CHEM 101 FINAL EXAM WITH
VERIFIED ANSWERS GRADED
A+ 2026
Ionic Compound - answer-a compound composed of positive and negative ions that are
combined so that the numbers of positive and negative charges are equal
Covalent Compound - answer-a chemical compound formed by the sharing of
electrons
The Ideal Gas Law - answer-PV = nRT.
Tells you how a gas responds to a change in its physical conditions. change P, V or T, and
the others adjust
Stoichiometry - answer-that portion of chemistry dealing with numerical relationships in
chemical reactions; the calculation of quantities of substances involved in chemical
equations
Electrolytes - answer-chemical substances that develop an electric charge and are able
to conduct an electric current when placed in water; ions
Strong Acids - answer-HCl, HBr, HI, HNO3, HClO4, H2SO4
Dissociates completely in water
Weak Acids - answer-HF, HCN, HC2H3O2, H2S, H2CO3, HClO
Doesn't dissociate completely in water
Net Ionic Equation - answer-an equation for a reaction in solution showing only those
particles that are directly involved in the chemical change
, Spectator Ions - answer-ions that do not take part in a chemical reaction and are found
in solution both before and after the reaction
Acid - answer-a substance that increases the hydrogen ion concentration of a solution
Base - answer-eat protons
consume H+ ions when fin water
metal hydroxides are the most common
1st Law of Thermodynamics - answer-The principle of conservation of energy. Energy
can be transferred and transformed, but it cannot be created or destroyed.
2nd Law of Thermodynamics - answer-entropy of the universe is always increasing
Kinetic Energy - answer-energy of motion
Potential Energy - answer-energy stored due to an object's position or arrangement
Enthalpy - answer-the amount of thermal energy emitted or absorbed by a chemical
reaction, under conditions of constant pressure
Endothermic Reaction - answer-a chemical reaction accompanied by the absorption of
heat
Exothermic Reaction - answer-a reaction that releases energy in the form of heat
Specific Heat - answer-the heat required to raise the temperature of one gram of a
substance one degree centigrade
