When two substances combine but no new substances are formed, they undergo a physical change rather than a chemical change. This can occur through processes like mixing, dissolving, or blending, where the individual properties of each substance remain intact. An example is mixing salt and water; the salt dissolves, but both the salt and water retain their original properties. Such mixtures can usually be separated by physical means, such as evaporation or filtration.

What is formed when two substances combine and form a new substances combine and form a new substance which cannot return to their original form?
a chemical reaction
A synthesis reaction is a reaction between two compounds in which?
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.
When two diffrent substances combine by making chemical bonds what is the result?
When two different substances combine by making chemical bonds, the result is another chemical compound.
What is the chemical property that describes the ability of two or more substances to combine to form new substance?
This property is called reactivity.
What is created when chemicals reactions jion atoms togethter?
If atoms of same element combine, we say that element is existing in its real state (or simply a molecule of that element is formed). If two atoms of different elements combine, a compound is formed.

What are formed when two or more elements chemically combine?
Compound is formed by the chemical combination of two or more substances.
A synthesis reaction is a reaction between two compounds in which?
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.
When two substances combine chemically the properties of the products of what?
When two substances combine chemically, the properties of the products are different from those of the starting materials. This is because new chemical bonds are formed, leading to a different arrangement of atoms and different chemical properties.
What is formed when two or more substances combine?
Its a chemical change, and the simplest is when two atoms combine to from a compound. When there is a single oxygen atom, it is called ozone, then two combine in an ionic bond, they are an oxygen molecule.
What is the ability of two or more substances to combine and form one or more new substances?
Reactivity
When two elements combine to form a new substance is the new substance an element Why and why not?
No, the new substance formed when two elements combine is not an element. Elements are substances made of only one type of atom, while compounds are made of two or more different types of atoms chemically combined. The new substance formed from the combination of two elements is a compound, not an element.
What kind of reaction is it when two substances combine to form a new reaction?
A synthesis reaction
Two or more substances that are together but do combine to form a new pure substance?
mixture
What is it calledwhen two or more substances combine to form one new compound?
