Step 2: Create a System of Equations Create an equation for each element (Hg, Zn, Cl) where each term represents the number of atoms of the element in each reactant or product. Hg:1a +0b=0c+1dZn:0a+1b =1c +0dCl:0a+2b =0c+1d ...
羃2、电池Hg(l)|Zn(a1)|ZnSO4(a2)|Zn(a3)|Hg(l)的电动势:()。 螀(A)仅与a1,a3有关,与a2无关;(B)仅与a1,a2有关,与a3无关; 羈(C)仅与a2,a3有关,与a1无关;(D)与a1,a2,a3均无关。 蒆3、在25℃时,电池Pb(Hg)(a1)|Pb(NO3)2(aq)|Pb(Hg)(a2)中...
