ndihme ne kimi

[keis]

ju lutem kush me ndihmon me nje detyre ne kimi?
zhvillohet elektroliza e 1 litri tretesire ujore 2M te ZnCl 2. Njehsoni masen e substancave te perftuara

[teta]

ZnCl2 = Zn +cl2 136.26 eshte masa more ku e kemi gjetur duke mbledhur masat
e elementeve M(ZnCl2) =65.36+2(35.45)=136.26

272.52 rrjedh m=n*M =2mol * 136.26


ZnCl2 = Zn +cl2
136.26----- 65.36
272.52------x
-----------------------------
x=130.72 gr masa e zinkut

[teta]

ZnCl2= Zn + Cl2
136.26 ------- 70.9
272.52-------- x
---------------------------
x=141.8 gr masa e molekules se klorit
