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
Is H2O a molecule or compound or both?
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.
Why is water a compound?
Answer. Water is a compound. It contains more than one element:
hydrogen and oxygen atoms are joined together
; as illustrated in the video clip Elements and Compounds, above. … Water is not simply a mixture of hydrogen and oxygen; it contains hydrogen and oxygen atoms linked together in an ordered way.
Is glucose a molecule?
Glucose is
a simple sugar
with the molecular formula C6H12O6. … Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form.
Is H2O a molecule or compound?
For example, water (H2O) is
a compound
consisting of two hydrogen atoms bonded to an oxygen atom. The atoms within a compound can be held together by a variety of interactions, ranging from covalent bonds to electrostatic forces in ionic bonds.
Why h2o is a molecule?
Water is a molecule
because it contains molecular bonds
. Water is also a compound because it is made from more than one kind of element (oxygen and hydrogen). … Oxygen in the atmosphere is a molecule because it contains molecular bonds. It is not a compound because it is made from atoms of only one element – oxygen.
What is both a molecule and compound?
Every combination of atoms is a molecule
. A compound is a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. Hydrogen gas (H
2
) is a molecule, but not a compound because it is made of only one element.
Is milk a compound?
Thus, milk is not a pure substance or a compound that is made up of one type of atom or molecule. But milk is a mixture of fats, proteins, sugar and water which are mixed irrationally. Thus, milk
is a mixture
. So, the given statement ‘milk is a compound’ is false.
Why air is a mixture?
Air is a mixture and not a compound because:
Air does not have a formula like a mixture
, while compounds have a fixed formula. When air is formed by gases, there is no energy change. Properties of air are variable and subjective to time and place.
Is glucose a molecule or an atom?
Glucose is a
monosaccharide
containing six carbon atoms and an aldehyde group, and is therefore an aldohexose. The glucose molecule can exist in an open-chain (acyclic) as well as ring (cyclic) form. Glucose is naturally occurring and is found in fruits and other parts of plants in its free state.
Is oxygen an atom or molecule?
Oxygen is a non-metal element and is found
naturally as a molecule
. Each molecule is made up of two oxygen atoms that are strongly joined together. Oxygen has low melting and boiling points, so it is in a gas state at room temperature.
Is glucose a mixture?
Why glucose is a pure substance? It is a pure substance and
not a mixture as
in a mixture, the components retain their physical and chemical properties. Also, glucose cannot be separated into its constituents by simple physical methods.
Is carbon dioxide is a molecule?
A molecule of carbon dioxide (CO
2
) is
made up of one carbon atom and two oxygen atoms
. Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. … It has a concentration of about 400 ppmv (parts per million by volume) in Earth’s atmosphere.
What is an atom vs molecule?
Atoms are single neutral particles
. Molecules are neutral particles made of two or more atoms bonded together.
