Is hydrogen gas a pure substance or a mixture?
Hydrogen gas is a pure substance because it consists of only one type of atom, which is hydrogen. It is not a mixture because it does not contain different substances mixed together.
Differentiate a substance from a mixture?
A mixture contain two or more substances (compounds).
Is a diamond a pure substance or a mixture?
Simple answer: it is a pure substance Non-Simple answer: Diamonds contain impurities in their lattice structure that are other elements, so technically it is slightly a mixture, but only if you get really picky about it.
Is gold a mixture?
No, gold is an element, not a mixture. It is a pure substance composed of only gold atoms.
Whats the difference between homogenous mixture and heterogeneous mixture?
A homogenous mixture has uniform composition throughout, where the components are evenly distributed and not distinguishable by the naked eye, like salt dissolved in water. A heterogeneous mixture has non-uniform composition, where the components are not evenly distributed and can be visually distinguished, like a mixture of oil and water.
What is a mixture that contains only one substance?
A mixture that contains only one substance is called a homogenous mixture, such as salt dissolved in water. In this case, even though it appears to be a mixture, it is still only one substance present.
What is the difference in a pure substance and a mixture?
A pure substance is made out of only one kind of element (for example, gold is a pure substance). A mixture is made out of two or more different substances and is only combined by physical means. A pure substance cannot be broken down into a simpler substance. A mixture can be separated into its component parts.
Is a diamond mixture or a pure substance?

A mixture contain two or more substances (compounds).
Is the particles of a pure substance different?
No, the particles of a pure substance are all the same kind. In a pure substance, such as an element or a compound, the particles are identical in their chemical makeup. This is what distinguishes a pure substance from a mixture, where different substances can be present in varying proportions.
Is iron a heterogeneous mixture?
No, Iron is a homogeneous mixture as long as the iron is pure
What is the difference between a pure substance and a homogenous mixture?
A pure substance is a substance that has only that substance in it. One kind of molecule or atom. A homogenous mixture can have different molecules and/or atoms in it, but they have to be in the same physical state. Water mixed with honey would be a homogenous mixture, because they are both liquids. Water mixed with sand would be heterogeneous.
Is helium gas a mixture?
No. Helium is an element, which makes it a pure substance.
