## Elements, Compounds, Mixtures & Solutions - Chapter Summary and Learning Objectives

Elements, the building blocks of all matter, are everywhere you look. In this chapter, you can find out about elements and learn how to write them as symbols. These lessons also explore the various types of compounds and show how they bond and break apart while moving between solid, liquid and gaseous states. In the late 1800's, Francois Raoult studied vapor pressure and developed an equation, now called Raoult's Law, to discover the vapor pressure of a solution. In this chapter, you can meet this scientist and learn all about solutions, by investigating molarity, solubility and colligative properties. Upon completion of these lessons, you should be able to:

• Describe elements and explain how they form building blocks for other things
• Explain how elements make up compounds and discuss the properties of compounds
• Understand solutions and name several types
• Calculate dilutions, molality and molarity
• Use properties of solutions to determine molar mass

Video Objective
Using Colligative Properties to Determine Molar Mass Learn how to use freezing point depression information to figure the molar mass of unidentified substances.
Calculating Dilution of Solutions Get the formula to dilute a stock solution and find out how to get the right volume and concentration using a volumetric flask. Learn how molarity is used in a dilution equation.
Colligative Properties and Raoult's Law Understand how osmotic pressure and vapor pressure are colligative properties. Use Raoult's Law to find the vapor pressure of a solution.
Calculating Molarity and Molality Concentration Understand these expressions of concentration and how to calculate each.
The Rate of Dissolution: Factors and Definition Define miscible and immiscible, in connection to liquids. Understand dissolution and the features that affect its rate.
Solubility and Solubility Curves Define solubility, saturated, unsaturated and supersaturated.
Solutions, Electrolytes and Nonelectrolytes Find out how solutions are formed and how to calculate their molarity and mass percents.
Chromatography, Distillation and Filtration: Methods of Separating Mixtures Understand various ways mixtures may be separated.
What Are Elements? Understand how elements provide the structural basis of other things.
What Are Compounds? Explain how elements make up a compound. Discuss common properties of compounds.
Breaking Down Compounds Discuss the methods for separating compounds.
Covalent Compounds: Properties, Naming & Formation Learn the rules for naming binary covalent compounds.
Naming Ionic Compounds: Simple Binary, Transition Metal & Polyatomic Ion Compounds Name all ionic compounds. Understand cations and anions.
Ionic Compounds: Formation, Lattice Energy and Properties Learn about melting and boiling points, electricity conduction and crystal formation of ionic compounds.
