reactivity
Reactivity is the property that describes how readily a substance combines chemically with other substances. Reactivity is also referred to as the rate at which a chemical substance tends to undergo a chemical reaction.
A synthesis reaction
A mixture is a combination of substances that are combines physically, but not chemically.
A mixture is a combination of substances that are combines physically, but not chemically.
The property that describes the ability of a substance to undergo changes through physical or chemical means is known as reactivity. Reactivity refers to how readily a substance combines with others to form new substances, which can involve chemical reactions. Physical properties, on the other hand, pertain to characteristics that can be observed without changing the substance's chemical identity, such as color, melting point, and density. Together, these properties help define how substances interact and transform in various conditions.
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.
bromine combines with aluminum to produce AlBr3.
hydrophilic
When oxygen combines with another substance, it is called oxidation. Oxidation is a chemical reaction that involves the loss of electrons by a substance, resulting in the formation of an oxide.
When oxygen combines with hydrogen, water (H2O) is formed.
