Chemistry XXI So far, our focus has been on understanding the submicroscopic structure of chemical substances and its relationship with their macroscopic physical properties . Beyond the Physical However, an essential question in chemistry is how structure determines chemical reactivity . How, when, why do substances interact to produce new substances? Nylon Synthesis

Chemistry XXI The central goal of this unit is to help you understand and apply ways of thinking that can be used to model chemical change in a system . Unit 4 How do we model chemical change? Select the best fuel Produce new synthetic materials Control the production of air pollutants What do you need to know about chemical change to complete these tasks? Why do we care?
