Draw the structure of the product formed in the reaction of an epoxide with ethoxide ion. If more than one stereochemical product is possible, draw only one isomer. The starting material is a 6 carbon ring fused to an epoxide through carbons 1 and 2. Both carbons have a wedged bond to the epoxide oxygen and a dashed bond to hydrogen. Step 1 reacts with sodium ethoxide, C H 3 CH 2 O minus. Step 2 is H plus and ethanol.

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.

answer///carbon;

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
