You will get at first carbon dioxide by burning C: C + O 2 = C O 2 Burn hydrogen to obtain water: H 2 + 2 1 O 2 = H 2 O Combine them: C O 2 + H 2 O = H 2 C O 3 Now react it with Ba: B a + H 2 C O 3 = B a C O 3 + H 2 To sum up, the reaction is B a + C + 2 3 O 2 = B a C O 3 , using hydrogen as a catalyst.
You will get at first carbon dioxide by burning C:
C+O_2=CO_2
Burn hydrogen to obtain water:
H_2+\frac{1}{2}O_2=H_2O
Combine them:
CO_2+H_2O=H_2CO_3
Now react it with Ba:
Ba+H_2CO_3=BaCO_3+H_2
To sum up, the reaction is Ba+C+\frac{3}{2}O_2=BaCO_3, using hydrogen as a catalyst. ;
The balanced chemical equation for the formation of BaCO₃(s) is Ba(s) + C(s) + \frac{3}{2} O₂(g) -> BaCO₃(s). This equation illustrates the combination of barium, carbon, and oxygen in their standard states. The reaction yields one mole of barium carbonate as a solid product.
