a) \(n_{Mg}=\dfrac{12}{24}=0,5\left(mol\right)\)
PTHH: Mg + 2HCl --> MgCl2 + H2
0,5--->1------>0,5---->0,5
=> VH2 = 0,5.22,4 = 11,2 (l)
mHCl = 1.36,5 = 36,5 (g)
b) mMgCl2 = 0,5.95 = 47,5 (g)
`Mg + 2HCl -> MgCl_2 + H_2`
`0,5` `1` `0,5` `0,5` `(mol)`
`n_[Mg]=12/24=0,5(mol)`
`a)m_[HCl]=1.36,5=36,5(g)`
`V_[H_2]=0,5.22,4=11,2(l)`
`b)m_[MgCl_2]=0,5.95=47,5(g)`
