Ta có: \(n_{H_2SO_4}=\dfrac{150}{1000}.1=0,15\left(mol\right)\)
\(PTHH:M+H_2SO_4--->MSO_4+H_2\)
Theo PT: \(n_M=n_{H_2}=n_{H_2SO_4}=0,15\left(mol\right)\)
\(\Rightarrow M_M=\dfrac{9,75}{0,15}=65\left(g\right)\)
Vậy M là nguyên tố kẽm (Zn)
Ta có: \(V=V_{H_2}=0,15.22,4=3,36\left(lít\right)\)
Ta có: \(n_{H_2SO_4}=0,15.1=0,15\left(mol\right)\)
PT: \(M+H_2SO_4\rightarrow MSO_4+H_2\)
__0,15____0,15___________0,15 (mol)
Có: \(M_M=\dfrac{9,75}{0,15}=65\left(g/mol\right)\) ⇒ M là Zn.
\(V_{H_2}=0,15.22,4=3,36\left(l\right)\)
