Introduction The purpose of this lab is to be able to observe the reaction rates of different chemical substances‚ by looking at which substance is the fastest reactant. This is what chemical kinetics is. Reaction rate is the change in the concentration of a reactant or product in a chemical reaction per unit time. In this lab the requirement was to be able to calculate each Average reaction rate which is the change in reactant or product concentration at a given time interval. Some equations that

FOOD SCIENCE Definition- Study of food is a separate discipline. Systematic study of nature of food materials & the scientific principles underlying their modification‚ preservation & spoilage is called as food science. INTER RELATIONSHIP- Foods are colloidal systems. Physical conditions viz. temperature & pressure affect quality. Organic compounds decompose & undergo various chemical reactions. In processed foods‚ additives added also undergo further chemical changes. Foods undergo chemical

INTRODUCTION – OBJECTIVES In this first experiment‚ we will perform 8 chemical reactions and 1 flame test in order to determine 2 things : a) firstly‚ we can know whether a reaction occurred or not. To complete our mission‚ we need to observe carefully some signs of chemical reaction’s appearance such as the change in color of solution‚ precipitate’s existence‚ the release

constantly being ignored due to the price of organic foods. The society we live in today has evolved greatly. Today‚ we are experiencing a green/organic movement. Many people wonder about the origin of this movement. In the early twentieth century‚ all food was organically grown. However‚ people didn’t know any different. Organic food was simply food. As genetic engineering replaced organic farming‚ no one thought of purposely putting chemical spray to enhance crop growth and yield. The only concern
