Co2O3+SO32-+4H+=2Co2++SO42-+2H2O,滤渣1的成分可能是CaSO4,故答案为:Co2O3+SO32-+4H+=2Co2++SO42-+2H2O;CaSO4;(3)“氧化”中加Co2O3的作用是将Fe2+氧化为Fe3+,故答案为:将Fe2+氧化为Fe3+;(4)“调pH”为4.7-6之间,则滤渣2为Fe(OH3、Al(OH)3,故答案为:Fe(OH3、Al(OH)3;(5)...
例子:Fe, Au, Co, Br, C, O, N, F。 离子电荷尚未得到支持,将被忽略。 替换不可改变的组以避免歧义。例如,C6H5C2H5 + O2 = C6H5OH + CO2 + H2O不能被平衡,但XC2H5 + O2 = XOH + CO2 + H2O可以。 不需要复合状态[如(s)(aq)...

We investigated the magnetic correlations in the Fe spin ladder system Na 2Fe 2(C 2O 4) 3(H 2O) 2 by magnetic susceptibility and 57 Fe Mössbauer spectroscopy between 2 and 310 K. The susceptibility exhibits a broad maximum at about 20 K indicating antiferromagnetic coupling and a S=0...
High field level crossing studies on spin dimers in the low dimensional quantum spin system Na2T2(C2O4)3H2O)2 with T=Ni,Co,Fe,MnIn this paper we demonstrate the application of high magnetic fields to study the magnetic properties of low dimensional spin systems. We present a case study ...
Step 3: Solve For All Variables Use substitution, Gaussian elimination, or a calculator to solve for each variable. Simplify the result to get the lowest, whole integer values. a = 1 (Na2C2O4) b = 1 ((NH4)2Fe(SO4)2*6H2O) c = 1 ...
