Honors Chemistry Notes Unit 1 • Matter- Anything that has mass and volume and anything that has the property of inertia. -Quantitative. -Can be solid‚ liquid‚ gas. • Inertia- Ability to resist changes in its motion. -Change in motion could be terms of speed or distance. -A car that moves after it has stopped. • Mass- The amount of matter in an object. -The balances that you use in laboratory measure mass‚ not weight. -SI unit is kilogram (kg). • Conservation of Mass- The law states that

Introduction Laser scanning is a lot like photography. A 3D scanner is a device that analyzes a real-world object or environment to collect data on its shape and possibly its appearance for example colour. The collected data can then be used to construct digital‚ three dimensional (3D) models useful for a wide variety of applications. While a camera collects colour information about surfaces within its field of view‚ 3D scanners collect distance information about surfaces within its field of view

Chapter I Introduction Background of the Study Did you know that all of us are exposed to the risk of electric shock? We are all surrounded by electrical appliances and machinery which exposed us to risk. This study allows us to know the basic information‚ the causes and effects‚ and the preventive measure because according to the National Safety Council there are about 600 to 1000 people die every year from electrocution. It continues to rank as the fourth highest cause of industrial facilities

mechanics came‚ the absolutely baffling branch of physics exploring the very smallest types of matter. The study of quantum mechanics led to some truly astounding conclusions. For instance‚ scientists found that electrons behave both as waves and as particles‚ and the mere act of observing them changes the way they behave. Revelations like this one simply defied logic‚ prompting Einstein to declare "the more success the quantum theory has‚ the sillier it looks." Einstein’s sentiments still resonate

Unit 2 Lecture Study Guide – 1) What are the parts of an atom? Where are the subatomic particles found? a) Protons‚ neutrons‚ and electrons b) Protons and neutrons are located in the center of an atom in the nucleus and the electrons are located around the nucleus. 2) How does the Atomic Mass # differ from the Atomic #? The atomic mass number is the sum of the number of protons and neutrons in the nucleus of an element and the atomic number is the number of protons that it has. 3)
