Explain why the formula hci can represent two different chemical systems.

Explanation:

HCl is formed by the covalent bond between the hydrogen and the chlorine atom.

It represents two different chemical systems as:

In gaseous phase, it is hydrogen chloride gas which is a pungent smelling gas.

In aqueous medium , when it is dissolved in acid, it behaves as strong acid which if concentrated, can cause severe burns and hazards.

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.

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
