Answer:
Liquids and gases.
For most substances, when heated to a high enough temperature, the molecules begin moving faster which results in its liquid or gas state.
The formula for the compounds in the reaction are as follows with the respective states
Carbon monoxide - CO (g)
hydrogen - H₂ (g)
methane - CH₄(g)
water - H₂O (l)
reaction of carbon monoxide with hydrogen gas gives rise to methane and water
the balanced chemical equation for the above reaction is as follows
CO(g) + 3H₂(g) --> CH₄(g) + H₂O(l)
A. They speed up chemical reactions
Answer: the gas molecules interact with one another
