I did this lab to find out the differences between chemical and physical changes. I also did this lab to learn the signs that would indicate the chemical reactions and physical changes. I needed to learn the odor change‚ color change‚ bubbles or gas‚ irreversible‚ temperature changes and finger prints. By the end of the lab‚ my goal was to be able to didtinguish easily the difference between chemical and physical changes. Question #1 answer. 1. Gas. 2. Dissolved in water. 3

eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species combining

Introduction What is chemical change? Chemical change is the alteration of a substance into one or more different substances with different properties (also called chemical reaction). The four different types of chemial reations are synthesis‚ decomposition‚ single displacement‚ and double displacement. Synthesis is when atoms and/or molecules combine to form larger molecules. Decomposition is when a large molecules are split into elements or smaller molecules. Single Displacement has an element
