Yuav ua li cas paub qhov txawv tooj liab thiab liab tooj liab?

1. Xim: tooj dag yog daj lossis daj daj, ntshav tooj liab yog lub teeb liab liab.

2. Hardness: lub hardness ntawm cov hlau yog ntau dua li ntawm ib qho kev tivthaiv hlau, uas yog hais tias, lub hardness ntawm tooj dag yog loj dua.

3. Melting point: lub melting point ntawm cov alloy yog qis dua li ntawm ib qho kev tivthaiv hlau, uas yog hais tias, lub melting point ntawm tooj liab yog loj dua.

4. (1) reducibility: hydrogen yog tsim los ntawm cov tshuaj tiv thaiv ntawm tooj dag thiab tsis-oxidizing acid, thaum tooj liab tsis hnov ​​mob.

(2) galvanic cell hauv paus ntsiab lus: siv lub peev xwm sib txawv ntawm ob lub hlau, ob lub hlau txuas nrog cov xov hlau thiab muab tso rau hauv cov kua qaub uas tsis yog oxidizing los tsim cov roj electrode tsis zoo, uas yog tooj dag.
