Which observation most likely indicates that only a chemical change has taken place
salantis [7]

The correct answer as to which observation most likely indicates that only a chemical change has taken place would that the change cannot be reversed.

When it comes to changes in a system, it can either be:

  • physical change
  • chemical change

When a substance undergoes a physical change, the original version of the substance can be recovered. In other words, physical changes can be reversible.

When a substance undergoes a chemical change, the original version cannot be recovered because an entirely new product would have been formed. In other words, chemical changes are irreversible.

Thus, once a change becomes irreversible, such a change is said to be a chemical change.

8. Adding up all of the of all of the individual atoms within one molecule of a compound will determine the
Aleonysh [2.5K]

Answer:

Option A = atomic masses

Explanation:

In compound molecular mass is the sum of the individual atomic masses of the atoms.

For example

Compound NaCl.

atomic weight of sodium = 23 g/mol

atomic weight of chlorine = 35.5 g/mol

Molar mass of NaCl = 23+ 35.5 = 58.5 g/mol

Every atom consist of nucleus or a positive center. The protons and neutrons are present with in the nucleus while electrons are present out side the nucleus. All these three subatomic particles construct an atom. The number of protons or number of electrons are the atomic number of an atom while the number of protons and number of neutrons are the mass number of an atom. A neutral atom have equal number of protons and electrons. In other words we can say that negative and positive charges are equal in magnitude and cancel the each other.
