What is the concentration of silver ions where silver iodide, Agl, is in a solution of hydroiodic

Chemistry

Answer:

[Ag^+]=2.82x10^{-4}M

Explanation:

Hello there!

In this case, for the ionization of silver iodide we have:

AgI(s)\rightleftharpoons Ag^+(aq)+I^-(aq)\\\\Ksp=[Ag^+][I^-]

Now, since we have the effect of iodide ions from the HI, it is possible to compute that concentration as that of the hydrogen ions equals that of the iodide ones:

[I^-]=[H^+]=10^{-3.55}=2.82x10^{-4}M

Now, we can set up the equilibrium expression as shown below:

Ksp=8.51x10^{-17}=(x)(x+2.82x10^{-4})

Thus, by solving for x which stands for the concentration of both silver and iodide ions at equilibrium, we have:

x=[Ag^+]=2.82x10^{-4}M

Best regards!

Explain the difference between a physical property and a chemical property
Eduardwww [97]
Physical property-  is an aspect of matter that can be observed or measured without touching changing it.

Chemical property- may only be observed by changing the chemical identity of a substance.

The difference would be that for physical property's you dont need to do anything to figure out what they are, but for chemical properties you need to change something to observe them.

How much heat is required to change temperature of 2g of water from 34°C to 68°C? (Water has a specific heat of 4.18)
statuscvo [17]

Answer: B

Explanation:

To find the amount of heat required, you would use q=mcΔT.

q=2g(4.18J/g°C)(68-34°C)

q=284.2 J

*Please ignore the capital A in the equation. I can't find a way to type in the degree sign into the equation without the A appearing.
