Chemistry Final Exam Review JUNIOR
YEAR
Activity series - correct answer-a list of elements in order of decreasing activity, the
activity series of halogens
Actual Yield - correct answer-amount of product that is experimentally obtained given
amounts of reactants
Anion - correct answer-negatively charged ion
Balanced Equation - correct answer-a chemical equation in which mass is conserved;
each side has the same #'s
Binary Compound - correct answer-compound composed of two elements
Bond dissociation energy - correct answer-energy required to break the bond between
two covalently bonded atoms; this value is usually expressed in kJ per mol of substance
Cation - correct answer-positively charged ion
Chemical equation - correct answer-expression representing a chem reaction; formulas
of the reactions (left) are connected by an arrow with formulas for the product (right)
Coefficient - correct answer-a small whole # that appears in front of a formula in a
balanced chem equation
Combination (Synthesis) reaction - correct answer-chemical change in which 2 or more
substances react to form a single new substance also called synthesis reaction
Combustion reaction - correct answer-chemical change in which an element for
compound reacts with oxygen often producing energy in light and water form
Coordinate covalent bond - correct answer-structural formula that leaves out some
bonds and or atoms; the presence of these atoms or bonds is understood
Covalent bond - correct answer-bond formed by the sharing of electrons between atoms
Decomposition reaction - correct answer-chemical change in which a single compound
is broken down into 2 or more simpler products
