No. The clay used for bricks is not a pure substance.
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
A mineral
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.
Hemitite has the properties of naturally occuring, inorganic, and crystal structure. Brick is man-made, and the chemical composition varies.
minerals in microphones are solid homogeneous inorganic substances occurring in nature with a definite chemical composition.
Minerals have a definite chemical composition, are solid, are inorganic, are naturally occurring, and have a crystalline structure.
Atom
Yes
yes it can
A definite chemical composition
Colon is an organ not a compound with definite composition.
Yes
This law hasn't a chemical equation !
A definite chemical composition
it means a naturally-occaring, inorganic solid that has a crystal structure and a definite chemical composition
Definite chemical composition is when a mineral is made of the same material throughout. Basically when a mineral is only made of one material all the way through, not part iron in one part and then gold in the rest.
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
