A) if the equilibrium concentration in the reaction 2no2 ⇌ n2o4 finds [n2o4]= 2.9x10-3 and [no2]= 4.2x10-3 find the equilibrium constant, k.
b) given k, if 0.100 m of no2 reacts, what will be the concentraitions when the reaction gets to equilibrium?
c) if to the equilibrium, from previous, we add 0.0500 m n2o4, calculate the equilibrium concentraitions. which direction did the reaction shift?

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. 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.

you gotta add the following molecules so we can give u an answer
