What Colour is water?
The water is in fact not colorless; even pure water is not colorless, but
has a slight blue tint to it
, best seen when looking through a long column of water. The blueness in water is not caused by the scattering of light, which is responsible for the sky being blue.

Is a human’s blood blue?
Human blood is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen
in their blood, hemocyanin, is actually blue
.
Can oxygen burn?
Oxygen itself does not burn
but a fire needs oxygen to start and to keep burning. When more oxygen is in the air, the fire will burn hotter and faster.
What is the odor of oxygen?
Oxygen is a
colourless, odourless, tasteless gas
essential to living organisms, being taken up by animals, which convert it to carbon dioxide; plants, in turn, utilize carbon dioxide as a source of carbon and return the oxygen to the atmosphere.

Are atoms colorless?
atoms (as opposed to molecules) do not have colors –
they are clear except under special conditions
.. you could not see the color of one atom or molecule – not because it is too small – but because the color of one atom would be too faint.
Is Diamond an element?
Diamond is
composed of the single element carbon
, and it is the arrangement of the C atoms in the lattice that give diamond its amazing properties. Compare the structure of diamond and graphite, both composed of just carbon.
Is milk an element?
Milk is
not an element
that is listed on the periodic table. Milk is not a single compound, but a mixture of compounds.
Is chalk an element?
Chalk is not an element
and thus it may be a compound or mixture depending upon the composition. as chalk is Calcium carbonate. When dust particles are present then it may be called as a mixture.
