(I know this is totally irrelevant but hardly anyone is on Chemistry) Write a chemical equation for the combustion of each of the following substances. If a compound contains carbon and hydrogen, assume that carbon dioxide gas and liquid water are produced. (Use the lowest possible whole number coefficients. Include states-of-matter under the given conditions in your answer.) (a) solid barium

    In elemental states, you're looking at reactions like these:\[\rm C~(s) + O_2~(g) \longrightarrow CO_2~(g) \]\[\rm Na + O_2 \longrightarrow Na_2 O \]\[\rm N + O_2 \longrightarrow NO_2\]

    Why \(\rm Ba_2 O \)? Why not \(\rm Ba_2 O_3\) or \(\rm BaO_2\) or \(\rm BaO\)?

    Since Ba has a +2 charge and O has a -2 charge

    So for my other questions do I just add \[O _{2}\]

    I think my teacher didn't cover this too thoroughly and he moves from subect to subject pretty quickly as well
