Its called a compound
The answer is "a mixture".
a molecule
A nonchemical combination of two or more substances in variable proportions is a mixture.
a pure substance made of more than one element is a compound.
something
Gold can only be made out of gold, and nothing more. If gold were to be made out of something else, it wouldn't be gold anymore.
Compound
Well definite is broad and multiple is more exact that's about what I can think of
COMPOUNDS.
Two or more chemcal elements combined in constant proportions.
By studying self proportions
A substance made from two or more elements in definite proportions. eg NaCl
A nonchemical combination of two or more substances in variable proportions is a mixture.
a pure substance made of more than one element is a compound.
An element is a substance made up of one particular type of atom. A mixture is made up of two or more substances in varying proportions.
The standard deviation would generally decrease because the large the sample size is, the more we know about the population, so we can be more exact in our measurements.
because we have more technology
A compound is a substance of two or more elements bounded together in definite atomical proportions
A mixture is a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each other.
