Specify the number of possible isomers of nitrobenzoic acid. Write the name of one of these isomers. Abbreviate ortho (o), meta (m) and para (p), no italics, if you elect to use these terms. Specify the number of possible isomers of aromatic compounds with the formula C7H8O. Write the name of one of these isomers. Abbreviate ortho (o), meta (m) and para (p), no italics, if you elect to use these terms.

3,meta, ortho,  and para-nitrobenzoic acid, when the nitro group is 1, 2, or 3 carbons away from the carboxyl on the benzene ring

There are 3 dinitrobenzenes, o-dinitrobenzene, m-dinitrobenzene, and p-dinitrobenzene.

1st is benzyl alcohol, the second is anisol.Three more are o-methylphenol, m-methylphenol, and p-methylphenol which contain a linear formula

Explanation:

catya that's not even a b or c

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
