a) PTHH
Fe + 2HCl \(\rightarrow\) FeCl2 + H2
b) mHCl = \(\dfrac{m_{dd}.C\%}{100\%}=\dfrac{200.14,6\%}{100\%}=29,2\left(g\right)\)
=> nHCl = 29,2 : 36,5 = 0,8(mol)
Fe + 2HCL -----> FeCl2 + H2
m HCl=200*14.6/100=29.2 gam
n HCl =29.2/36.5=0.8 mol
a) PTHH: Fe+ 2HCl -> FeCl2 + H2
b)
\(m_{HCl}=\dfrac{200.14,6}{100}=29,2\left(g\right)\\ =>n_{HCl}=\dfrac{29,2}{36,5}=0,8\left(mol\right)\)
a, PTHH : Fe + 2HCl \(\rightarrow\) FeCl2 + H2
mHCl = \(\dfrac{200\cdot14,6}{100}\)= 29,2 g
nHCl = 29,2/ 36,5 = 0,8 mol
-mctHCl = \(\dfrac{14,6.200}{100}\) = 29,2 g
nHCl = \(\dfrac{29,2}{36,5}\) = 0,8 mol
