The Speed of Reaction.

Method Step 1 - For safety and health reasons, remove the outer cover and goggles. Step 2 - Collect the following equipment - Thermometer - Check neutral Erlenmeyer flask - Keep 1 liter crushing agent - Moisture content cylinder × 2 50 ml 25 ml Blanco - Weight marble chip marble chip CaCO 3 - hydrochloric acid Reaction with stopwatch - reaction start time delivery tube - pass Air Camp - equipment storage - Boston - water tripod heating - keep the beaker at a constant height, the hottest ice - a gentle test tube to cool the water - So please do not burn your hands.

High temperature promotes chemical reaction and promotes evaporation of moisture from food to promote Maillard reaction. As the food dries, the sugar and protein are more concentrated and the reaction is promoted. However, please make sure the cooking temperature does not exceed 180 ° C / 355 ° F. Above this temperature, different reactions, usually called combustion, ie pyrolysis, occur. People really like to bake their foods a little, but too much burning and burning will cause bitterness, and that is not attractive to your taste buds.

Introduction and Purpose: Factors that influence the rate at which a chemical reaction occurs and the rate of progression are related to the study of the chemical reaction rate that enables the study of the kinetics of chemical reactions. Therefore, collision theory qualitatively explains why it is a factor in these chemical reactions and that the relationship between reaction rates of different reactions is different. - The human body has experienced various reactions and processes necessary for human life. Human eyes have never seen a chemical reaction of the human body, but understanding these processes is very important. Without this understanding, we can not resolve or manage diseases and disorders. These processes may be small, but they have a big impact on human function

If heat is released during a chemical change or reaction, it is called an exothermic reaction. When heat is absorbed by a chemical change or reaction, it is called an endothermic reaction. The rate at which the chemical reaction takes place depends on the temperature and pressure as well as the concentration of the species involved in the chemical reaction. Substances, sometimes called catalysts, are used to promote or assist in chemical reactions. Light useful for film processing
