Question

select the correct answer from each drop - down menu. complete the sentences in these paragraphs describing the challenge of providing safe drinking water in different areas. people cant drink ocean water. however, in very dry areas near the ocean, people purify ocean water. they must use this process to obtain safe drinking water. the main substance thats dissolved in ocean water is salt, and it must be removed. salt water is classified as a mixture. this kind of mixture cant be separated by. instead, more must be used. the first ocean water purification method is based on the fact that water boils at a lower temperature. this method does not require heating. this method, has become more common in recent years. some parts of the world have contaminated water that causes diseases. contaminated water has microorganisms, and forms a mixture. this kind of mixture can be separated by.

Explanation:

Salt - water is a homogeneous mixture as the salt is uniformly dissolved in water. Homogeneous mixtures cannot be separated by simple physical means like filtration and require more complex methods such as distillation (water boils at a lower temperature than salt in distillation). Reverse - osmosis is a non - heating method that has become more common for water purification in recent years. Contaminated water with microorganisms is a heterogeneous mixture and can be separated by methods like filtration to remove the larger particles (microorganisms).

Answer:

1. homogeneous
2. filtration
3. distillation
4. reverse - osmosis
5. heterogeneous
6. filtration
