oh yes hello pasangala hi hi gopa hello okay L ready is matter around us pure order one shot okay so so yeah at l okay so yes start so yeah okay structure of at atoms and matter so yes it's matter around so first one mixtures changes okay so first one pure substance pure substance elements comps El homogeneous mixture Rous mixture okay so homogeneous mixture solution mixt suspension coll so third one changes ches properties so yeah first mind map okay so first one is matter next so mixture is further divided into homogeneous mixture erogenous mixture okay so pure substance is further divided into elements compound elements P substance sing I mean sorry P nonmetals metaloid homogeneous mixure solution erogenous suspension CID so exam yes so a form of matter having an invariant composition okay so Bas invari changing okay so hi free fire hello hi RK hi sudana hi punita hello I mean uh hi Baku correct so yes so element so next comp composed of two or more elements element oy3 so next they cannot be broken down further byic reaction it can be further broken down by chemical reactions okay element next okay so one second I mean sorry sorry so [Music] next so yes next one classification of elements so elements metals non-metals metalloids okay so Metals so is nothing but sh so next mailable is nothing but thin sheets okay Alum nextus I mean ductility so ductility nothing but nextal so next good cond of eat and electricity so metals good conductor of e to electricity okay so next one nonmetals next nonous when compared TOS iorry poor conductor of electricity and heat okay so yes so du so exam I mean l sorry so exam so the topics okay so yes next metalloids metaloid is nothing but metals and non-metals okay so metals and so next one so yeah exception so exception is nothing [Music] but iodin again nonmetal so iodin nonmetal graphite nonmetal okay so next one so yeah mixtures are formed by physical combination of two or more pure substances mixture as a variable composition the constituents can be separated easily byic [Applause] method that salad so vable so chemistry basic B to be strength in chemistry Basics so chemistry basics like of mixtures first homogeneous mixture next erogeneous mixture so homogeneous erogeneous so homogeneous uniform composition so salt water best example sugar water H in the water best example okay so so yes so NC NC NC session okay so yeah yeah math student hello hello hello so yeah graphite nonmetal correct correct correct so no problem so yesb uni so components of homogeneous mixture cannot be distinguished simple okay so next soltion solute plus solvent small am am so basic solution is nothing but homogeneous mixture okay so in the homogeneous mixture two or more comp okay so next due to very small particle size which is less than 1 nanometer so one second comments anything interesting whole book of practice NE and so yeah molecules can be both elements and compounds yes of course so that so it maybe it may not be so I'm not sure about it okay so I'm not judging your comment okay so yeah next one so yes the components of a solution include the solute minor solute particles cannot be separated from the mixture by the process of filtration and they won't settle down also okay settle down also okay down okay so next one tnd effect so yes simp the best example so next it is a phenomenon by which the path of the light becomes becomes visible in a mixture due to scattering of Light by the part to small partic solution do not show soltion supension the part of the so BAS for unsaturated Sol super saturated so like a caramel so yes correct so super saturated okay so next concentration of a solution so same same water for example dilute is nothing but less concentration okay so dilute okay so D so less concentration more concentration most concentration so yeah concentration of a solution is the so depending upon the amount of solute present in a solution we can refer it as a dilute concentrated solution so yes basic concept okay so next one so dilution is nothing but the process of the decreasing the concentration of a solute in a solution that is usually done by adding more solvent in it dilute that is nothing but decreasing solvent I mean decreasing the solute or else increasing the solvent okay so next one Concentra of solution so highlight only natural white look so skin is nothing but so yeah so super super D Ram super so n sound so yeah so stent so yeah okay percent I mean percentage of a solution nothing but so mass by mass into 100 okay volum percentage of solution volum volum volume of solute volume of solution into 100 okay okay so next one suspension so sorry so one sh rision next correct so Bas one one so yes so yeah so rision so yes next one so suspension is defined as hetrogeneous mixture so suspension suion so suspension is nothing but Mi which the solid particles are solids are dispersed in liquids so it can be solid solid I mean sorry so yes easily visible and distinguishable so next it can be separated by filtration so yeah settle down when yeah ma'am it's like rision oh one shot one super science level social L hi hi hi PM World hello he 60 by 80 so chemistry level B so hi dasan hello SS 57 of hog mix mix the first last to back errogenous mixture in which the particles are uniformly spread toward the solution and it appears to be homog it's too small to be individually seen by naked soid size okay so are bigger enough to scatter a beam of light passing through it and makes but scattering of light okay so next will not settle down when left UND disturbs so yes Max so now so Ma so in which substance collidal particles are visible most of the next one so components of collides so CID dispersed pH dis Medi dispers dispute dispersion medium okay so next one so Bas classification classify so basid is nothing but a suspension of a I mean sup soid water so next okay so yes so next so yeah solution so next next one so topic changes physical changes chemical changes so physical change so one second rectang shap again back to so yes so a physical change is a change in which the physical property such as size State shape appearance and more of the substance Alters without changing its chemical nature so so next so negative coms ignore it okay baby so yeah so next one mostly physical chains tend to be reversible so so most of the chemical changes are I mean irreversible okay but chemical chever so a chemical change is a change that brings change in the chemical properties so we get new chemical change is frequently hard to reverse than a physical change so and compared to physical change okay so burning of wood next to R of an apple formation of that is nothing but physical change and chemical change so CH chemical change okay so burning Wick is nothing but cand so stop studing so yeah so yeah so yeah important questions s00 okay fine I mean bye so bye bye
