Physical chemistry also called physicochemistry is the explanation of macroscopic, microscopic, atomic, subatomic, and particulate phenomena in chemical systems in terms of physical concepts; sometimes using the principles, practices and concepts of physics like thermodynamics, quantum chemistry, statistical mechanics and dynamics. Spectrophotometry To apply Beer Lamberts law to solutions and study the effect of concentration on the absorbance of a substance Cryoscopy To reinforce the concept of colligative properties and to study the effect of solute on the FP substances. Ebullioscopy To reinforce the concept of colligative properties and to study the effect of solute on the BP substances. To calculate the Gibbs free energy change of the cell reaction. To calculate the Equilibrium constant.

Background: Matter can undergo physical and chemical changes. In a physical change, matter changes its appearance physical properties but not its composition. Examples of physical changes include changes of state between solid, liquid, and gas phases , making mixtures, and changing size or shape. On the other hand, in a chemical change, matter does change its composition new substances are made. For example, the statue of liberty, which is covered with copper, turned green upon exposure to air because the copper reacts with the gases in the air to form new compounds. For each, describe the initial appearance and observation of the reaction during and after. Station Initial Observations Type of Change - Evidence to back Appearance of during and after physical or up the type of component s reaction chemical? Lead nitrate and One is yellow and Was clear before. Chemical Formation of potassium iodide one is clear Then became a Precipitate cloudy brown-green after. Potassium chlorate One is a liquid Combustion Chemical Combustion and gummy bear white, and the other is a solid red. Copper and nitric acid Brown colored Originally copper Chemical Formation of gas penny with an off- coated penny had and color change white liquid the copper added dissolved turning the nitric acid green and producing gas.

Check out all the Labster resources that can accelerate your teaching. Learn about physical and chemical changes in science by trying to help a scientist escape a dangerous planet. Become the master of both physical and chemical transformations to help a stranded scientist escape a hostile planet. In this simulation, you will learn how to classify a transformation as physical or chemical. Apply this knowledge by diving deep into some interesting examples of both changes — and prove yourself as a scientist! Now your life depends on it.

Classroom community. Activities, Lesson. Students will need to use what they learned in the background section to correctly identify the type of change and provide reasoning for why they chose that answer. All 'Science'. Aluminum and iodine White Aluminum Mixed aluminum Chemical Gas formed, and Blueish Iodine and iodine, Adding combustion water causes combustion and colored gas. Put that picture on the padlet with an explanation of WHY it's a chemical change. Formats Easel. Describe change of state. Some of these signs are: the release of energy in the form of light, heat, or sound; bubbling due to the release of gas ; odor changes; and color changes. Character education. Ebullioscopy To reinforce the concept of colligative properties and to study the effect of solute on the BP substances. Did you find this document useful? Easel Assessments. A great addition for distant and virtual learning classrooms.
