How can you tell water is a compound molecule?
A compound forms whenever two or more atoms form chemical bonds with each other. The chemical formula for water is H2O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.
Why do we say water molecule?
If it were made up of more than one kind of atom, it would be a compound. 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 can a water molecule be described as?
Water is a chemical compound and polar molecule, which is liquid at standard temperature and pressure. It has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. Water is found almost everywhere on earth and is required by all known life.
What is it called when a molecule like water?
The property of cohesion describes the ability of water molecules to be attracted to other water molecules, which allows water to be a “sticky” liquid. The attraction between individual water molecules creates a bond known as a hydrogen bond.
How do you know if something is a molecule or compound?
A molecule is formed when two or more atoms of an element chemically join together. And a compound is a type of molecule, in which the types of atoms forming the molecule are different from each other.
Why is H2O not a compound?
Hydrogen gas (H2) is a molecule, but not a compound because it is made of only one element. Water (H2O) can be called a molecule or a compound because it is made of hydrogen (H) and oxygen (O) atoms. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds.
Is water a compound?

How is a water molecule like a magnet?
Explanation: Water molecules are basically, H2O molecules, which have bent shapes. So, the entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each O−H bonds, and thus, the water molecules are polar in nature and act like “little magnets”.
Why is water considered a compound class 9?
A compound is a chemical substance of many identical molecules composed of atoms from more than one element held together by chemical bonds. Water with the chemical formula of H2O is considered a compound because it comprises two elements – hydrogen and oxygen, which are combined in the ratio of 1:8.
Why water is considered a compound mention two points?
Water is considered as compound because: (i) Water is composed of two elements:hydrogen and oxygen. (ii) The ratio of hydrogen and oxygen by mass in any sample of pure water is the same. (iii) The properties of water are different from its constituent elements: hydrogen and oxygen.
What is special about water as a compound?
Well, a compound forms whenever two or more atoms form chemical bonds with each other. Each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Knowing specifically and accurately that water is for sure a compound makes it special and very interesting.
Why is water a molecule and a compound?
Water is a molecule because it is made from atoms that have been chemically combined. It is also a compound because the atoms that make water are not all the same – some are oxygen and some are hydrogen. Oxygen in the atmosphere is a molecule because it is made from two atoms of oxygen.
Which compound is more soluble in water?
The compound that is more soluble in water is acetone rather than 2-pentanone. Acetone or propanone cannot hydrogen bond with themselves but can hydrogen bond with water molecules. One of the slightly positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on the oxygen atom of propanone.
Is water an element or a compound or a mixture?
Water is a compound made of two atoms of hydrogen and one atom of oxygen. The hydrogen atoms are bonded to the oxygen atom by the sharing of electrons, called a covalent bond.
