PTHH: Mg+2HCl ----> MgCl2+H2
nH2=3,36/22,4= 0,15 mol
Theo pthh ta có: nMg=nH2=0,15 mol
=> mMg=0,15.24= 3,6 (g)
PTHH : \(Mg+2HCl->MgCl_2+H_2\)
---------0,15----0,3-------------0,15-----0,15
Ta có nH2 =0,15 mol
theo PTHH => nMg =0,15 mol
=> mMg =0,15.24=3,6 gam
Vậy...
PTHH: Mg + 2HCl -> MgCl2 + H2
Theo PTHH và đề bài, ta có: \(n_{Mg}=n_{H_2}=\dfrac{3,36}{22,4}=0,15\left(mol\right)\\ =>m_{Mg}=0,15.24=3,6\left(g\right)\)
Ta có: \(n_{H_2}=\dfrac{3,36}{22,4}=0,15\left(mol\right)\\ PTHH:Mg+2HCl->MgCl_2+H_2\uparrow\\ =>n_{Mg}=n_{H_2}=0,15\left(mol\right)\\ =>m_{Mg}=0,15.24=3,6\left(g\right)\)
