Kuti mudziwe mmene kupeza kwambiri chuma amafuna kudziwa chilichonse wophunzira

umagwirira sukulu ndi kalozera koyambirira kwa sayansi zovuta. Kuyambira pachiyambi, ophunzira akuyesera kuti muganize momwe angathetsere kapangidwe mavuto. Tiyerekeze kuti khwerero koyamba, iwo ndi ntchito pang'ono zothandiza, koma ngati wophunzira anaphunzira Mwachitsanzo, mmene kupeza zambiri zinthu unreacted, zikhoza amati ntchito yotamandika kwambiri.

Taganizirani chitsanzo yosavuta vuto, pa maziko a zimene mungathe kudziwa mmene angathetsere zovuta zambiri. Kuganiza kuti kuyaka wathunthu wa carbon monoxide (II) inu munatenga malita 11.2. Kodi magalamu a CO2 inu ambiri kupeza?

1. kupanga anachita aone kuti pali.

NKHA + O2 = CO2

2. mwakufuna oxygen. Pali malamulo, amene nthawi zambiri angakuthandizeni. Yambani kukonza koefishienti ndi zinthu, chiwerengero cha amene ali wosamvetseka maatomu. Pankhaniyi oxygen molekyulu NKHA. Kuchiyika icho chinthu 2. Popeza kumanzere anapanga maatomu mpweya awiri, ndi bwino - chimodzi, kenako kupulumutsa CO2 2. Choncho, timapeza:

2 Akorinto + O2 = 2CO2

Monga mukuonera, anachoka ndi ufulu mbali ya maatomu anayi oxygen. Kaboni komanso kusungidwa mu muyezo. Choncho equalized bwino.

3. Kenako, muyenera kupeza kuchuluka kwa O2. Khama la misa maselo ophunzira kwambiri wolemera ndi zovuta kumbukirani, timagwiritsa ntchito njira zosiyana. Kumbukirani kuti pali molar kuchuluka umene uli wofanana 22,4 L / Mole. Muyenera kupeza mmene timadontho-timadontho zambiri (n) adalowa zimene :. N = V / V mamita Ifeyo, N = 0,5 mol.

4. Tsopano akatunge ndi mchimake. Kuchuluka kwa mpweya omwe adalowa theka anachita N (CO2). Izi motere chakuti 0.5 timadontho-timadontho / Mfuko la 1 = × / 2. A chiŵerengero yosavuta makhalidwe awiri zathandiza kuti anthu aone kuti pali ufulu. Tikaona × = 1, tikhoza kupeza yankho la funso mmene kupeza misa.

5. Mogwirizana ndi kuyamba adzakhala ndi kukumbukira chilinganizo lina: mamita = M * N. The variable anapeza, koma chochita ndi M? Molar misa - ndi experimentally anapereka wachibale wa hydrogen. Iwo amaimira kalata M. Tsopano tidziwa kuti mamita (CO2) = 12 g / mol * 1 Mole = 12 ga Izo zinamugwira ayankhe. Monga mukuonera, palibe zovuta.

ntchito n'zosavuta kwambiri zosiyanasiyana ena. Koma chinthu chachikulu - kudziwa mmene kupeza misa. Tangoganizani molekyulu ndi zinthu. Iwo akhala ankadziwikanso kuti Mole limapangidwa 6 * 10 ^ 23 mamolekyulu. Pa nthawi yomweyo mu nthawi mchitidwe tebulo pali anaika kulemera pa 1 mol. Nthawi zina m'pofunika kuwerengera misa molar wa thunthu. Tiyerekeze M (H20) = 18 gm / Mole. Ndilo molekyulu wa hydrogen ali M = 1 galamu / mol. Koma madzi muli ma atomu aŵiri a H. Komanso, musaiwale za kupezeka kwa mpweya, amene amatipatsa zina magalamu 16. Polongosola mwachidule timapeza 18 gm / Mole.

The ongolankhula misa mawerengedwe adzakhala kenako kukhala kugwiritsa ntchito. Makamaka ophunzira amene ali kuyembekezera msonkhano mankhwala. Usaope mawu, ngati mukuphunzira sukulu sanali pachimake. Koma ngati umagwirira - mbiri mutu wanu, si bwino kuthamanga mfundo zofunika. Kotero, tsopano inu mukudziwa momwe kupeza misa. Kumbukirani kuti umagwirira Nkofunika kukhala chogwirizana ndi woganizira munthu amene si yekha akudziwa ena ma aligorivimu, komanso amadziwa mmene angadzigwiritsire ntchito izo.
