How does weathering change rock and minerals
Phantasy [73]

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.

Calculate the value of the equilibrium constant, K c , for the reaction AgCl ( s ) + Cl − ( aq ) − ⇀ ↽ − AgCl − 2 ( aq ) K c = ?
Luda [366]

Answer:

The equilibrium constant is  Kc =1.9116*10^{-5}  

Explanation:

      The equation for the formation of AgCl_2^- can also be defined as  

                  Ag^+(aq) + 2Cl^-(aq) -----> AgCl^-_2(aq)

Now the formation constant is mathematically represented as

            Kf =\frac{concentration \ of \ formation \ionic\ product }{concentration \ of \ formation \ionic \ reactant }     for the formation of AgCl_2^-

Substituting parameters

                Kf = \frac{[AgCl_2^-]}{[Ag^+ ] * [2Cl^-]}

Now the value of  Kf = 1.8*10^5

    The solubility product is mathematically represented as

                    Ksp = The \ product \ of  \  the concentration  \ of \ the \ reactant

For AgCl

                   Ksp = [Ag^+] [Cl ^-]

The value is given as Ksp = 1.77*10^{-10}

The equation given to us in this question is

              AgCl ( s ) + Cl ^- ( aq ) -----> AgCl ^-_ 2 ( aq )

The equilibrium constant is mathematically represented as

                  Kc =\frac{concentration \ of \ ionic \ product }{concentration \ of \ ionic \ reactant }

For the above equation

                  Kc = \frac{[AgCl^-_2]}{[Cl^-]}

Now

        Ksp \cdot Kf =  \frac{[AgCl_2^-]}{[Ag^+ ] * [2Cl^-]}[Ag^+] [Cl ^-]

                         =\frac{[AgCl^-_2]}{[Cl^-]}

                         = Kc

Substituting values

Therefore Kc = 1.77*10^{-10} * 1.08*10^{5}

                     Kc =1.9116*10^{-5}

Moles to grams
Evgen [1.6K]

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.
