Answer 2

Answer:

$C_3H_8 (g) + 3 H_2O (g) \longrightarrow 3 CO (g) + 7 H_2 (g)$

Explanation:

Hi, as it says you have two reactants: propane gas ($C_3H_8$) and steam ($H_2O$). This reaction have two products: carbon monoxide ($CO$) and hydrogen gas ($H_2$).

All compounds in the reaction are in gas state due to the high Temperature.

The reaction equation:

$C_3H_8 (g) + H_2O (g) \longrightarrow CO (g) + H_2 (g)$

Balancing:

$C_3H_8 (g) + 3 H_2O (g) \longrightarrow 3 CO (g) + 7 H_2 (g)$
