Amena is assigned a sample mixture to separate in chemistry class. she knows it is an emulsion of oil and salt water that also contains some suspended solids. place the steps in the order that makes the most sense for separating the salt from the mixture. (1 = first, 4 = last) remove the top layer. screen the mixture through a fine mesh. centrifuge the mixture. heat the mixture to the boiling temperature of water until it evaporates completely.

Explanation:

Heat the mixture to the boiling temperature of water until it evaporates completely is good for removing water from salt. So it should be the last step (4).

Centrifuge the mixture is good for removing fine suspended solids so it should be next to last step (3).

Screen the mixture through a fine mesh will remove coarse suspected solids so It should be the second step (2).

Remove the top layer will remove the oil so it should be the first step (1).

radiative zone

explanation    

radiative zone is the layer of the sun which energy is transferred away from the core by radiation. although, the core is the only part of the sun that produces an appreciable amount of heat through fusion. in fact, 99% of the energy produced by the sun takes place within 24% of the sun's radius.
