PTHH: \(2Al+6HCl\rightarrow2AlCl_3+3H_2\uparrow\)
Ta có: \(n_{HCl}=0,1\cdot3=0,3\left(mol\right)\)
\(\Rightarrow\left\{{}\begin{matrix}n_{Al}=0,1\left(mol\right)\\n_{H_2}=0,15\left(mol\right)\end{matrix}\right.\) \(\Rightarrow\left\{{}\begin{matrix}m_{Al}=0,1\cdot27=2,7\left(g\right)\\V_{H_2}=0,15\cdot22,4=3,36\left(l\right)\end{matrix}\right.\)
\(n_{HCl}=0,1\cdot3=0,3mol\)
\(2Al+6HCl\rightarrow2AlCl_3+3H_2\)
0,1 0,3 0,15
\(m=0,1\cdot27=2,7g\)
\(V=0,15\cdot22,4=3,36l\)
