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.
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.
A combination of two substances that do not chemically react can be a mixture or a solution.When two substances combine to form a new substance, it is said that a chemical reaction has occurred.

two
When an acid and a base undergo neutralization, the two substances formed are water and a salt.
Substances formed in chemical changes have different physical and chemical properties compared to the original substances. This can include changes in color, odor, state of matter, melting/boiling points, and reactivity. The chemical composition of the new substances is also different from the original substances.
Compound is formed by the chemical combination of two or more substances.
Compound is formed by the chemical combination of two or more substances.
A new substance is obtained.
a compound
When two or more substances are combined, a mixture is always created. In a mixture, the individual components retain their distinct properties and can often be separated by physical means. In some cases, if a chemical reaction occurs, new substances called products may be formed. However, the initial combination itself results in a mixture.
Mixture
A compound is formed when two or more other substances are combined and a chemical change takes place. Pure water would be an example of a compound.
A mixture is formed from compounds but both are formed from atoms.
Two substances that are brought together, but not chemically combined to create a new substance, form a mixture.
two or more subsantes (a mixture of substances) !
mixed substances
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.
