CHEM 1201 Final Exam With 100% Correct And Verified Answers 2024

CHEM 1201 Final Exam With 100% Correct And Verified Answers 2024 Diatomic Molecule (2.2) - Correct Answer-molecule made up of 2 identical atoms (ex: H2, N2, O2) Molecular Compounds (2.2) - Correct Answer-compounds composed of molecules Molecular Formula (2.2) - Correct Answer-give the exact number of atoms (ex: H2O2, CH4) Empirical Formula (2.2) - Correct Answer-gives the lowest and most simplified version of numbers (ex: HO, CO, CH4) Ionic Compound (2.2) - Correct Answer-Between a metal and nonmetal, when written their powers are reversed with the atom next to them (ex: Mg2N3, Mg has 3 charge and N has 2 charge) Combination Reactions (3.1) - Correct Answer-2 or more substances react to form one product (A+B=C) Decomposition Reaction (3.1) - Correct Answer-when 1 substance breaks down into 2 or more substances (C=A+B) Combustion Reactions (3.1) - Correct Answer-Involve oxygen reacting with a hydrocarbon to production CO2 and H2O (CH4 + 2 O2 = CO2 + 2 H2O) this produces a flame Percent Composition (3.1) - Correct Answer-Formula: %Element=(number of atoms)(atomic weight)/(molecular weight of compound) X 100 Avogadro's Number (3.1) - Correct Answer-6.022 X 10^23 of any unit Molar Mass (3.1) - Correct Answer-grams/mole strong Electrolyte (4.1) - Correct Answer-dissociates into ions when dissolved in water, strong electrolyte is aqueous, have strong acids and bases, ionic compound weak electrolyte (4.1) - Correct Answer-may dissolve in water but doesn't dissociate completely into ions, equations indicate chemical equilibrium (reaction goes both forward and backward) Non-electrolyte (4.1) - Correct Answer-doesn't dissociate in water, only composed of non-metals formed from molecular compounds (covalent compound) Precipitation Reactions (4.1) - Correct Answer-result in formation of insoluble product, pairs of oppositely charged ions attract each other Metathesis (exchange) reaction (4.1) - Correct Answer-swapping ions in solution, 1)Molecular Equation (ME) where all compounds labeled aq or s and balanced out. 2)Complete Ionic Equation (CIE) where the aq compounds are written in expanded form but the s compounds aren't. 3)Net Ionic Equation (NIE) cross out the atoms that are the same on both sides (spectator ions)
