Oxidation and reaction. REDOX REACTIONS 1:. Oxidation and Reduction. In the past oxidation and reduction were defined in simple terms. Oxidation - the gain of oxygen or the loss of hydrogen by an element or compound.
1. Allergic Reactions. Chemical allergy is an immunologically mediated adverse reaction to a chemical Results from previous sensitization to the chemical or to a structurally similar one. 2. Idiosyncratic Reactions. Genetically determined abnormal reactivity to a chemical.
1. Synthesis reactions. Synthesis reactions occur when two substances (generally elements ) combine and form a compound. (Sometimes these are called combination or addition reactions.) reactant + reactant 1 product Basically: A + B AB Example: 2H 2 + O 2 2H 2 O
Chemical Reactions #1. Equations. __________ equations – show the complete chemical formulas. Does not indicate ionic character __________ equation – shows all ions. Actually how the particles exist in the solution. Steps for Writing Ionic Equations.
