Akwai ruwa akan wata?Ee, yana da!Akwai wani muhimmin labarin binciken kimiyya a kwanakin nan biyu - Masana kimiyyar kasar Sin sun gano ruwan kwayoyin halitta a cikin samfurin kasa na wata da Chang 'e-5 ya dawo da shi.
Menene ruwan kwayoyin halitta?Wannan shine H₂O a cikin littafin karatun chemistry na makarantar sakandare, kuma shine tsarin kwayoyin halittar ruwan da muke sha a rayuwar yau da kullun.
Ruwa da aka samo a kan wata ≠ kwayoyin ruwa
Wasu suna cewa, ba mu riga mun san akwai ruwa a wata ba?
Wannan gaskiya ne, amma Jin Shifeng, abokin bincike a cibiyar nazarin kimiyyar lissafi ta kwalejin kimiyyar kasar Sin, ya bayyana cewa: “Ruwa a fannin ilmin kasa ya sha bamban da ruwa a rayuwarmu ta yau da kullum. ilmin kasa ya dauki OH da H₂O a matsayin ruwa; misali, idan an sami NaOH, yana kuma ɗaukar ruwa a matsayin ruwa."
Bugu da ƙari, ana samun ruwan da aka samu akan wata ta hanyar hangen nesa mai nisa da samfurori na ƙasa.
Ruwan da ke cikin ƙasan wata ya ce a baya shine ainihin wannan alamar hydroxyl "ruwa", ba kwayoyin ruwa ba a rayuwarmu ta yau da kullum. Ruwan kwayoyin halitta, H₂O, shine ruwan rayuwarmu ta yau da kullum.
“A saman duniyar wata, saboda yawan zafin jiki da kuma yanayin da ba zai yuwu ba, ruwan ruwa ba zai iya wanzuwa ba.Don haka, abin da aka gano a wannan lokaci shi ne ruwan crystalline.Wannan yana nufin cewa kwayoyin ruwa sun haɗu da wasu ions don samar da lu'ulu'u.
