Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.
Answer:
The air that we breathe in enters the nose or mouth, flows through the throat (pharynx) and voice box (larynx) and enters the windpipe (trachea). The trachea divides into two hollow tubes called bronchi

Answer:
5.89 g × 10⁶ μg
Explanation:
Step 1: Convert 5.00 scruples to grains
We will use the conversion factor 1 scruple = 20 grains.
5.00 scruple × 20 grain/1 scruple = 100 grain
Step 2: Convert 100 grains to ounces
We will use the conversion factor 1 oz = 480 grains.
100 grain × 1 oz/480 grain = 0.208 oz
Step 3: Convert 0.208 oz to grams
We will use the conversion factor 1 oz = 28.34 g.
0.208 oz × 28.34 g/1 oz = 5.89 g
Step 4: Convert 5.89 g to micrograms
We will use the conversion factor 1 g = 10⁶ μg.
5.89 g × 10⁶ μg/1 g = 5.89 g × 10⁶ μg
Answer:
3.75 g/mL
Explanation:
Density can be calculated using the following formula:
Density = mass (g) / volume (mL)
You have been given the mass of the mineral sample (75 g). To find the volume, you need to determine the amount of space that the sample takes up when it is placed in the water. This can be done by subtracting the initial water volume from the final water volume.
Volume = Final - Initial
Volume = 40 mL - 20 mL
Volume = 20 mL
Now, you can calculate the density of the mineral sample.
Density = mass / volume
Density = 75 g / 20 mL
Density = 3.75 g/mL
