One of these substances is water, which has a density of 1.0 g/mL. You also have oil with a density of 0.92 g/mL, and ethanol with a density of 0.85 g/mL. When all 3 substances are mixed together which one is in the middle? A. Water
B. ethanol
C. oil
D. None of the above

Option C. Oil.

Explanation:

The following data were obtained from the question:

Density of water = 1 g/mL

Density of oil = 0.92 g/mL

Density of ethanol = 0.85 g/mL

If all three substances are mixed together, the one with the highest density will be at the bottom, the one with the second highest density will be at the middle while the one with the least density will be at the top.

When we arrange the substance in ascending or descending order according to their density, oil will be at the middle.

Now, we shall arrange in ascending order as shown below:

Position >>> Substance >>>> Density

Top >>>>>>> Ethanol >>>>>> 0.85 g/mL

Middle >>>> Oil >>>>>>>>>>> 0.92 g/mL

Bottom >>>> Water >>>>>>>> 1 g/mL

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
