Sagot :
You will get at first carbon dioxide by burning C:
[tex]C+O_2=CO_2[/tex]
Burn hydrogen to obtain water:
[tex]H_2+\frac{1}{2}O_2=H_2O[/tex]
Combine them:
[tex]CO_2+H_2O=H_2CO_3[/tex]
Now react it with Ba:
[tex]Ba+H_2CO_3=BaCO_3+H_2[/tex]
To sum up, the reaction is [tex]Ba+C+\frac{3}{2}O_2=BaCO_3[/tex], using hydrogen as a catalyst.
[tex]C+O_2=CO_2[/tex]
Burn hydrogen to obtain water:
