Answer:
K3PO4
Explanation:
Recall that colligative properties depends on the number of particles present. The greater the number of particles present, the greater the degree of colligative properties of the solution. Let us look at each option individually;
SrCr2O7-------> Sr^2+ + Cr2O7^2- ( 2 particles)
C4H11N (not ionic in nature hence it can not dissociate into ions)
K3PO4-------> 3K^+ + PO4^3- (4 particles)
Rb2CO3-------> 2Rb^+ + CO3^2- (3 particles)
Hence K3PO4 has the greatest number of particles and will display the greatest colligative effect.
Answer:
Helium has atomic mass 4.002602.
So the answer to yr question is helium.
Answer: Pigment.
Explanation: Our hair color is determined by two types of pigment, Eumelanins, and Pheomelanins. Which together produces all the natural hair colors we see every day with other people.
Reducing the volume of contained gas by one third, while holding temperature constant, causes pressure to D. be increased by one third
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.
