Consider the chemical reaction in equilibrium. h2 + i2 + heat mc006-1.jpg 2hi what will happen to the chemical equilibrium if the temperature of the system is increased? the direction of the chemical equilibrium will shift to the right, favoring the forward reaction. the chemical equilibrium will not be affected by an increase in temperature. the direction of the chemical equilibrium will shift to the left, favoring the reverse reaction. the chemical equilibrium will be lost permanently with a change of temperature.

i think its 100

i hope this !

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.
