percent yield - Answers- actual yield / theoretical yield percent error - Answers- (experimental - theoretical) / theoretical write the balanced equations for the neutralization reactions of NaOH and HCl CH3COOH and OH - Answers- HCl(aq) + NaOH(aq) = Nacl(aq) + H2O (l) CH3COOH(aq) + OH-(aq) = CH3COO-(aq) + H2O(l) is the acid or base the limiting reactant in each neutralization reaction - Answers- acid does it matter if your ΔT values are in degrees celsius or kelvin when using q=m...

Chem 219: Exam 3 Questions With 100% Correct Answers Avogadro's Law equal volumes of gases at the same temperature and pressure contain equal numbers of molecules Boyle's Law Boyle's Law states that at constant temperature and moles, pressure and volume are inversely proportional. Mathematically this is written as: PV = PV Charles' Law the law that states that for a fixed amount of gas at a constant pressure, the volume of the gas increases as the temperature of the gas increases ...
