A chunk of sulfur has a volume of 8.33 cm3. What is the mass of this sulfur? (Density of sulfur = 2.07 g/cm3.)
nata0808 [166]

Explanation:

equations to note:

density= mass/volume

mass= volume *density

volume= mass/density

you have a volume- 8.33cm3

you have a density- 2.07 g/cm3

Answer:

8.33cm3 * 2.07g/cm3=  17.24g

mass= 17.24g

If an acid has a Ka of 4.3 × 10-7 and a base has a Kb of 5.6 × 10-4, then what will be true about the salt produced? A. The salt
blsea [12.9K]

If an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.

<h3>What is acid and base constant?</h3>

An acid dissociation constant, Kₐ, is a quantitative measure of the strength of an acid in solution while Kb indicates the high level of dissociation of a strong base.

According to this question, an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴. This shows that the strength of the base is higher than that of the acid.

Therefore, if an acid has a Ka of 4.3 × 10-⁷ and a base has a Kb of 5.6 × 10-⁴, then the true statement about the salt produced is that the salt would decrease the pH of the solution.
