the element as gallium.
Now, to identify the isotope you tell the name of the element and add the mass number.
The mass number is the sum of the protons and the neutrons
In this case, the number of neutrons is the original 39 plus the 2 added suddenly, i.e. 39 + 2 = 41, so the mass number is 31 + 41 = 72
Therefore, the isotope is gallium - 72.
An indicator is a substance that undergoes a distinct noticeable change when conditions in its solution change. A dye in chemistry <span>is a colored substance that has an affinity to the substrate to which it is being applied.</span>
