Answer 2

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

Step-by-step 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)`
