Formula units
No, anything with atoms of a single element is a pure substance. For example (DO NOT TRY IT), but JUST picture a glass filled with mercury (Hg). if there are only Hg molecules, then it is a pure substance.
Tuff is a mixture that varies in composition. Because of this it cannot be regarded as a single substance and so does not have a chemical formula.
Acid is not any single substance but a class of substances with a wide variety of chemical formulae.
Elemental copper does not have molecules. Instead it has a "formula unit", which is a single atom.
The formula for water molecule is H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
Anitoxidants are not a single substance but a whole set of substances. As such, there is no single chemical formula.
No, anything with atoms of a single element is a pure substance. For example (DO NOT TRY IT), but JUST picture a glass filled with mercury (Hg). if there are only Hg molecules, then it is a pure substance.
C21H30O2 is the chemical formula for Tetrahydrocannabinol, the main psychoactive substance found in the Cannabis plant. C21H30O2 is just a single molecule composed of 53 atoms.
The Type of substance of a molecule would be an element.
No, it is a compound of two molecules of hydrogene and 1 of oxygene. Thus giving you H2O
Tuff is a mixture that varies in composition. Because of this it cannot be regarded as a single substance and so does not have a chemical formula.
Acid is not any single substance but a class of substances with a wide variety of chemical formulae.
SO is a diatomic molecule. Si is a single atom. Io is not any chemical substance but one of the moons of Jupiter. IO however would be a diatomic molecule. Hint: if there is only one capitalized letter in the formula and no subscripted number, it is just a single atom.
Elemental copper does not have molecules. Instead it has a "formula unit", which is a single atom.
The formula for water molecule is H2O: one molecule of water has two hydrogen atoms covalently bonded to a single oxygen atom.
Formula regards the composition of a substance. In Chemistry molecular formula is derived by the composing elements and their atomic quantities. For example the chemical formula of water (H2O) is two hydrogen and single oxygen.
Yes, a compound is a single substance.
