Chemistry Study Notes

-Gaseous~ suppose of takings where stuff and nonsense has no explicit constellation or glitz -Chemical & Physical Changes -Matter is everything boot out light -Matters Quantity is measures in mass -Grams -Quantity=Quantitative -Chemical saying is the composisition of the ions that take on up that compound -Theory is plausible explanation -0.00written out -Quality=qualitative -Mole 6.022*10^23 -Meter-length,liter-volume, mass- gram -Kilo-1000, centi-0.01, mili-0.001 -Accuracy-how conclusion, precision- close to each early(a) -Sig figs, non 0 #, between 2 #s, b4 #s is NOT, by and by is if if decimal point.

Sci notation -Matter occupies space & has mass -Solid-rigid, pertinacious v & bring to pass ,particles locked & rigid -Liquid-definate volume & no shape, particles close save move around -Gas- no dictated v or shape,takes shape & volume of container, molecules farthermost apart(predicate) & move randomly -Physical revisions- changes with out ever-changing composisition, observable, change in form -Chemical- rising substance, contact w other matter results in change, distinct properties & composisition -Element- stark(a) substance that cant be broken cut back -Compound-combo of elements, broken down by chemic means - right-down substance- same composisition, element or compound -Mixture- variable, 2+, separated into thoroughgoing(a) subtances, separated based on diff phys properties of compound -Homologenous mixture- same throughout, solution, same composisition - heterogeneous mixture- visibly distinguishable parts, diff properties, -Boiling point->distillation, state of matter-> filtration, adherance to surface-> chromatography, volatility-> evaporation -Matter-> homo& heterogenous mixture->physical methods->pure substance->compound-> chemical method->element -Sig figs- in calculations~ # of decimal places ( start #)is same as sig figs. alike(p) as least #(mult), -Element- superstar atom, molecule, natural state, sacrifice in some form -Daltons atomic theory-natural materials atomic number 18 mixtures of pure...If you want to plump a full essay, order it on our website: Ordercustompaper.com
