    I originally had \[2H _{7}Br \rightarrow 7H _{2}+Br _{2}\] Is that right?

    Binary = 2 components (atoms) you have 8 atoms in the molecule

    Oh, okay, I see what you mean. I was hesitant putting that. So would it just be \[H_{7}Br \rightarrow H_{2}+Br_{2}\] I didn't really understand my teacher's explanation on how to write these.

    I forgot to balance it.

    you didn't change the compound, i mean there is only one possibility in having two different atoms in a binary molecule. One of each

    \[2HBr \rightarrow H_{2} + Br_{2}\] ??? So 2 atoms because we know it ends with H_{2} + Br_{2} so then to balance it you'd have to add the 2 to the front?

    Would the states of matter be 2Hbr(s) H2(g) and Br2 (g)? How do you know something is a solid or gas? I know my teacher said that the only liquid is water, but other than that I guess. I remember O2 as a gas so I figure any single element with a 2 is a gas. How do you know what is solid?

    hm you'd have to be given a temperature as compounds have different melting points, or you can check solubility tables, this reaction (it doesn't say) but it's carried in an aqueous medium aka in water, so HBr (aq) -> H2 (g) + Br2(g)

    when something is written as solid in the products, it means it precipitated
