Chemistry Review

Chapter 3.1 Measurement: a quantity that has both a ph bingle anatomy and a unit. Scientific Notation: a coefficient and 10 embossed to a power. The coefficient must of all time be greater to or equal to one and less than ten.  accuracy: measure of how conclude a measurement comes to the actual valuate of whatever is measured.  particularness: measure of how close a series of measurements are to one another. Accepted Value: the correct shelter based on reliable references Experimental Value: the encourage measured in the lab. Error: oError = experimental value veritable value Percent phantasm: oPercent Error = |error| x 100% Accepted value Significant Figures: altogether of the digits that are known, plus a last digit that is estimated. oMeasurements must always be reported to the correct rate of sig. figs. Because calculated answers oftentimes depend o n the # of sig. figs. In the determine used in the calculation. Rules For Sig. Figs: 1.All non zero digits are large  1466 = 4 sig figs 2.Zeros: oZeros between non zero digits are profound  1048 = 4 sig figs oFinal zeros are ONLY sig when decimal is used  70.4 = 3 sig figs oInitial zeros are neer significant  0.0071 = 2 sig figs 3.

Counted or defined numbers accept an infinite number of sig figs  23 people in a room or 60 mins = 1 hr In calculations, a expiration cannot be more precise than the to the lowest degree precise measurement from which i t was calculated. Chapter 3.2 S.I.! Units: oLengthmeter (m) oMass kilogram (kg) oTemperature Kelvin (K) omagazine second (s) oAmount of core mole (mol) oLuminous intensity candela (cd) oElectric authorized ampere (A)  metric unit Prefixes: oMega (M) 106 oKilo (k) 103 oDeci (d) 10-1 oCenti (c) 10-2 oMilli (m) 10-3 oMicro (µ) 10-6 oNano (n) 10-9 o...If you hope to get a full essay, hallow it on our website: OrderCustomPaper.com
