About This Chapter
Properties of Matter in Chemistry - Chapter Summary and Learning Objectives
In these lessons, you can learn about the two main ways to describe substances and find out how that guides scientists in the classification of matter. Explore the four states of matter, including solids, liquids, gases and plasma, through this chapter, finding out the variations in volume and shape. Finally, you can study the five common chemical reactions, including decomposition, combination, combustion, single-replacement and double-replacement, and learn how to predict which one to expect in given situations. This chapter is designed to teach you:
- Two ways to describe substances
- Differences between mixtures and pure substances
- Why plasma is a conductor of electricity
- How chemical reactions can be predicted
|Matter: Physical and Chemical Properties||Explain the difference between physical and chemical properties and classify various types of matter as mixtures or pure substances.|
|States of Matter: Solids, Liquids, Gases, & Plasma||Compare volume and shape in solids, liquids, gases and plasma.|
|Common Chemical Reactions and Energy Change||Define decomposition, combination, combustion, single-replacement and double-replacement reactions. Learn how matter is conserved.|
|Endothermic and Exothermic Reactions||Explain what endothermic and exothermic reactions look like and understand how to use enthalpy to predict which reaction to expect.|
1. Matter: Physical and Chemical Properties
How are substances identified? There are two major ways we can describe a substance: physical properties and chemical properties. Learn about how chemists use properties to classify matter as either a mixture or a pure substance.
2. States of Matter: Solids, Liquids, Gases & Plasma
Learn the four states of matter in the universe: solid, liquid, gas and plasma. Learn about the differences in shape and volume among the four states, which of the states is the most common and why plasma conducts electricity.
3. Common Chemical Reactions and Energy Change
This lesson covers the five common types of chemical reactions: combination, decomposition, single-replacement, double-replacement, and combustion. You will learn how to predict what kind of chemical reaction will occur. You'll also explore how matter is conserved, but energy can change.
4. Endothermic and Exothermic Reactions
Explore a chemical reaction at the molecular level. Learn about exothermic and endothermic reactions, what they look like and what happens when they occur. Understand enthalpy and how you can use it to predict whether a reaction will be exothermic or endothermic.
