Mass izinyo? Itheyibhile ikuncede!

Chemistry - inzululwazi soxhapazo. Ngengqiqo ukuba ncakasana, yokwenene, echaza ubunyani kuyo, okanye encinane kakhulu okanye ebanzi kakhulu. abaninzi kakhulu lali- inani Ngama-23. Ngokwenene ukuba lukhulu. Kwaye ngenxa yokuba iiyunithi ezininzi kangaka (izabelo) uqulathwe kwenye adla wenkqu. Ngaba ungathanda ukwenza izibalo kunye amanani amakhulu kangaka? Oku kungelula. Kodwa kule mihla nawuphi na umfundi usombulula iingxaki chemistry ngokusebenzisa iphepha kunye wokubala elula. Oku ngenxa kunokwenzeka ukuba lula ulwimi okhethekileyo, adalwe ekhemisi. Kwaye enye ngamabinzana eziphambili olu lwimi - "ubunzima izinyo".

Xa definition, ifomula

Ukumisela ubunzima izinyo ulula: oluninzi eziphathekayo ukuba yahlulwe ubuninzi chemical. Oko kukuthi, uya kwazi ukuba ubunzima enkulu enye adla ukwimo. Kukho enye indlela yokwenza izigqibo ubunzima izinyo, kodwa eyona nto ibalulekileyo - musa bedidekile. mass izinyo ke ngamanani lilingane atomic okanye ubunzima eziphilayo. Kodwa loo nto iiyunithi ezahlukeneyo.

Ngokubanzi, kutheni?

Kwezinye iimeko, ungafuna ubunzima izinyo? A Umzekelo classic - imfuneko ukuchonga kweziyobisi ifomula. Asizizo zonke izinto hayi zonke iimeko kumiselwa ngeempawu imichiza kunye nenkangeleko, ngamanye amaxesha kuyimfuneko ukuba siqwalasele ngoyena oluninzi. Ukuba uyazi nelona nani kwezinto, sinako ukubala uhlobo athom kunye zinkulu kwazo kweziyobisi. Kwaye udinga uncedo yemichiza endala. Ngokwenene endala kakhulu. Of Mendeleev.

imiqondo zonxibelelwano

Le theyibhile iya kusinceda sisazinzulu enkulu? ubunzima izinyo osisiqu ngenani elingana nuclear (izinto atomic zesinyithi ehlambulukileyo) okanye ubunzima eziphilayo, kodwa ulinganiswa kwezinye iiyunithi. Olu hlobo luza kuthetha iyeza grams adla nganye, eziphilayo - ngeeyunithi mass atomic. Njani na ukuba la manani ayafana? Amaxabiso ozibona netafile eziqalelo zabalwa empirically. uhlobo ngalinye athom ukuba bahlaziye ubone ubunzima yayo kwiiyunithi lula. Ngoko ke, wena awuboni thabatha isidanga wamashumi omabini anesixhenxe, kunye neenombolo kakhulu onesidima, ngokufuthi phakathi kweeyunithi kunye namakhulu. Kukho imiba heavyweights, kodwa ngokuqhelekileyo engakhankanywa kwiincwadi zesikolo iingxaki.

Ukuba akukho onke amanani kwiincam zakho zomnwe

Yaye kuthekani ukuba impahla ubunjwe molekyuli, yaye niyazi ukuba yintoni leyo? Njani bahlola ubunzima izinyo kwento, ukuba akukho ubunzima ubuninzi kunye neemeko lwemichiza ingxaki ngexesha elinye? Oku uvele uhlobo ngalunye kwezi athom (izinto) itafile nande inani yamatye atomic-athom kwi molecule ukuba izinto ezahlukeneyo. Kwaye kwangoko dibanisa nje up - kwaye ufumane ubunzima eziphilayo, nto leyo eya kuba ncam nolovane. Kuba ekhemisi abaselula mihla yonke sele zilungiselelwe - kuba compound ezaziwayo ifomula ukubala ixabiso olifunayo akukho ngxaki.

Ukuba uqonde chemistry, uya kukufumanisa kulula kakhulu. Isihlabo iphambili ngexesha kuphuhliso kwale nzululwazi - kukufunda, khumbula iimpawu kwezinto ezithile, kodwa iinkqubo jikelele kunye neenkcazelo - nje ndawo. Wakuba uyaqaphela potreniruetes - ungaze ebomini bam ukuba bedidekile.
