Two aqueous sulfuric solutions containing 20.0 wt % h, sos (sg 1.139) and 60wt % h, so , ( sg 1.498) are mixed to form a 4.0 molar solution (sg 1.213) a. calculate the mass fraction of sulfuric acid in the product solution b. taking 200 kg of the 20 % feed solution as a basis, draw and label a flowchart of this process, labeling both masses and volumes. do degree of freedom analysis: c. viii, how many unknowns? ix. how many balances can be subtracted? x. how many specific gravities can be subtracted? xi. what is the result? d. calculate the feed ratio (liters 20% solution/liter 60 % solution) what feed rate of the 60% solution (l/h) would be required to produce 2000 kg/h of e. the product

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.
