'Pure substance' presentation slideshows

A Matter of Fact. Mixtures, Elements and Compounds. Mixtures, elements, compounds. Scientists like to classify things. One way that scientists classify matter is by its composition. Ultimately, all matter can be classified as mixtures, elements and compounds.

Elements, Compounds, and Mixtures Notes. Pure Substances. A sample of matter that has definite chemical and physical properties. Atoms. Elements. Compounds. Molecules. Elements. pure substance that cannot be separated into simpler substances by physical or chemical means. Compounds.

The first law: transformation of energy into heat and work Chemical reactions can be used to provide heat and for doing work. Compare fuel value of different compounds. What drives these reactions to proceed in the direction they do? Why does combustion proceed spontaneously?

Matter – Properties and Changes. Chemistry – the study of matter and energy What is Matter?? What isn’t Matter??. Matter? Name some matter. Matter?. Matter?. I. Properties of Matter. Physical Properties Observed or measured w/out changing the composition of matter.

Chemistry – Sept 20, 2019. P3 Challenge – What is the definition of matter? (submit on slip of paper) Retrieve your test results. Objectives and Agenda. Objectives To distinguish solids, liquids and gases.

Matter and Change. 1.2 & 1.3 in your text book. 1.2 Matter and Its Properties. Matter - anything that has mass and takes up space. Mass - a measure of the amount of matter in an object. Volume - the amount of 3-dimensional space occupied by an object. Basic Building Blocks of Matter.

2.1: Finding Out About Matter. pure substance states of matter solid liquid gas vapor plasma elements periodic table compounds chemical names chemical symbols metals non-metals mixtures homogeneous mixtures heterogeneous mixtures solutions solute solvent alloys filtration

Welcome to Chemistry 1210. The Study of Matter. Matter - Occupies Space and has mass. The Study of Matter. Matter - Occupies Space and has mass Mass - Measure of the quantity of Matter. The Study of Matter. Matter - Occupies Space and has mass Mass - Measure of the quantity of Matter

Properties of Matter. Matter. Anything that has volume and mass. Matter Continued. Element A pure substance that cannot be broken down into simpler substances by physical or chemical means Compound A pure substance composed of two or more elements that are chemically combined.

Chemistry. The study of Chemical & Physical Properties and Changes of Matter. Chemistry. What is Chemistry? The study of the of matter What is matter? How can/will matter change when you do something to it What is Matter? Anything that has mass and takes up space (volume)

Chemistry. Properties of Matter. What is Matter?. Matter is anything that has mass and takes up space. All matter is made of particles. The type and arrangement of the particles determines the properties of the matter. Most matter exists as solids, liquids, or gases. Measuring Matter.

Classification of Matter. Chapter 1 Chemistry 2-a. Chemistry : the field of study concerned with the characteristics, composition, and transformations of matter Matter : anything that has mass and occupies space Living and non-living Macroscopic and microscopic. States of Matter. Solids.

Chapter 17. Composition of Matter. Objectives. Objective: Define substances and mixtures. Objective: Identify elements and compounds. Objective: Compare and contrast solutions, colloids, and suspensions. CLE 3202.1.5 Evaluate pure substance and mixtures. Chemistry.

Physical Chemistry. Chapter 6. Chapter 6. Reaction Equilibrium in Ideal Gas Mixtures. one-phase pure substance. (4.86)*. Physical Chemistry. Chapter 6. Chemical Potentials in an Ideal Gas Mixture. Chemical Potential of a Pure Ideal Gas. (4.36). isothermal, pure ideal gas.

The Particle Theory. The Particle Theory. The Particle Theory explains how all matter ( liquid , solid , gas ) are structured and how they react under certain conditions. The Particle Theory consists of five statements. The Particle Theory. 1. All matter is made up of very small particles.

Atoms Elements Molecules Compounds Pure Substance Mixture Solution. Atoms Are the smallest particle of an element that still retain the properties of that element. Elements are made of only one type of atom (element) . Aluminum Copper Hydrogen Fluorine.

CLASSES OF MATTER. VOCABULARY. Element – A pure substance that cannot be broken down into other substances by chemical or physical means. Compound – A pure substance made of two or more elements chemically combined.

Criteria of Purity . a) Describe paper chromatography and interpret chromatograms b) Describe how chromatography techniques can be applied to colourless substances. c) Identify substances and test their purity by melting point and boiling point determination and by paper chromatography.

Matter. The Nature of Matter. Chemists are interested in the nature of matter and how this is related to its atoms and molecules. Gold. Mercury. Chemistry & Matter. We can explore the MACROSCOPIC world — what we can see — to understand the PARTICULATE worlds we cannot see.

Why Study Chemistry?. To be better informed To be a knowledgeable consumer To make better decisions for yourself and society To learn problem-solving skills To enhance analytical thinking. Chemistry as the “Central Science”.
