3. Many common foods are toxic if used improperly. One example is nutmeg, yeah that stuff you use at Christmas. Nutmeg contains myristicin, an oil that can cause hallucinations, drowsiness, dizziness, confusion, and seizures. Nutmeg powder contains 30.0 mg of myristicin per 1.00 g
of nutmeg powder. The effective dose in humans is 5.00 mg per kg body mass. The average 2-year-old child is 12.90 kg. If one ounce is defined
as exactly 28.350 g, how many ounces of nutmeg would poison a 2-year-old child?

the dissolution of polymer can be thermodynamically described in 2 steps.

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.
