a CuSO4·5H2O(s) = b CuSO4 + c H2O Step 2: Create a System of Equations Create an equation for each element (Cu, S, O, H) where each term represents the number of atoms of the element in each reactant or product. Cu: 1a = 1b + 0c S: 1a = 1b + 0c O: 9a = 4b +...
The spectra showed the variation in structures for both SO42 and H2O. Furthermore, the band positions, band intensities, and their derivatives also showed these variations in structure and the amount of each component. From the intensities of the OH bands the amounts of water lost were found ...
胆矾是一种蓝色晶体,化学式是cuso4·5h2o,胆矾受热时易失去结晶水,成为白色的无水cuso4粉末,无水cuso4易吸收水份又变成蓝色,在工业上精炼铜、镀铜等都要用胆矾。上述对胆矾的描述中,没有涉及到的是[ ]A.物理性质B.制法C.用途D.化学性质的答案是什么.用刷刷题APP,拍照
已知胆矾(化学式为CuSO4·5H2O)溶于水后形成硫酸铜溶 液,现将25g胆矾溶于一定量的水(设其质量为m,单位为克)中得到溶质的质量分数为8%的不饱和溶液,则用来完全溶解25g胆矾的水的质量(m)为 [ ]A.50gB.75gC.175gD.200g的答案是什么.用刷刷题APP,拍照搜索答疑.刷刷题(shu
