Explanation:
Box C will have the greatest density.
All boxes have the same volume.
Explanation:
We calculate the density using the following formula:
density = mass / volume
density of Box A = 10 g / 20 cm³ = 0.5 g/cm³
density of Box B = 30 g / 20 cm³ = 1.5 g/cm³
density of Box C = 170 g / 20 cm³ = 8.5 g/cm³
Box C will have the greatest density.
All boxes have the same volume.

A chemical property is a characteristic of a substance that may be observed when it participates in a chemical reaction. Examples of chemical properties include flammability, toxicity, chemical stability, and heat of combustion
Answer:
0.013 M/s
Explanation:
Given data
- Initial concentration of BrO⁻: 0.56 M
- Final concentration of BrO⁻: 0.14 M
Since the final concentration of BrO⁻ is lower than the initial concentration of BrO⁻, BrO⁻ is dissapearing. The rate of dissapearance of BrO⁻ is:
rBrO⁻ = - Δ [BrO⁻] / t
rBrO⁻ = - (0.14 M - 0.56 M)/ 33 s
rBrO⁻ = 0.013 M/s
You need to round to 3 significant digits.
0.783 g/ml
