ACS Chemistry Final (General Chem 1 Review) Study Guide with Complete Solutions | Graded A+ | 2026/2027 Density - answer-mass / volume Conversion from celsius to kelvin - answer-K = DegC + 273.15 Conversion from DegF to DegC - answer-DegC = (5/9) (DegF - 32) Conversion from DegC to DegF - answer-DegF = (9/5)(DegC) + 32 Intensive properties - answer-Independent of amount of matter examined Extensive propertires - answer-Dependent of amount of matter examined Alcohol - answer-compund in which an H atom of a hydrocarbon is replaced by an OH funxtional group (alcohols end in -ol) Formula weight - answer-sum of the atomic weights of each atom in its chemical formula Percent composition - answer-% element = (number of atoms of that element)(atomic weight of element) / formula weight of compoundAvogadro's number - answer-6.02x10^23 Molar mass - answer-The molar mass (g/mol) of any substance is always numerically equal to its formula weight (in amu) limiting reagent - answer-the reactant that is completely consumed in a reaction Percent yield - answer-Percent yield = actual yield / theoretical yield x 100% Actual yield = amount of product actually obtained in a reaction electrolyte - answer-A substance whose aqueous solutions contain ions Strong electrolytes - answer-solutes that exist in solution completely as ions Solubility of compunds containing NO3-, CH3COO-, Cl-, Br-, I-, SO42- - answer-Exceptions: Cl-, Br- , I- : compounds of Ag+, (Hg2)2+, and Pb2+ SO4)2-: Compounds of Sr2+, Ba2+, Hg2)2+, and Pb2+ Insoluble ionic compounds: S2-, (CO3)2-, (PO4)3-, OH- - answer-Insoluble in all except S2-, and OH-: compounds of NH4+, the alkali metal cations, and Ca2+, Sr2+, and Ba2+ Insoluble in all except CO32-, PO43-: compounds of NH4+, and the alkali metal ions Ionic substances are _____ - answer-strong electrolytesMolecular substances are _____ , and ____ - answer-strong electlytes and weak acids and bases Oxidation # rules - answer--Elemental form = 0 -montatomic ion equals its charge -Oxygen= -2 except in peroxides ((O2)2-) -hydrogen= +1 except when bonded to metals (-1) -Flourine=-1 in all compounds. Activity series - answer-Any metal can be oxidized by the ions of elements below it Dillution equation - answer-M1V1 = M2V2 kinetic energy equation - answer-Ek = 1/2 mv^2 work equation - answer-w = F x d internal energy equation - answer-change in energy = internal final - internal initial Internal energy relation to heat and work - answer-change in E = q + w state function - answer-the value of a state function depends only on the present state of the system, not the path the system took to reach that state pressure-volume work equation - answer-w = -P (change in V) Enthalpy - answer-H = E + PVEnthalpies of reaction - answer-change in H = H (products) - H (reactants) heat equation - answer-q = Cs x m x change T * Cs = q / m x change T m = mass Enthalpies of formation - answer-change in Hrxn = sum of changeHf (products) - sum of change Hf (reactants) Energy of photon - answer-E = hv h = plank's constant (6.626x10^-34) v= frequency ( speed of light equation - answer-c = lamda v c = speed of light (3.00x10^8) lamda = wavelenght v= frequencymagnetic Quantum number - answer-can have values between -l and l Principal quantum number - answer-can have values of 1 ,2,3 and so forth Second quantum number - answer-can have values from 0 to (n-1)
