Calcium is reactive with oxygen, acid, and water. Copper is not reactive with water as well as with acids, whereas magnesium is reactive with acid but reactive with water.
<h3>What is a Chemical Reaction?</h3>
One or more chemicals (the reactants) are changed into one or more other compounds during a chemical reaction (the products).Substances are made up of chemical components or chemical elements.
Each calcium atom donates a pair of electrons to an oxygen atom during the interaction between calcium and oxygen to create calcium oxide.
When calcium reacts with hydrochloric acid, it releases bubbles of hydrogen gas, and when large chunks of calcium react with hydrochloric acid, it releases hydrogen gas. Calcium in reaction with water produces calcium hydroxide and hydrogen gas
When magnesium and oxygen interact, they produce light that is so strong that it temporarily impairs your vision. Magnesium burns so brilliantly because it produces a lot of heat while doing so.
Magnesium reacts with hot water or water vapor to produce hydrogen gas and magnesium hydroxide.
Acid does not react with copper. Metals such as lead, copper, silver, and gold do not react with water at all.
