Chemistry Study Notes

-Gaseous~ state of takings where material has no explicit contour or book -Chemical & Physical Changes -Matter is everything shut light -Matters sum is measures in mass -Grams -Quantity=Quantitative -Chemical Formula is the composisition of the ions that take on up that compound -Theory is plausible explanation -0.00written out -Quality= soft -Mole 6.022*10^23 -Meter-length,liter-volume, mass- gram -Kilo-1000, centi-0.01, mili-0.001 -Accuracy-how close, precision- close to eachother -Sig figs, non 0 #, amongst 2 #s, b4 #s is NOT, by and by is if if decimal point.

Sci notational system -Matter occupies space & has mass -Solid- wet, fixed v & shape ,particles locked & rigid -Liquid-definate volume & no shape, particles close but move nigh -Gas- no fixed v or shape,takes shape & volume of container, molecules farthermost apart & move randomly -Physical revisions- changes with out changing composisition, observable, change in form -Chemical- new substance, contact w other matter results in change, different properties & composisition -Element- stark(a) substance that lingo be broken down -Compound-combo of elements, broken down by chemical substance means - unmingled substance- same composisition, element or compound -Mixture- variable, 2+, separated into pure subtances, separated establish on diff phys properties of compound -Homologenous mixture- same throughout, solution, same composisition - nonuniform mixture- visibly distinguishable parts, diff properties, -Boiling point->distillation, state of matter-> filtration, adherance to surface-> chromatography, volatility-> evaporation -Matter-> homo& heterogenous mixture->physic al methods->pure substance->compound-> chemi! cal method->element -Sig figs- in calculations~ # of decimal places ( last #)is same as sig figs. akin as least #(mult), -Element- single atom, molecule, natural state, sacrifice in some form -Daltons atomic theory-natural materials are mixtures of pure...If you want to hold out a full essay, order it on our website: OrderEssay.net
