Consider the densities of the liquid substances listed. a) How will substance X, a solid, with density of 0.87 g/cm^3, behave when placed in each of the other pure liquids? b) Sketch and label a test tube containing substances A,B,C, and X. Assume that the liquids do not mix or react with each other and that solid Substance X does not react with any of the liquids.

(Liquid Substances; Density; Does Substance X float or sink?)
A; 0.75;??
B;1.1;??
C;0.96;??

sinks in A, floats in B, Floats in C

To determine how substance X will behave when placed in each of the other pure liquids, you need to compare the density of substance X with the density of the liquids.

a) To determine if substance X will float or sink in each liquid, compare the density of substance X with the density of the liquid. If the density of substance X is higher than the density of the liquid, it will sink. If the density of substance X is lower than the density of the liquid, it will float. Here are the comparisons:

- Substance X (density 0.87 g/cm^3) vs Substance A (density 0.75 g/cm^3): Since the density of substance X (0.87 g/cm^3) is higher than the density of substance A (0.75 g/cm^3), substance X will sink in substance A.
- Substance X (density 0.87 g/cm^3) vs Substance B (density 1.1 g/cm^3): Since the density of substance X (0.87 g/cm^3) is lower than the density of substance B (1.1 g/cm^3), substance X will float in substance B.
- Substance X (density 0.87 g/cm^3) vs Substance C (density 0.96 g/cm^3): Since the density of substance X (0.87 g/cm^3) is lower than the density of substance C (0.96 g/cm^3), substance X will float in substance C.

b) To sketch and label a test tube containing substances A, B, C, and X, you can draw a vertical test tube and place the liquids inside it. Label each substance accordingly. Make sure to arrange them according to their density, with the heaviest liquid at the bottom and the lightest liquid at the top. Substance X (solid) should be placed in the test tube above the liquid where it would float. Here's an example:

_____
| |
| | Substance X
| |
|_____| Substance B
| |
| | Substance C
|_____| Substance A

Remember, this configuration assumes the liquids do not mix or react with each other, and substance X does not react with any of the liquids.
