The correct answers to these questions on solutions, elements, and compounds are provided below:

  • 11. D. Solution
  • 12. C. Mixture
  • 13. B. Magnet
  • 14. D. Sugar and water
  • 15. D. Have constant boiling temperature and melting temperature

A solution is a sort of homogenous mixture whereby a solute is dissolved in a solvent. A mixture refers to two or more substances that are not chemically combined.

In a mixture of two substances with iron as a constituent, a magnet can be used for separation purposes.

A pure substance has just an element or compound whose boiling and melting temperature is constant.

This is unlike a mixture that boils and melts over a range of temperatures.

Conclusively, the above bullet answers are the separation techniques and states of matter.

Which sentence shows the best example of allieration
Sunny_sXe [5.5K]

Answer:

D. Lyle, lest licorice looked luckier, largely loved lollipops.

Explanation:

Alliteration is the repetition or use of the same letters of the words in any given sentence in close quarters. In simple words, it is the repetition or use of the consonant sounds in the construction of a sentence.

Among the given sentences, option D is the best example of alliteration. This is because the letter "l" is repeatedly used in the other words. The start/ beginning of the words in that sentence starts with the letter "l" which makes it a repetition of the same sound.

Thus, the correct answer is option D.

In devil's arithmetic why do the girls make their numbers mean things? What purpose does it serve for them? (Answer in 2-3 compl
kati45 [8]

Answer:

The numbers, for them, are a way to process and survive, feeling they have some kind of control over such a chaotic situation.

Explanation:

In "The Devil's Arithmetic" ( 1988), by Jane Yolen and published in 1988,  Hannah Stern and the girls that she meets while imprisoned during the Holocaust, develop a theory about the numbers they had tattoed on them as a way to identify them, to give them meaning and eve premonitory influence on their lives. The Devil's Arithmeticrefers to the idea that each person who dies instead of them, means one more day that they get to be alive and not sent to the gas chamber. However, they develop more deep explanations. Rivka, for example, says;

"The 1 is for me because I am alone. The 8 is for my family because there were eight of us when we lived in our village. And the 2 because that is all that are left now, me and Wolfe, who believes himself to be a 0. But I love him no matter what he is forced to do. And when we are free and this is over, we will be 2 again."
