yes it can
Mixtures can be broken down by physical means.
You can break down a mixture by physical means
No.
a substanceis pure it can be broken down using physical processes while a mixture can be separated using physical processes and it is a combination of substances.
An element is a pure substance that can not be broken down by chemical means into other substances. A compound is a pure substance that cannot be broken down by physical means but it can be broken down by chemical means.
Iron is a element, not a compound. Elements can only be broken down to electrons, protons, and neutrons. Elements, like Iron, can brake down to subatomic particles when exposed to extreme pressure, like in a particle accelerator, or when exposed to extreme heat, like in a fusion reactor. So yes, Iron can be broken down, but only with very large amounts of Energy.
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
mixture is separted by physic changes and compound is broken down by chemical changes
A pure substance that cannot be broken down into simpler substances by physical or chemical means is an element. This is because Elements can't be broken down chemically into other substances because there is nothing to break them down into.
All substances can be broken into any other substances (or elements) by chemical or physical methods.
Nitrous oxide is a mixture of two or more substances. Therefore, it is a heterogeneous substance. An example of a colloid mixture would be blood.
