A substance can be a mixture or solution, rather than a compound. These do not require that the separate substances combine chemically. An element is a substance that has only one type of atom.
A synthesis reaction forms a new compound from two other separate substances. The new compound is chemically distinct from the substances it was formed from.
Salt; Precipitation
Yes, but not physically, only chemically. Part of the definition of a compound, as opposed to a mixture or solution, is that compounds can only be separated back into their respective elements through a CHEMICAL process.
No, black pepper is not a pure substance. Instead, black pepper is what we call a mixture substance. However, salt is a pure substance.
Only a chemical reaction can separate a compound into its parts.☻
There are 2 very different ways to separate a compound. You can separate a compound by doing a single or double replacement reaction or by melting the compounds.
It's called Decomposition. For example, 2KClO3 --> 2KCl + 3O2
Decomposition reaction
compound as it decomposed into two separate things.
chemical reaction
Iron atoms are not chemically joined with another substance in a mixture. Chemical reactions are needed to separate them in a compound.

When two substances combine to form a new substance, it is said that a chemical reaction has occurred. This reaction is a combination reaction, also known as synthesis. The new substance formed may or may not possess the properties of the constituent substances.When the separate substances are elements, a chemical reaction is one that creates chemical bonds, the combined substance being a compound.

A decomposition reaction takes one reactant and makes multiple products. AB -> A + B
