About This Chapter
HESI Admission Assessment Exam: Chemistry - Chapter Summary
This chapter contains video lessons and practice quizzes to get you up to speed for the HESI Admission Assessment Exam Chemistry subtest. Examine states of matter, the periodic table and chemical bonds. You'll also study chemical reactions, balancing chemical equations, the basic properties of chemical reactions and types of isotopes. By the end of the chapter, you should be able to:
- Provide an overview of chemical reaction catalyst
- Explain what light is
- Discuss Boyle's Law and the relationship between gas pressure and volume
- Detail Charles' Law and the gas volume and temperature relationship
- Outline the properties of water
- Explain the pH scale, buffers and solutions
- Differentiate between solutions, solvents and solutes
- Identify curves and calculations as they apply to titration
Our instructors have compiled a series of brief video lessons that explain essential concepts in a way that is easy to understand and remember. Follow along using the written transcripts or skim them to review key lesson topics. Assess what you've learned and what you still need to work on with the lesson quizzes.
1. 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.
2. The Periodic Table: Properties of Groups and Periods
How is the periodic table like the map you used on your last road trip? In this lesson, you will be introduced to the periodic table, the road map of chemists. We will discuss how the elements are organized and how you can use this organization to identify some of their major physical properties.
3. Overview of Chemical Bonds
Learn about the most common kinds of chemical bonds: ionic, covalent, polar covalent, and metallic. Discover how they form and why they hold together. Take a quiz and see how much knowledge you've held onto.
4. Chemical Reactions and Balancing Chemical Equations
In this lesson, you'll learn how to balance a chemical reaction equation using the conservation of matter law. You'll also learn how to write both word and formula equations, what the subscripts after a letter mean and what the numbers in front of compounds mean.
5. Basic Properties of Chemical Reactions
Learn how about the various components of a chemical reaction, and how those components function. Use this lesson to understand the basic properties of different kinds of chemical reactions.
6. What Are Isotopes? - Definition, Types & Examples
Not all atoms of an element are identical - atoms of the same element can have different numbers of neutrons. These different versions of the same element are called isotopes. In this lesson, we will discuss the examples and types of isotopes.
7. Chemical Reaction Catalyst: Rates & Overview
Catalysts are common in both industrial processes and in the human body. This lesson will explain how they work and why we need them. A quiz will test our knowledge.
8. What is Light?
This lesson will define and describe what light is from both technical and more common-use perspectives, discuss what the different kinds of light are, and explain why it's called radiation.
9. Boyle's Law: Gas Pressure and Volume Relationship
Have you ever wondered how an air powered water gun works? It uses the fantastic properties of gases to make a summer day more enjoyable! In this lesson, we will be discussing Boyle's Law and the relationship between pressure and volume of a gas.
10. Charles' Law: Gas Volume and Temperature Relationship
In this lesson, we will discover why the wind blows and what causes a hot air balloon to rise, a couple of the applications of Charles' Law that explain the relationship between the volume and temperature of a gas.
11. Properties of Water
Why does ice float? Why can water rise on its own against gravity in a small tube? Find out how these mysterious properties of water can be explained by hydrogen bonds.
12. The pH Scale, Solutions & Buffers
What do lemons, drain cleaner and blood have in common? They are either acids or bases. This lesson will explore acids and bases, giving examples and definitions. It will also explain how to calculate the pH and the pOH, and will define buffers.
13. Solutions, Solutes, and Solvents
Oh no! Your friend Ben just drank chili oil on a dare, and now his mouth is burning. Should he drink the ice water or vegetable oil to cool his mouth? Quick. Watch this lesson if you aren't sure.
14. Titration: Overview, Curves & Calculations
Titrations are useful to determine the molarity of a sample or a compound in a sample. We will learn how to perform a titration and how to calculate the molarity of a sample based on the titration.
