Write a balanced equation using the correct formulas and include conditions (s,l,g or aq) for each of the following reactions.

1)Carbon monoxide gas reacts oxygen gas to produce carbon dioxide gas.
Express your answer as a chemical equation. Identify all of the phases in your answer.

2)Aluminum metal reacts with solid sulfur to produce solid aluminum(III) sulfide.
Express your answer as a chemical equation. Identify all of the phases in your answer.

3)In the Apollo lunar module, hydrazine gas, N2H4, reacts with dinitrogen tetroxide gas to produce gaseous nitrogen and water vapor.
Express your answer as a chemical equation. Identify all of the phases in your answer.

This is something you need to suffer through the mental processes. Do so, and I will critique it for you, repost.

I answered questions 2 and 3 on my own but still can not get number 1.

This is what I got: CO(g)+ O(g)->CO2(g)??

1) The balanced equation for the reaction between carbon monoxide gas and oxygen gas to produce carbon dioxide gas is:

2CO(g) + O2(g) --> 2CO2(g)

2) The balanced equation for the reaction between aluminum metal and solid sulfur to produce solid aluminum(III) sulfide is:

2Al(s) + 3S(s) --> Al2S3(s)

3) The balanced equation for the reaction between hydrazine gas (N2H4) and dinitrogen tetroxide gas (N2O4) to produce gaseous nitrogen and water vapor is:

N2H4(g) + N2O4(g) --> 3N2(g) + 4H2O(g)

1) To write a balanced equation for the reaction between carbon monoxide gas and oxygen gas, we need to know the chemical formulas for carbon monoxide (CO) and oxygen (O2).

The balanced equation is:
2CO(g) + O2(g) → 2CO2(g)

2) To write a balanced equation for the reaction between aluminum metal and solid sulfur, we need to know the chemical formula for aluminum (Al) and sulfur (S).

The balanced equation is:
2Al(s) + 3S(s) → Al2S3(s)

3) To write a balanced equation for the reaction between hydrazine gas and dinitrogen tetroxide gas, we need to know the chemical formula for hydrazine (N2H4) and dinitrogen tetroxide (N2O4).

The balanced equation is:
N2H4(g) + N2O4(g) → 3N2(g) + 4H2O(g)
