Answer:

This is the first answer,

winter solstice

The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually December 21 or 22) and in the Southern Hemisphere, this is the June solstice (usually June 20 or 21).

and this is the second one,

the tilt of the Earth on its axis

Seasons change because of the tilt of the Earth and the planet's movement around the Sun. Did you know? It takes about 365.25 days for the Earth to orbit the Sun. We have leap years to make up for the extra ¼ day!

What is the concentration of silver ions where silver iodide, Agl, is in a solution of hydroiodic
jonny [76]

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!

What is the economic importance of phosphorus in Canada or elsewhere in the world?
vladimir1956 [14]

white phosphorus is used in flares and explosives, so may be important in warfare, etc. Red phosphorus is used in matches (side of matches) and in fertilizers which are essential to growing plants. I don't know if that is economically important, but there are many ways that phosphorus benifit the economy. One downside on the economy is that phosphorus is one of the main ingredients in meth, which of course causes trouble for the economy ( law enforcement, medical, etc. )
