What is the percent yield of the decomposition reaction if 9.9 grams of Pb(NO3)2 is heated to give 5.5 grams of PbO? 2Pb(NO3)2(s) arrow 2PbO(s) + 4NO2(g) + O2(g) What is the theoretical yield in grams of CuS fo...
Find out what type of reaction occured. Read our article on how to balance chemical equations or ask for help in our chat. Examples Mo2 + H2O = O2 + MoH COF3 = COF2 + F2 Al + K3PO4 = AlO4P + K Zn + Cl2 = Zn2 + Cl2 NaNO3 + H2O = H2 + O2 + NaNO3 KI ...
either negative or positive, indicates that the variable has a large impact on Pb2+removal, whereas the near zero effect means that the variable has little or no effect. The results indicated that the high levels of initial Pb2+ion concentration and temperature positively affected on...

摘要:为了快速测定水样中的微量Pb(Ⅱ),将生物染色剂孔雀绿(BG)浸渍在定量滤纸上制备成铅检测试纸并研究了试纸与Pb(Ⅱ)的反应条件。结果表明,在水样中依次加入抗坏血酸、KI和HNO3,调解其浓度分别为0.010、0.15和0.40mol・L-1,Pb(Ⅱ)与试纸上的生物染色剂孔雀绿...
Balance Pb(NO3)2 + SO2 = PbS + O2 + NO2 Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every elem...
