Weathering is the process of breaking large rocks and boulders into much smaller ones. Weathering can be brought about by wind and water mostly. Sometimes even biological forces account for some types of weathering.
Answer:
Epsom salt is magnesium sulfate.
Answer:
The equilibrium constant is Kc
Explanation:
The equation for the formation of
can also be defined as

Now the formation constant is mathematically represented as
for the formation of 
Substituting parameters
![Kf = \frac{[AgCl_2^-]}{[Ag^+ ] * [2Cl^-]}](https://tex.z-dn.net/?f=Kf%20%3D%20%5Cfrac%7B%5BAgCl_2%5E-%5D%7D%7B%5BAg%5E%2B%20%5D%20%2A%20%5B2Cl%5E-%5D%7D)
Now the value of 
The solubility product is mathematically represented as

For
![Ksp = [Ag^+] [Cl ^-]](https://tex.z-dn.net/?f=Ksp%20%3D%20%5BAg%5E%2B%5D%20%5BCl%20%5E-%5D)
The value is given as 
The equation given to us in this question is

The equilibrium constant is mathematically represented as

For the above equation
![Kc = \frac{[AgCl^-_2]}{[Cl^-]}](https://tex.z-dn.net/?f=Kc%20%3D%20%5Cfrac%7B%5BAgCl%5E-_2%5D%7D%7B%5BCl%5E-%5D%7D)
Now
![Ksp \cdot Kf = \frac{[AgCl_2^-]}{[Ag^+ ] * [2Cl^-]}[Ag^+] [Cl ^-]](https://tex.z-dn.net/?f=Ksp%20%5Ccdot%20Kf%20%3D%20%20%5Cfrac%7B%5BAgCl_2%5E-%5D%7D%7B%5BAg%5E%2B%20%5D%20%2A%20%5B2Cl%5E-%5D%7D%5BAg%5E%2B%5D%20%5BCl%20%5E-%5D)
![=\frac{[AgCl^-_2]}{[Cl^-]}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5BAgCl%5E-_2%5D%7D%7B%5BCl%5E-%5D%7D)

Substituting values
Therefore 
Kc
3Mg + 2H3(PO4) —> Mg3(PO4)2 + 3H2

Answer:
2.5 moles HCl = 2.5moles x 36g/mole HCl = 90 grams HCl.
Explanation:
From equation ratios the reaction ratio is 1 mole Mg to 2 moles HCl. That is, given 1.25 moles Mg, moles HCl consumed will be 2(1.25)moles, or 2.5 moles HCl = 2.5moles x 36g/mole HCl = 90 grams HCl.
