PSU Chem 111: Experiment 7 part 1 Questions and Answers.

Ionic Compound - Answer A chemical compound composed of cations and anions combined so that the charge is equal Molecule - Answer A neutral aggregate of two or more atoms held together by covalent bonds. Polar Bond - Answer A covalent bond in which the bonding electrons are more strongly attached by one of the bonding atoms creating a partial positive and negative ends. There is some degree of ionic character in this type of bond. Nonpolar Bond - Answer A covalent bond in which the bonding electrons are equally shared by two atoms, so there are no partial positive and negative ends Polar Molecule - Answer A molecule that possesses a net dipole moment Nonpolar Molecule - Answer A molecule that does nor possess a net dipole moment Solution - Answer A homogenous mixture of two or more substances Mixture - Answer A combination of two or more substances in which the substances retain their identity Precipitate - Answer An insoluble solid product that separates from the solution Molecular Equation - Answer A reaction equation that shows the complete chemical formulas of all reactants and products Full Ionic Equation - Answer A reaction equation that shows all soluble strong electrolytes in their ionic forms Net Ionic Equation - Answer A reaction equation in which all spectator ions are removed leaving only the ions and molecules directly involved in the reaction Spectator Ions - Answer Ions that are not involved in the overall reaction
