You have three drinks in front of you. You know how they were made, but are unsure
which one has the highest concentration of juice crystals. The first drink has 10 g of juice crystals dissolved in
50 mL of water. The second drink has 15 g of juice crystals dissolved in 100 mL of water. The third drink has 6 g
of juice crystals dissolved in 25 mL of water.
What was the most concentrated drink? How did you determine this since all three drinks had different
amounts of solvent?

Answers

Answer 1

Answer:

.

Explanation:

Answer 2
I would say that the third one(6 h with 25mL) has the most because when the mL are multiplied to equal the other the grams of crystals will be more than the original grams. For example is you would multiply 25mL of water and 6g of juice crystals by two the mL would be equal for the first equation however the crystals from the third equation will be more. Also if you multiply 25mL of water and 6g of juice crystals by four to equal the second equation the water would be equal however the crystals in the third equation will be more.

When the air inside a school gets warmer (temperature increases), the molecules of air move faster and farther apart. True Or False?

Answers

Answer: The answer is false

Answer:

The answer is False

Explanation:

If you want a visual representation, take water. When its left at room temperature the molecules are moving but not very fast. If you bring that water to a boil, the molecules move a lot faster and get closes together. If you were to freeze that water inside a closed container you would see the water inside expand because the molecules grow further apart.

To answer the question, while the molecules do move faster, they do not move further apart.

Answers

Answer:

The 2nd juice is more concentrated.

Explanation:

To find out the answer of this question we have to find the ratio in the juices. Such as in this case :

The 1st drink=10/50=0.2

The 2nd drink=15/25=0.6

It is quite clear to us from this ratio that the 2nd drink is more concentrated than the 1st one.
