Tap water is not a pure substance because it is mixed with chemicals that purify it and if it was from the ground it has naturally occurring minerals mixed in it.
Depends but most of the time it is a mixture
mixture
Nickel is a chemical element, and as such, it is a pure substance.
Uranium is a natural chemical element, a pure element.
Carbon is a pure substance with the chemical symbol "C"
Propane (C3H8) is a pure organic compound that can only be broken down by chemical means, thus it is considered a pure substance.
No, it is a mixture of several compounds and cells.
Nickel is a chemical element, and as such, it is a pure substance.
Uranium is a natural chemical element, a pure element.
Neither. C2H2 is a compound (pure substance) so it is not a mixture at all. Hint: mixtures don't have chemical formulas.
Silver is a chemical Element - which means silver is a pure substance.
Copper metal is an element and thus a pure substance.
A mixture can be defined as a material composed of two or more different substances that are not chemically combined. This makes nitrogen a pure substance.
yes benzene is pure substance with chemical formulaC6H6
Carbon is a pure substance with the chemical symbol "C"
Pure. (Its nitrous oxide.)
Propane (C3H8) is a pure organic compound that can only be broken down by chemical means, thus it is considered a pure substance.
CO2 is a pure substance made of two elements, Carbon and Oxygen.
If something is not a mixture then it is a pure substance, either an element or a compound.
