Hydrogen gas is used for many purposes, including the hydrogenation of vegetable oils to make margarine. The most common industrial process for producing hydrogen is "steam reforming," in which methane gas, CH4, from natural gas reacts with water vapor to form carbon monoxide gas and hydrogen gas

Write a complete balanced equation, including states, for this reaction

I balanced that Co and phosphate equation for you. What is it you don't understand about these equations? I can help do one but if you have problems we need to know how to help so you can do these yourself.

To write a complete balanced equation for the steam reforming process, we need to indicate the states of the reactants and products. Here's the balanced equation:

CH4 (g) + H2O (g) → CO (g) + 3H2 (g)

In this equation, "g" indicates that each component is a gas. The reactant methane gas (CH4) combines with water vapor (H2O) to produce carbon monoxide gas (CO) and hydrogen gas (H2). The ratio of hydrogen gas to methane gas in the balanced equation is 3:1, meaning that for every one methane molecule, three hydrogen molecules are produced.

The balanced equation for the steam reforming reaction is:

CH4 (g) + H2O (g) -> CO (g) + 3H2 (g)
