Chemistry tutorial series on YouTube and other video collections - a summary of the major collections, including the Khan Academy, and those done by various teachers, mostly at the high school level.
Change from solid to liquid when the temperature rises to the melting point. ChemThink - This Chemistry questions site consists of a series of interactive quiz-based tutorials.
Formed from layers of sediment, and which can contain fossils. Use the solubility curve of a solute to explain observations about solutions. Explain how neutralisation reactions are used in a range of situations. COM is one of many free science sites developed by our team.
Is sodium hydroxide NaOH an acid or base? An Introduction to Surface Chemistry by Dr. It is organized in an interesting way, and is intended to support users having a wide range of backgrounds and capabilities, including home-schoolers and adult learners. Registration is required, but is free.
Draw before and after diagrams of particles to explain observations about changes of state, gas pressure and diffusion. Name simple compounds using rules: Use particle diagrams to represent oxidation, displacement and metal-acid reactions.
A change in which a new substance is formed. Use observations of a pattern in chemical reactions to predict the behaviour of an element in a group.
WikiBooks on Chemistry - Many topics in general chemistry are covered here, and are worth looking at. Match heads are made using phosphorus - a highly combustible element - that catches fire due to the friction caused when striking the match.
The text material is interesting and well written without attempting to be encyclopedic. Mercury is a metal that is liquid at room temperature. Use data to evaluate proposals for recycling materials.
Suggest ways in Chemistry questions waste products from industrial processes could be reduced. In this case, the match head contains potassium chlorate - an accelerant that speeds up the reaction.
Blues and greens are usually made through luminescence. Predict planetary conditions from descriptions of rocks on other planets. A substance that neutralises an acid — those that dissolve in water are called alkalis.In chemistry, diffusion is defined as the movement of matter by the random motions of molecules.
In a gas or a liquid, the molecules are in perpetual motion; for instance, in a quantity of seemingly immobile air, molecules of nitrogen and oxygen are constantly bouncing off each other.
Chemistry. Put on your lab goggles and start learning chemistry with these resources. Find instructions for chemistry experiments and learn about chemical reactions, elements, and the periodic table in.
Zumdahl Chemistry Study Questions. Study Questions are chapter review problems with answers. This set was written for "Honors Chemistry" which used Chemistry by Zumdahl and Zumdahl, 8th Edition (Brooks Cole, ).
The Questions and Answers are given as separate files.
You will need a session-specific link to access the self-assessment. If you will be participating in a Business Chemistry session, use the link that was emailed to you.
If you do. Questions in MCAT Chemistry" provides practice questions in all chemistry topics covered by the MCAT.
The questions and explanations are designed to teach the student to think intuitively. These are questions an educated person should be able to answer relating to chemistry in the everyday world.Download
