What forms when a soluble substance separate and settles out from solution due to a chemical reaction?
Salt; Precipitation
Are physical and chemical change different?
Physical change does not produce a new substance. Chemical change produces a new substanceIn a chemical change the atoms/molecules are chemically joined together so they are very hard to separate. were as they are easyer to separate in a physical change
Consider a substance that is made of molecules that are stable when dry in the presence of water the molecules separate what type of chemical bond holds the substance together when dry?
An ionic bond.

What does a chemical property give a substance the ability to do?
A chemical property is the properties exhibited by a material in a chemical reaction. This gives a substance the ability to have a chemical identity and is also used in building chemical classifications. The properties can be used in identifying a substance that is unknown or to separate substances. The property also helps in providing information on the application of a substance.
Why can a magnet separate separate iron atoms from the mixture but not from the compound?
Iron atoms are not chemically joined with another substance in a mixture. Chemical reactions are needed to separate them in a compound.
What is a defintite chemical composition?
In mineralogy, definite chemical composition refers to a characteristic that a substance must possess to meet the definition of a mineral. It is the narrow parameter of chemical compositions that a substance must have to be described as a particular mineral separate from other minerals.
