What are the top three sources of US electricity generation estimate overall efficiency of US electricity generation how does this compare to the efficiency of transportation

the answer is a. co2, this would be colder than the : )

explanation:

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 would be b. 6co2 + 6h2o --> c6h12o6 + 6o2

answer; 4 electrons;
