Because molecules have other chemical and physical properties than the containing atoms !
No, reacting with oxygen is a chemical property, not a physical property, of hydrogen. Physical properties are characteristics that can be observed without changing the substance's chemical composition, such as density or color. Chemical properties, on the other hand, describe how a substance can change or react to form new substances.
Yes, being composed of hydrogen and oxygen is a physical property of water. Physical properties refer to characteristics that can be observed or measured without changing the composition or identity of a substance, and the specific arrangement of hydrogen and oxygen atoms in water molecules is a defining physical property of water.
If something reacts with oxygen that is a description of a chemical property.
Yes, the fact that hydrogen can explode when ignited in air is a chemical property. It is a characteristic of hydrogen's reactivity with oxygen that results in a combustion reaction, producing energy in the form of heat and light.
No, the ability of an element to react with oxygen is a chemical property, not a physical property. Physical properties are characteristics that can be observed without changing the substance's chemical composition, while chemical properties describe how a substance interacts with other substances.
Sugar is a chemical compound. It is a carbohydrate that consists of carbon, hydrogen, and oxygen atoms. Its structure and composition give it certain physical properties, such as being sweet and soluble in water, but overall it is considered a chemical substance.
To know if something is a chemical or physical property, you need to know if it is made out of OTHER things. For example, a diamond would be a physical property because it is not made out of other things. The sugar molecule, on the other hand, would be a chemical property because it is made out of other things; carbon, hydrogen, and oxygen. So, is zinc a chemical or physical property?
Yes. oxidation is chemical property. It includes addition of oxygen or removal of hydrogen
H20 is a chemical property because it refers to the chemical formula for water, which consists of two hydrogen atoms bonded to one oxygen atom. This composition describes the specific arrangement of atoms in a water molecule, which is a characteristic of its chemical identity.
The Answer is simply that Corrosion is a Chemical property because it uses oxygen. !
Both oxygen and ethanol are molecules with the ability to form hydrogen bonds. This property allows them to interact with other molecules, influencing their physical and chemical properties.
One chemical property of hydrogen is its ability to react with oxygen to form water. Hydrogen also exhibits the property of being highly flammable when exposed to air or an oxygen-containing atmosphere.
