Kodi kuchuluka kwa mankhwala ndi monga anayeza

Timanena za zimene ndi kuchuluka kwa mankhwala monga akuti ntchito nkhani Science. Popeza ubale ndi kachulukidwe mu zimapangidwira, sayansi wapatsidwa kwambiri kuganizira, ndikofunika kudziwa tanthauzo thupi la zedi, ndi mayunitsi awo m'munda wa ntchito.

Akuti, tanthauzo, mayunitsi

Kapangidwe ka zinthu zofunika kwambiri ndi asapita kachulukidwe. Kuchita kuwerengetsera ntchito mfundo yeniyeni malinga maikwezhoni lapansi. Kuti amadziwa kuchuluka kwa nkhaniyi zimapangidwira, ife kupereka tanthauzo la mawu. Izi ndi kuchuluka thupi limene amadziwika chiwerengero cha mayunitsi zofanana (maatomu, ayoni, mamolekyulu, ndi ma elekitironi) pano m'nkhaniyo. Pofuna kumvetsa ndi kuchuluka kwa nkhaniyi, tiona kuti mtengo uyu ali lakuti yake. Mu anapezazo ndi, kutanthauza kugwiritsa ntchito mtengo, gwiritsani ntchito kalata N. Mayunitsi - mol kmol mmol.

mtengo

graders chitatu amene alibe kudziwa mmene kulemba mankhwala maikwezhoni sindikudziwa chomwe kuchuluka kwa thunthu, momwe ntchito mtengo uwu mu mawerengedwe a. Pambuyo familiarization ndi chilamulo cha kulemera zinthu zonse, kumakhaladi phindu bwino kuchuluka izi. Mwachitsanzo, zimene kuyaka wa hydrogen mu mpweya reactants chiŵerengero ndi awiri wina. Ngati wa hydrogen amadziwika misa, amene analowa ndondomeko, n'zotheka kudziwa kuchuluka kwa mpweya anatengedwa gawo mu mankhwala anachita.

Kugwiritsa mitunduyi pa pawiri ndi kuchepetsa chiŵerengero pakati pa reagents yoyambira, wosalira kuwerengetsera. kuchuluka kwa nkhaniyi umagwirira ndi chiyani? Kumbali ya masamu, zinthu izi stereochemical kuika mu aone kuti pali lapansi. Ndiko kuti, ntchito kuchita kuwerengetsera ena. Kuti momwe awerenge chiwerengero cha mamolekyulu kungakhale kovuta, izo amayanja mol. Ntchito nambala Avogadro a, akhoza kuchita masamu kuti 1 Mfuko la reagent aliyense limapangidwa 6 × 1023 mol ^-1.

kompyuta

Kodi mukufuna kudziwa zimene ndi kuchuluka kwa mankhwala? Mu sayansi, monga mtengo uwu ntchito. Ndi chofunika sayansi maselo, kumene anapezazo ndi akutsatiridwa kuthamanga gaseous buku kuchokera aone kuti pali Mendeleev-Clapeyron. Kuchita kuwerengetsera aliyense kachulukidwe, agwiritsidwa mfundo misa molar.

Pansipa amatanthauza kulemera kwa Chofanana Mole wina wa mankhwala makamaka. Kudziwa misa molar mwina kudzera atomiki misa wachibale (kuchuluka kwa kuwala kwa chiwerengero cha maatomu mu molekyulu a) kapena kudziwa kulemera kudzera mankhwala odziwika, kuchuluka (mol).

Palibe ntchito njira sukulu zimapangidwira zokhudzana kuwerengetsera wa aone kuti pali, sangakhoze kuchita popanda kugwiritsa ntchito mawu monga "kuchuluka kwa mankhwala". Kukhala aligorivimu akhoza kulimbana osati ndi kuwerengetsera nthawi zonse pulogalamu, komanso ndi ntchito chipangizo mpikisano. Kuwonjezera masovedwe ndi kulemera zinthu Angagwiritsidwenso ntchito mfundo imeneyi, kuchita anapezazo ndi buku molar. Izi ndi zoona mu nthawi imene, mogwirizana nawo zinthu gaseous.
