PTHH: \(BaCO_3+2HCl\rightarrow BaCl_2\downarrow+H_2O+CO_2\\ 0,25mol:0,5mol\rightarrow0,25mol:0,25mol:0,25mol\)
\(n_{HCl}=0,5.1=0,5\left(mol\right)\)
a. \(V_{CO_2}=0,25.22,4=5,6\left(l\right)\)
b. \(V_{BaCl_2}=0,25.22,4=5,6\left(l\right)\)
\(CM_{BaCl_2}=\dfrac{0,25}{5,6}=0,05\left(M\right)\)
(?)
\(n_{HCl}=1\cdot0,5=0,5\left(mol\right)\)
PTHH :
2HCl + BaCO3 ----> BaCl2 + H2O + CO2
..0,5.......0,25...........0,25.........0,25.....0,25..(mol)
\(\Rightarrow V_{CO_2}=0,25\cdot22,4=5,6\left(l\right)\cdot=5\)
\(CM_{BaCl_2}=\dfrac{0,25}{0,5}=0,5M\)
Đổi 500ml = 0,5l
\(n_{HCl}=0,5.1=0,5\left(mol\right)\)
PTHH: \(BaCO_3+2HCl\rightarrow BaCl_2\downarrow+H_2O+CO_2\uparrow\)
a. Theo PT ta có: \(n_{CO_2}=\dfrac{0,5.1}{2}=0,25\left(mol\right)\)
\(\Rightarrow V_{CO_2}=0,25.22,4=5,6\left(l\right)\)
b. Theo PT ta có: \(n_{BaCl_2}=\dfrac{0,5.1}{2}=0,25\left(mol\right)\)
\(\Rightarrow C_{M_{BaCl_2}}=\dfrac{n}{V}=\dfrac{0,25}{0,5}=0,5\left(M\right)\)
