The chemical formula of water is H2O. It is also called dihydrogen monoxide.
What is the real name of water?
The story listed a number of alarming safety concerns related to a substance made up of two hydrogen atoms and one oxygen atom (H2O) called dihydrogen monoxide, or water.
Why is H20 called water?
The scientific name for water is H2O. It is called H2O because it has two atoms of hydrogen (H) and one atom of oxygen (O). Water molecules move so fast that they actually break apart from each other and escape into the air as water vapor or steam.
Is H2O a chemical?
H2O is the chemical formula of water. It means that each molecule of water is made up of two hydrogen atoms, indicated by the letter H, and a single oxygen atom, represented by the letter O. Water is chemical substance with no smell, taste or color.
Why is water called water?
The word “water” comes from the Old English word wæter or from the Proto-Germanic watar or German Wasser. All of these words mean “water” or “wet.”
Why is water liquid?
At room temperature (anywhere from zero degree centigrade to 100 degrees centigrade), water is found in a liquid state. This is because of the tiny, weak hydrogen bonds which, in their billions, hold water molecules together for small fractions of a second. Water molecules are constantly on the move.
Which food never expires?
Hard liquor: Exception: cream liqueurs – because of the dairy, heed the label regarding “use by” dates. Honey (raw): Natural sugar, high acidity and low moisture ensures this liquid gold lasts forever (archeologists have even unearthed edible honey in ancient Egyptian tombs).

Which chemical makes up water?
Water is made up of two elements, hydrogen and oxygen. Its chemical formula is H2O. Each molecule of water is made up of two hydrogen atoms bonded to a single oxygen atom . The existence of water is essential for life on Earth.
Is water considered a chemical?
Water as a Compound and Molecule. The chemical formula for water is H 2 O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound. It’s also a molecule, which is any chemical species formed by two or more atoms chemically bonded to each other.
What chemicals is water made of?
Water is a compound composed of the two elements hydrogen and oxygen. This amazing substance can exist near the earth’s surface in all three physical forms: as a liquid, vapor or gas and as a solid.
What are the special chemical properties of water?
The chemical composition of water is H2O – two hydrogen atoms and one oxygen atom. Water has special properties because of the way these atoms bond together to form a water molecule, and the way the molecules interact with each other.
