By emilyELECTRON TRANSFER. Reduction-Oxidation RX (redox) A reaction in which electrons are transferred from one species to another. Combustion reactions are redox reactions - oxidation means the loss of electrons - reduction means the gain of electrons
By PatmanBalancing Chemical Equations. CA Standards. Students know how to describe chemical reactions by writing balanced equations. Law of Conservation of Mass. In ordinary chemical reactions, the total mass of reacting substances is equal to the total mass of products
By benjaminChapter 8 Acids and Bases. 8.6 Reactions of Acids and Bases. Copyright © 2005 by Pearson Education, Inc. Publishing as Benjamin Cummings. Acids and Metals. Acids react with metals such as K, Na, Ca, Mg, Al, Zn, Fe, and Sn. to produce hydrogen gas and the salt of the metal.
By issacAtomic Binding - Molecular Bonds. Atoms are known to come together to form molecules which can be relatively simple (e.g. the hydrogen molecule H 2 ) or very complex (e.g. the DNA molecule).

By kendraCHEMICAL BONDING . Why bond? Atoms try to acquire particularly stable electron configuration (i.e the configuration maximizing binding energy) for their outer electrons form ions or molecules.
By mignonDNA Transfection into Prokaryotic and Eukaryotic Cells. Lily Chan and Tim Johnstone. Transfection: to transfer DNA into cells (either eukaryotic or prokaryotic) not through use of a viral vector. The approaches for eukaryotic and prokaryotic-cell transfection are slightly different.
