Kodi Yankho la Hypertonic ndi Chiyani? Mu makalasi a chemistry ndi biology, mawu akuti hypertonic solution nthawi zambiri amamveka pokambirana za kayendedwe ka madzi kudzera mu nembanemba ya maselo, kulinganiza bwino kwa madzi m'thupi, ndi momwe amagwiritsidwira ntchito mu zamankhwala. Ngakhale zingamveke ngati zaukadaulo, lingaliro la yankho la hypertonic kwenikweni ndi losavuta kumvetsetsa ngati timvetsetsa chinsinsi: kusiyana kwa kuchuluka kwa solute ndi momwe kusiyanako "kumakokera" madzi kuti ayende. … Werengani zambiri

Katundu ndi Ntchito za Ma Silicon Compounds Silicon ndi chimodzi mwa zinthu zofunika kwambiri m'moyo wamakono, ngakhale kuti nthawi zambiri imasokonezedwa ndi "silika" kapena "silicon" m'zochitika za tsiku ndi tsiku. Silicon (Si) ndi chinthu cha mankhwala chokhala ndi atomu nambala 14 ndipo chili chochuluka mu thunthu la Dziko Lapansi, nthawi zambiri mu zinthu zamadzimadzi, osati ngati chinthu chomasuka. Ndi maziko a zinthu zosiyanasiyana—kuchokera... Werengani zambiri

Zotsatira za Mankhwala mu Njira Yodzimbiritsa Dzimbiri ndi chimodzi mwa zochitika za mankhwala zomwe zimagwirizana kwambiri ndi moyo watsiku ndi tsiku, komabe zotsatira zake zingakhale zazikulu. Kuyambira mipanda yochita dzimbiri mpaka mafelemu ofooka a magalimoto mpaka mapaipi otuluka m'mafakitale—zonsezi zingayambe ndi njira yozimbiritsa. Mwachidule, dzimbiri limatha kumveka ngati kuwonongeka kwa zinthu (makamaka zitsulo) chifukwa cha zotsatira za mankhwala kapena... Werengani zambiri

Kumvetsetsa Kagayidwe Koyamba ndi Kachiwiri Kagayidwe ka thupi ndi mndandanda wonse wa zochita za mankhwala zomwe zimachitika mkati mwa maselo a zamoyo kuti zisunge moyo.

Kawirikawiri, kagayidwe ka thupi kamagawidwa m'magulu awiri akuluakulu: kagayidwe koyambirira ndi kagayidwe kachiwiri. Zonsezi ndi zofunika mofanana, … Werengani zambiri

Ntchito ya Nessler Tube mu Analytical Chemistry Mu analytical chemistry, kulondola kwa muyeso nthawi zambiri kumatsimikiziridwa ndi momwe katswiriyo amawongolera bwino zinthu zazing'ono zomwe zimakhudza zotsatira zake. Kuwonjezera pa zida zamakono monga spectrophotometers, palinso zinthu zosavuta zagalasi zomwe zimakhalabe zofunikira chifukwa cha ntchito zawo zapadera komanso zothandiza. Chimodzi mwa zinthu zotere ndi Nessler tube. Ngakhale chikuwoneka ngati test tube wamba, ... Werengani zambiri

Kodi Acid-Base Titration ndi chiyani? Acid-base titration ndi njira yowunikira mankhwala yomwe imagwiritsidwa ntchito nthawi zambiri m'ma laboratories kuti idziwe kuchuluka kwa asidi kapena yankho la maziko. Njirayi ndi yosavuta m'malingaliro, koma yofunika kwambiri pakuchita, makamaka m'maphunziro, mafakitale, mankhwala, chakudya, ndi chilengedwe. Titration imatithandiza kudziwa kuchuluka kwa chinthu...
