a, PT: \(Fe+2HCl\rightarrow FeCl_2+H_2\)
b, Ta có: \(n_{Fe}=\frac{5,6}{56}=0,1\left(mol\right)\)
Theo PT: \(n_{H_2}=n_{Fe}=0,1\left(mol\right)\)
\(\Rightarrow V_{H_2}=0,1.22,4=2,24\left(l\right)\)
c, Theo PT: \(n_{HCl}=2n_{Fe}=0,2\left(mol\right)\)
\(\Rightarrow V_{ddHCl}=\frac{0,2}{1}=0,2\left(l\right)\)
Bạn tham khảo nhé!
a) PTHH: \(Fe+2HCl\rightarrow FeCl_2+H_2\)
b) Ta có: \(n_{Fe}=\frac{5,6}{56}=0,1\left(mol\right)\)
\(\Rightarrow n_{H_2}=0,1mol\) \(\Rightarrow V_{H_2}=0,1\cdot22,4=2,24\left(l\right)\)
c) Theo PTTH: \(n_{HCl}=2n_{Fe}=0,2mol\)
\(\Rightarrow V_{HCl}=\frac{0,2}{1}=0,2\left(l\right)=200\left(ml\right)\)
