1.
\(2M+nCl_2\rightarrow2MCl_n\)
Ta có :
\(n_{Cl2}=\frac{6,72}{22,4}=0,3\left(mol\right)\)
\(\Rightarrow n_{MCln}=\frac{0,6}{n}\left(mol\right)\)
\(\Rightarrow M_{MCln}=\frac{40,8}{\frac{06}{n}}=68n\)
\(\Rightarrow M_M=32,5n\)
\(\Rightarrow n=2\Rightarrow M_M=65\)
Vậy kim loại là lưu huỳnh (Zn)
2.
\(Cl_2+2NaOH\rightarrow NaCl+NaClO+H_2O\)
Ta có :
\(n_{Cl2}=\frac{11,2}{22,4}=0,05\left(mol\right)\)
\(\Rightarrow n_{NaOH}=0,1\left(mol\right)\)
\(\Rightarrow V_{NaOH}=\frac{0,1}{1}=0,1\left(l\right)\)
