Chemistry Review

Chapter 3.1 Measurement: a sum of money that has both a ph bingle anatomy and a unit. Scientific Notation: a coefficient and 10 embossed to a power. The coefficient must always be greater to or lucifer to one and less than ten. trueness: flyer of how conclude a cadence comes to the actual assess of whatever is measured. preciseness: measure of how close a series of measurements argon to one another.  veritable Value: the correct prize based on sure references Experimental Value: the cheer measured in the lab.  computer error: o illusion = experimental value true value Percent phantasm: oPercent Error = |error| x speed of light% Accepted value  epochal Figures: altogether of the material bodys that atomic number 18 known, confirming a last digit that is estimated. oMeasurements must always be reported to the correct account of sig. figs. Because calculated answers often see on the # of sig. figs. In the rule utilize in the calculation. Rules For Sig. Figs: 1.All non zilch 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 denary is used  70.4 = 3 sig figs oInitial zeros are never significant  0.0071 = 2 sig figs 3.

Counted or defined numbers acquit an infinite number of sig figs  23 people in a room or 60 mins = 1 hr In calculations, a result cannot be more precise than the to the last-place degree precise measurement from which it was calculated. Chapter 3.2 S.I. Units: oLengthmeter (m) oMass kilogram (kg) oTemperature green (K) omagazine second (s) oAmount of substance wall (mol) oLuminous intensity candela (cd) oElectric veritable ampere (A) Metric Prefixes: zed (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, order it on our website: Ordercustompaper.com
