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!
