Pure sodium reacts very violently when dropped into water; it produces an exothermic reaction that causes the sodium to bounce and skip across the surface of the water -- or if suddenly immersed, to explode.
Pure magnesium, when it is burning, also causes a violent reaction in water.
Naturally, performing either of these should not be attempted at home, especially not by anyone who isn't a chemist by trade!
When something reacts, that is a chemical reaction. Chemical change.
Chemical
Strontium reacts with water producing strontium hydroxide and hydrogen gas. This is a chemical change.
It is a chemical change, because the borax reacts to the heated water.
If something reacts with oxygen that is a description of a chemical property.

If something reacts with water to form a gas, it's demonstrating a chemical property. The reaction has caused it to become something new, which is a telltale sign of a chemical property.
Water is a compound because 2 elements are chemically bonded together within each molecule of water there are 2 hydrogen atoms and 1 oxygen atom. Because this compound is the same, same properties, no matter where it comes from or how you get it, it is said to be a chemical. Its chemical properties such as how it reacts to other substances are always the same for pure water.
