In this example, we solve for the final temperature when a hot metal is added to cold water.

A 15 g block of aluminum metal originally at 98 degrees Celsius is dropped into 55 g of water originally at 25 degrees Celsius. If the specific heat of water and aluminum are 4.18 J/(g C) and 0.903 J/(g C), respectively, calculate the final temperature of the metal and water.

This video series, Basic Chemistry for Biology Students, teaches the basic chemistry that you’ll need to know in your biology course, whether that’s introductory high school level, AP Biology, or even a first year college biology course.
The series covers
1. The structure of atoms (a nucleus with protons and neutrons; electrons orbiting outside in orbitals)
2. What biology students need to know about the Periodic Table.
3. The “Octet Rule” for understanding how electrons are organized into orbitals.
4. Ionic bonding (how atoms trade electrons to become charged ions, and the ionic bonds that result)
5. Covalent bonding (how atoms share electrons to form molecules)
Key chemistry terms (element, compounds, molecules, etc).
6. Understanding chemical formulas (molecular formulas and structural formulas).
Each video is tightly linked to tutorials at http://www.sciencemusicvideos.....com/basic-chemistry-

This video tutorial provides a fast review on significant figures. It explains how to count the number of significant figures by identifying nonzero digits, trailing zeros, in between zeros, and leading zeros. It also explains how to round a number to the appropriate number of sig figs when adding or subtracting and when multiplying or dividing.

In this lesson, you will learn about organic compounds in chemistry and how to visualize and name them. We will discuss what an organic molecule is, and how long chains of organic substances can be named. We will learn about alkanes form single bonds and alkenes form double bonds. We will discuss the prefixes to name hydrocarbon alkane chains, and we will use physical ball and stick models along with computer graphics to visualize how these organic molecules look in 3d space..

This chemistry video tutorial focuses on naming ionic compounds with polyatomic ions, transition metals & roman numerals.

Chemical equations use formulas and symbols to represent chemical reactions. Since matter cannot be created or destroyed, the equation must be balanced. This is done by adjusting the coefficients in front of the chemical formulas to ensure the same number of each type of atom is on both sides of the equation.

Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more. We provide teachers with tools and data so they can help their students develop the skills, habits, and mindsets for success in school and beyond. Khan Academy has been translated into dozens of languages, and 15 million people around the globe learn on Khan Academy every month. As a 501(c)(3) nonprofit organization, we would love your help!

About Atomic School:
Atomic School supports the teaching of Atomic Theory to primary school & science students .
We provide lesson plans, hands-on classroom resources, demonstration equipment, quizzes and a Teacher's Manual to primary school teachers. Animated videos that clearly explain the scientific ideas supports learning by both teachers and students. As a teacher, you don't have to look anywhere else to implement this program.

Our work has been verified by science education researchers at the University of Southern Queensland, Dr Jenny Donovan and Dr Carole Haeusler, who confirm that primary students are capable of learning much more complex scientific concepts than previously thought, and crucially, that they love it. Students run to class!

The program has been trialed in Australian schools as well as schools in the Philippines, Iran and India. It is conducted as holiday workshops at the Australian Nuclear Science and Technology Organisation, the Queensland Museum as well as the World Science Festival.
It has attracted wide media interest, including TV, radio and print, and the research data has been presented at prestigious American Education Research Association and Australian Science Education Research Association conferences.

Atomic Theory underlies all the other sciences- genetics, electronics, nanotechnology, engineering and astronomy- so an early understanding will set them up for a more successful learning sequence for all their science subjects, and support their mastery of mathematics as well. We also have extension programs that cover Biology, Physics and Astronomy to an equal depth.



About Ian Stuart (Email: ian.douglas.stuart@gmail.com):
The founder of Atomic School, Ian Stuart, taught Chemistry and Physics for 25 years at senior levels before he realized that his 8-year old son, Tom, could understand Atomic Theory at a much deeper level than he expected. After visiting Tom's class at school, he discovered that his peers could also grasp the abstract scientific concepts, as well as apply it usefully to the real world.

Ian then developed a program to teach the advanced concepts of high school Chemistry, Physics and Biology to students 10 years younger than they normally would. He found that this engaged their interest in modern science early, and sustained it through to high school and beyond. It also sets them up for future success in their academic and career paths.

Ian has a Bachelor's Degree in Chemistry from the University of Queensland and a Master's degree in Electrochemistry from the University of Melbourne.

Video transcript:

Atoms are a lot like us - we call their relationships "bonds," and there are many different types. Each kind of atomic relationship requires a different type of energy, but they all do best when they settle into the lowest stress situation possible. The nature of the bond between atoms is related to the distance between them and, like people, it also depends on how positive or negative they are. Unlike human relationships, we can analyze exactly what makes chemical relationships work, and that's what this episode is all about.

If you are paying attention, you will learn that chemical bonds form in order to minimize the energy difference between two atoms or ions; that those chemical bonds may be covalent if atoms share electrons, and that covalent bonds can share those electrons evenly or unevenly; that bonds can also be ionic if the electrons are transferred instead of shared: and how to calculate the energy transferred in an ionic bond using Coulomb's Law.

Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

Learning Objective: Use the periodic table to write electron configurations for ions.

Topics: electron configuration, cation, anion

We need to talk about how to properly sanitize your pool water with either chlorine, bromine, salt, minerals, and even Baquacil (biguanide). It would be great if you could just fill your pool with water, not add any pool chemicals, and then never worry about the water becoming a gross breeding ground for nasty contaminants and organisms? Yeah, and maybe you could keep Nessie in your pool, too. But we don’t think she’s any good at pool chemistry. Let's dive in and keep the pool water sanitized correctly!
