What is water made up of? (2023)

What is water made up of?

A water molecule has three atoms: two hydrogen (H) atoms and one oxygen (O) atom. That's why water is sometimes referred to as H2O. A single drop of water contains billions of water molecules.

What is water small answer?

Water is the liquid that makes life on Earth possible. As water cycles from the air to the land to the sea and back again, water shapes our planet — and nearly every aspect of our lives. All Living Things Need Water.

Is water a compound or a mixture?

Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.

What is water answer for kids?

Water is made of tiny units called molecules, which are combinations of even smaller units called atoms. A molecule of water is made of two hydrogen atoms and one oxygen atom. The scientific formula for water is H₂O. Water can be found in three physical states: liquid, solid (ice), or gas (steam or vapor).

Examples of Heterogeneous mixtures – air, oil, water, etc.

What are the 5 purposes of water?

What controls the water in the body?

The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary. Water is lost through the skin through evaporation from the skin surface without overt sweating and from air expelled from the lungs.

How do you make water?

In English, the equation says: To produce two molecules of water (H2O), two molecules of diatomic hydrogen (H2) must be combined with one molecule of diatomic oxygen (O2).

How was water first created?

Water was first created in deep space, after hydrogen and oxygen first formed. All hydrogen atoms were created about 380,000 years after the big bang. Oxygen was created much later in the nuclear furnaces of stars, towards the end of their life cycles. Stellar lives begin by converting hydrogen into helium.

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."

Water is a pure substance because it contains only one type of molecule. Pure water is made by the chemical combination of hydrogen and oxygen. One oxygen is bonded to two hydrogen. And it always has fixed composition.

How can water be pure answer?

Is water a base or an acid?

Pure water is neither acidic or basic; it is neutral. So how does something become acidic or basic? That happens when the hydroniums and the hydroxyls are out of balance. If there are more positively charged hydroniums than negatively charged hydroxyls, then the substance is acidic.

Is rain water pure?

Germs and other contaminants are found in rainwater.

While useful for many things, rainwater is not as pure as you might think, so you cannot assume it is safe to drink.
