Devise the most efficient synthesis for the carboxylic acid below using a starting material and reagents from the tables. give your route by specifying the number of the starting material followed by the letters of the reagents you would use beginning with the first step. the answer 4fh means treat t-butanol(4) with conc. hcl(f) then treat the product with koh in alcohol(h). starting materials reagents the most efficient synthetic route is .

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

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.
