WebBa(OH)2·8H2O+NH4Cl化学方程式 答：你好，！ 化学方程式为：Ba（OH）2·8H2O+2NH4Cl=BaCl2+2NH3↑+10H2O 楼上的化学方程式实际上是不符合实际的，这个实验是会有氨气逸出的，有刺激性气味。 希望我的答案能帮到楼主，纯手打望采纳 … WebThe reaction is as follows: Ba(OH) 2 * 8 H 2 O + 2 NH 4 SCN -> Ba(SCN) 2 + 2 NH 3 + 10 H 2 O. The large increase in the entropy of the system (495 J/mol K) is a result of the large number of molecules present in the sum of the products. This increase in entropy overcomes the endothermicity (102.2 kJ) of the system, so the reaction is spontaneous. WebThe addition of NH4Cl to a solution of ammonia shows the effect of adding a common ion to a system at equilibrium. Equations NH3 + H2O ↔ NH4+ + OH- Addition of NH4Cl adds NH4+, driving the reaction to the left and consuming OH-. Prior to Lecture (prep time ~ 5 min.) 1.
