Photosynthesis is the process in which plants use sunlight to convert water and carbon dioxide into glucose and oxygen. Which of these statements explains why photosynthesis is a chemical change? A New substances are formed with properties that are different from the original substances.

B New substances are formed but their properties are the same as the original substances.

C No new substance is formed but some of the properties change.

D No new substance is formed and the change is easily reversible. Which of the following images shows a chemical change?

Photosynthesis is a chemical change as:

A. New substances are formed with properties that are different from the original substances.

A chemical change happens when one chemical substance is transformed into one or more different substances. A chemical change is different from a physical change, which doesn't rearrange atoms or molecules and produce a completely new substance.

Thus, correct option is A which proves that photosynthesis is a chemical change.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
