Answer:

The term matter refers to anything that occupies space and has mass—in other words, the “stuff” that the universe is made of. All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.

The illustration on the left represents a mixture of H2 (light blue) molecules and O2 (red) molecules. If these were to react to
kvasek [131]

Answer:

6 molecules of H2O are the maximum number.

Explanation:

From the drawing it can be seen that there are 6 H2 molecules and 3 O2 molecules reacting, which can be represented by the following chemical equation

6 H2 + 3 O2 ⇒ H2O

This equation is not balanced, so we proceed to balance it, being as follows:

6 H2 + 3 O2 ⇒ 6H2O

With which it can be determined that a maximum of 6 H2O molecules can be formed.
