8)update(dict2) 把dict2的元素加入到dict中去,键字重复时会覆盖dict中的键值 AI检测代码解析 >>> dict2 { 'c' : '3333' , 'b' : 'no2' } >>> dict1 #dict2和dict1的键‘b'重复 { 'a' : 'no1' , 'b' : '2222' } >>> dict1.update(dict2) #调用update后,dict1的键'b'值被覆...
Identify the acid-base conjugate pairs in the following equilibrium reactions, and identify the acid and base species in each pair: (a) HPO_4^{2-}(aq)+H_2O(l)\rightleftharpoons PO_4^{3-}+H_3O(aq) (b) HSO_3^-(aq)+H_3O^+(aq)\rightlefth...
LED-based white-light emitters have significant potential for general illumination applications because of their advantages such as high efficiency, long life span, high reliability, reduced power consumption, cost effectiveness, and environmental benignity due to less thermal radiation and no mercury2–...
Also if the situations were reversed and I wanted to just raise my calcium could I just use part 2? Thank you for your time in advance. Steve" Steve, Sorry for this late reply. No problem using more of one component than the other in order to tweak the chemistry back in balance. Be...
