解析 B。首先写出反应方程式中各元素的化合价变化,铝元素从 0 价变为+3 价,氢元素从+1 价变为 0 价。根据化合价升降守恒,铝原子和氯化氢分子的比例为 1:3,生成氯化铝和氢气的比例为 1:1.5,化为整数比即 2Al + 6HCl → 2AlCl₃ + 3H₂。所以氯化铝的系数是 2。
Al + HCl = AlCl3 + H2 is a Single Displacement (Substitution) reaction where two moles of solid Aluminium [Al] and six moles of aqueous Hydrogen Chloride [HCl] react to form two moles of aqueous Aluminum Chloride [AlCl3] and three moles of Dihydrogen [H2] gas Reaction Type Single Displace...
2. The reaction between aluminum and hydrochloric acid to form aluminum chloride and hydrogen gas: 2Al + 6HCl -> 2AlCl3 + 3H2。 In this equation, two aluminum atoms react with six hydrochloric acid molecules to produce two molecules of aluminum chloride and three molecules of hydrogen gas. ...

reaction mechanismExperimental reaction rate data for the Al/HCl system are very scarce. Such data are needed for the comprehension and for the numerical simulation of the combustion of aluminum particles as encountered in solid segmented motors. Toward this end, we have examined the homogeneous ...
(1), and the use of HF to expose the impurity sites in the SiO2 layer before dissolved by HCl solution, as given by Eqs. (2), (3). However, the synergism and interaction effect between HCl and HF for the removal of metal from DWSSP waste remains unknown. For this reason, the ...
