 Precision measure of how close a series of measures are to one another Accuracy measure of how close a measurement comes to the actual or true value of whatever is measured atomic number equals the number of protons #protons = #electrons mass number - atomic number = neutrons What is the Heisenberg uncertainty principle? *it is impossible to know exactly both the velocity and the position of a particle at the same time Theoretical Yield *How much you're SUPPOSED to get -Given: number of moles of CO2 Find: grams of CO2 Solve: multiply #moles x molar mass CO2 =grams CO2 = theoretical yield Actual Yield *found by experiment -given to you in problem Percent Yield Actual Yield/Theoretical Yield Limiting Reagent -limits or determines the amount of product that can be formed in a reaction Given: x mol of O2; x mol of C7H16 x mol of 02/leading coefficient of O2 x mol of C7H16/leading coefficient of C7H16 *whichever is smaller is the limiting reagent and will run out first* Excess Reagent -the reactant that is not completely used up in a reaction take limiting reagent and multiply it by the mole ratio e.g. 0.521 mol C7H16 x 11 mol O2/1 mol C7H16 C7H16 + 11O2 = 7CO2 + 8H2O To find the moles of products, what must be used on the left side of the equation? limiting reagent for example: Given: .521 mol of C7H16 and 11 mol of 16.2 mol of O2 *C7H16 is limiting reagent* -use C7H16 to find moles of products: CO2 and H2O Organic Chemistry study of carbon-containing substances Inorganic chemistry substances that do not contain carbon: mainly nonliving things Analytical chemistry concerned w/ composition of substances Physical chemistry theories and experiments that describe the behavior of chemicals biochemistry the study of the chemistry of living organisms e.g. blood clotting, digestion, respiration, etc. As we move from left to right across the periodic table, electronegativity.... increases As we move down the periodic table, electronegativity... decreases
