Chemical properties are determined by experiments.
They both describe substances
Yes, pH and density are physical properties. pH is a measure of the acidity or basicity of a solution, while density is a measure of the mass of a substance per unit volume. Both properties describe characteristics of a substance that can be observed and measured without changing the chemical composition of the substance.
If it's a chemical, it has chemical properties. An oreo churro (whatever unholy abomination that might be) is a mixture of chemicals, each of which will have their own chemical properties.
No, density is a physical property of matter, not a chemical property. Density is a measure of how much mass is contained in a given volume of a substance. Chemical properties relate to the behavior of a substance in chemical reactions.
A spectrometer is used to measure properties of light. The most common usage is as an instrument attached to a telescope for astronomers to measure the chemical elements in a star.
helium is chemically inert and has no chemical properties
Chemical property
Is reacts with water not a chemical properties
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
A chemical reaction (change) results in a change in chemical properties.
A chemical reaction changes the chemical properties of substances involved by forming new substances with different chemical compositions. This can result in changes in physical properties such as color, temperature, odor, and state of matter.
Helium is inert. There are no known compounds. It has no chemical properties.
