CO2 + Ba(OH)2--> BaCO3 + H2O
Ta có nCO2=5,6/22,4=0,25 mol = nBa(OH)2=nBaCO3
=> CM ddBa(OH)2=0,25/0,1=2,5M
=> mBaCO3=0,25.197=49,25 g
Ba(OH)2 + 2HCl--> BaCl2 + 2H2O
Ta có nHCl=2 nBa(OH)2=0,25.2=0,5 mol
=> mddHCl=0,5.36,5.100/20=91,25 (g)
CO2 + Ba(OH)2 → BaCO3↓ + H2O (1)
\(n_{CO_2}=\dfrac{5,6}{22,4}=0,25\left(mol\right)\)
Theo PT1: \(n_{Ba\left(OH\right)_2}=n_{CO_2}=0,25\left(mol\right)\)
\(\Rightarrow C_{M_{Ba\left(OH\right)_2}}=\dfrac{0,25}{0,1}=2,5\left(M\right)\)
Theo PT1: \(n_{BaCO_3}=n_{CO_2}=0,25\left(mol\right)\)
\(\Rightarrow m_{BaCO_3}=0,25\times197=49,25\left(g\right)\)
Ba(OH)2 + 2HCl → BaCl2 + 2H2O (2)
Theo PT: \(n_{HCl}=2n_{Ba\left(OH\right)_2}=2\times0,25=0,5\left(mol\right)\)
\(\Rightarrow m_{HCl}=0,5\times36,5=18,25\left(g\right)\)
\(\Rightarrow m_{ddHCl}=\dfrac{18,25}{20\%}=91,25\left(g\right)\)
nCO2 = \(\dfrac{5,6}{22,4}\)= 0,25mol
CO2 + Ba(OH)2 -> BaCO3 + H2O
0,25-->0,25------>0,25
V= 100 ml = 0,1 (l)
CM = \(\dfrac{0,25}{0,1}\) = 2,5M
mBaCO3 = 0,25. 197 = 49,25 g
Ba(OH)2 + 2HCl -> BaCl2 + H2O
0,25------->0,5mol
=>mHCl(dung dịch) = \(\dfrac{0,5.98.100}{20}\) = 245 g
