\(n_{HCl}=0,1.1=0,1\left(mol\right)\)
PTHH: \(2A+2xH_2O\rightarrow2A\left(OH\right)_x+xH_2\)
\(2A\left(OH\right)_x+2xHCl\rightarrow2ACl_x+2xH_2O\)
=> \(n_A=\dfrac{0,1}{x}\left(mol\right)\Rightarrow M_A=\dfrac{2,3}{\dfrac{0,1}{x}}=23x\left(g/mol\right)\)
Xét x = 1 => MA = 23(Na)
\(n_{HCl}=0.1\cdot1=0.1\left(mol\right)\)
\(A+H_2O\rightarrow AOH+\dfrac{1}{2}H_2\)
\(AOH+HCl\rightarrow ACl+H_2O\)
\(n_A=n_{AOH}=n_{HCl}=0.1\left(mol\right)\)
\(M_A=\dfrac{2.3}{0.1}=23\left(g\text{/}mol\right)\)
\(A:Na\)
