Chem 103- module 3 UPDATED ACTUAL
Exam Questions and CORRECT Answers
Law of Conservation of Matter - CORRECT ANSWER -matter cannot be created or
destroyed
Reactant - CORRECT ANSWER -Substances undergoing the reaction
Products - CORRECT ANSWER -Substances that are generated by the reaction
Solution - CORRECT ANSWER -Homogenous mixture of two more substances
Solvent - CORRECT ANSWER -Component of solution that has a greater concentration
Solute - CORRECT ANSWER -Component of solution that has a lesser concentration
What trades do solutions exhibit? - CORRECT ANSWER -The homogenous, the
components of a solution are dispersed on a molecular scale, the dissolve salute, and a solution
will not settle out or separate from solvent
What happens when an ionic compound is mixed with water - CORRECT ANSWER -the
different ions of the compound are pulled apart , or dissolved, by the water molecules.
ion-dipole attraction - CORRECT ANSWER -electrostatic attraction between an ion and a
polar molecule
Electrolyte - CORRECT ANSWER -Substances that produce ions in solution when
dissolved
, Non-electrolytes - CORRECT ANSWER -substances that form no ions in water and
cannot conduct electricity
Strong electrolytes - CORRECT ANSWER -If the physical or chemical process generates
is 100% efficient
Weak electrolytes - CORRECT ANSWER -Small fraction of dissolve, substance
undergoes I am productivity process
Precipitation reaction - CORRECT ANSWER -Went to aqua solutions are mixed to form
an insoluble product
Endothermic - CORRECT ANSWER -(of a chemical reaction or compound) occurring or
formed with absorption of heat
Are ionic compounds endothermic - CORRECT ANSWER -Yes, Ionic compounds with
stronger bonds require greater amount of energy to separate anions and cations (higher melting
point)
Dissolving - CORRECT ANSWER -Breaking apart, ionic lattice, but also requires
saluation
Saluation - CORRECT ANSWER -Energy releasing process as solvent molecules,
surround and interact with an ions and ions
Hydration - CORRECT ANSWER -solution process with water as the solvent
Exothermic reactions - CORRECT ANSWER -Chemical reactions that release a
significant amount of heat.
