Tivanski In cases where data are not available for gasoline, ranges are given to indicate the different values for the individual components. Gold is a soft yellow metal, with the highest ductility and malleability of any metal. Physical and Chemical Properties . Since pesticides varies in identity, physical and chemical properties, it`s therefore logical to have them classified and their properties studied under their respective groups. 92 . 3.2 PHYSICAL AND CHEMICAL PROPERTIES Information regarding the physical and chemical properties for the gasoline mixture is located in Table 3-2. Lesson Objectives •Upon completion of this Module, Students will be able to: •Identify the characteristics of crude oil •Understand the difference between sweet and sour crude oil •Identify the adverse health effects of crude oil. Matter has both physical properties and chemical properties. It is lighter than air and is therefore collected by the downward displacement of air. Measurements made using science tools can be used to describe other physical properties of matter. The properties of alkynes pretty much follow the same pattern of those of alkanes and alkenes.
