Having 2SO3(g) > 2SO2(g) + O2(g) the Kc = 3.57 x 10^-3 at 726.85 celcius degrees what is the equilibrium K for the following reaction at 726.85 celcius degrees and 0.25 mol SO3(g)> 0.25 mol SO2(g) + 0.125 mol )O2(g) answers 0.00357 2.64x10^-20 4.46 x10^-4 0.494 0.244

the answer to this question is 3.

while cooking a piece of 1/2 pound beef steak, a cast iron pan (2.4kg in weight) was heated 260 celsius.

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.
