Sodium yog cov hlau uas ua rau cov pa oxygen thiab dej ua kom muaj zog.
Yuav ua li cas cov hlau hauv qab no cuam tshuam nrog cov pa oxygen?
Teb: Sodium hlau hnov mob hnyav nrog oxygen (O2) thiab dej (H2O). Ntau cov cua sov tsim tawm thaum cov tshuaj tiv thaiv yog li sodium ib txwm khaws cia hauv kerosene.
Cov hlau twg khaws cia hauv kerosene?
Sodium thiab Potassium yog cov hlau uas muaj zog heev thiab ua rau muaj zog nrog cov pa oxygen, carbon dioxide thiab cov dej noo nyob hauv huab cua xws li nws tuaj yeem ua rau hluav taws. Txhawm rau tiv thaiv cov tshuaj tiv thaiv tawg no, Sodium khaws cia rau hauv kerosene vim tias Sodium tsis hnov mob nrog kerosene.
Yuav ua li cas hlau reacts nrog HCl?
Potassium, sodium, lithium thiab calciumhnov mob hnyav nrog dil. HCl.
Yuav ua li cas cov hlau ua rau dej txias?
Metals xws li potassium thiab sodium hnov mob hnyav nrog dej txias. Nyob rau hauv cov ntaub ntawv ntawm sodium thiab poov tshuaj, cov tshuaj tiv thaiv yog nruj heev thiab exothermic uas cov evolved hydrogen tam sim ntawd catches hluav taws. Cov tshuaj tiv thaiv calcium uas muaj dej tsawg dua.
