Observation of Chemical Change Course: General College Chemistry Purpose This experiment examines the reactions of common chemical s contained in consumer products. The purpose is to observe the macroscopic changes that these chemicals undergo. The goals of the experiment observe properties of chemical reactions and to associate chemical properties with household products. Procedure We do not have the ability to see with a naked eye individual atoms and molecules reacting during chemical changes

Physical and Chemical Properties Purpose: The Physical and Chemical Properties lab provides the opportunity to investigate the physical and chemical properties of pure chemical substances and analyze the experiment results. Procedure: In the beginning of the experiment‚ I filled two 24-well plates half way with the given chemicals and sucked up these chemicals into their labeled pipets for later use. Following this‚ I performed a number of steps on each of the four test tubes and recorded observations

Sugar cane (Saccharum officinarum) is the only crop cultivated in Sri Lanka to manufacture sugar‚ although there are crops such as coconut‚ kitul and palmyra which can be used to manufacture sugar based substances such as jaggery and treacle. Sugarcane has been cultivated in Sri Lanka since 1840s. About two decades ago‚ in 1990s‚ sugarcane was cultivated in about 25‚ 000 hectares. But‚ it has come down

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

Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance
