What is the chemical formula of the peyote?
Peyote is a plant not a chemical substance.
What is the identity of a substance?
The identity of a substance refers to its unique characteristics that distinguish it from other substances. This includes its chemical composition, physical properties, and behavior under various conditions. Identifying a substance involves analyzing these properties to determine what it is.
What is the chemical formula and structural formula of electricity?
Electricity is not a substance with a specific chemical formula or structural formula. It is the flow of electrons through a conductor like a wire. The behavior of electricity is governed by the movement of electric charge.
