Question | Answer |
A bonding pair of electrons will | define or occupy a region of space in an orbital. |
In general, each nonbonding pair, single bond, a multiple bond produces | a single electron domain around the central atom in molecules. |
The arrangement of the electron domain about the central atom is called the | Electron domain geometry. |
Most electronegative element in periodic table is | Fluorine |
Valence bond theory and hybrid orbitals allowed us to use lewis to | rationalize the geometry of molecules. |
______ describes the electrons and molecules by using specific wave functions called molecular orbitals also called (MO,MOs) | Molecular Orbital Theory |
Whenever 2 atomical orbitals orbitals overlap . . . | two molecular orbitals form. |
The substance in the greatest quanity is called _______ | Solvent |
Substance that is dissolved in solvent is called _______ | Solute |
_______ is a substance that when dissolved in water results in a solution that can conduct. | Electrolytes |
_______ Does not conduct electricity when dissolved in water | Non electrolytes |
______ process in which an ion is surrounded by water molecules arranged in a specific manner. | Hydration |
Result in the formation of an insoluble product is called .... | A precipitate reaction |
An equation showing the complete chemical formulas of the reactants and products is called . . . . . | a MOLECULAR EQUATION, because it shows chemical formulas of the reactants and products without indicating their ionic character. |
An electron is transferred between reactants this is known as ____ | Oxidation reaction. |
_______ Occurs when the oxidation number increases and reduction occurs when the oxidation number decreases. | Oxidation |
In tritrations a solution of accurately known concentration is called | a Standard solution |
*In relation to tritrations* If added gradually to another solution of an unknown concentration until the reaction between the two solutions is completed this is known as the . . . | Equivalence point |
______ are electrically conducting if the solutions are electrolytes. | Aq solutions |
3 major categories of chemical reactions that take place in AQ solutions are ____,_______,________ | Precipitation, Acid/base, Oxidation / reduction |
The reaction of a acid and base is called . . . . | a Neutralizator reaction |
_______ expresses concentration as the number of moles of solute in 1 liter of solution. | Molarity |
Adding solvent to a solution or dilution _________s the concentration of the solution without changing the total number of moles solute. | Decreases |
In ________ the oxidation and reduction happen simultaneously. | Oxidation/reduction (Redox) |
In ______ a solution of known concentration is added to a solution of unknown | Acid base titration |
________ are similar to acid base titrations, the point at when oxidation is complete is equivalent point | Redox Reactions |
