PPT-CHEMICAL EQUATIONS & REACTION STOICHIOMETRY

symbolic representation of a chemical reaction that shows reactants on left side of reaction products on right side of equation relative amounts of each with stoichiometric coefficients. I can identify the products and reactants in a chemical reaction.. I can state the law of conservation of matter.. I can determine the number of each atom in a compound based on subscripts and coefficients.. Parts of a chemical equation:. Reactants. : a substance present at the beginning of a chemical reaction. (Left side). Products. : a substance that is produced during a chemical reaction (Right Side). NOTES. MOLECULE. A . molecule. is . two . or more atoms that have chemically . combined.. Examples. : . H. 2. O. & O. 2. CHEMICAL FORMULA. A . Chemical Formula . is a description of the number and kind of atoms found in a single molecule of a substance, using the . The Arithmetic of Equations. Section 1. Section 1 Learning Targets. 12.1.1 – I can explain how balanced equations apply to both chemistry and everyday life.. 12.1.2 – I can interpret balanced chemical equations in terms of moles, representative particles, mass, and gas volume at STP.. In a chemical reaction the total mass of everything at the end of the reaction is the same as the total mass at the beginning.. The Law of Constant Composition. However you make a compound, it always contains the same elements in the same proportions by mass.. In a chemical reaction the total mass of everything at the end of the reaction is the same as the total mass at the beginning.. The Law of Constant Composition. However you make a compound, it always contains the same elements in the same proportions by mass.. Ionic compounds can form from transition metals. Transition metals do not always follow the patterns that we discussed. Can have more than one oxidation number (charge. ). To identify the charges of transition metals, roman numerals are placed in their name, directly after the transition metal. . 1. Describing a Chemical Reaction. A chemical reaction = the process by which one or more substances is changed into one or more different substance. s.. Reactants. = the original . substance(s. 10.1 . Reactions and . Equations. Evidence of Chemical Reactions. ..  . The process of which the atoms of one or more substances are rearranged to form different substances is called a . Chemical Reaction. (CRE) is the field that studies the rates and mechanisms of chemical reactions and the design of the reactors in which they take place.. Lecture. 4. Lecture 4. 2. Block 1. Mole Balances.
