In aqueous solution cobalt(II) ion is surrounded by 4 water molecules and has a light pink color. When high concentrations of chloride ion are introduced, a cobalt-chloride complex ion forms that has a distinctive blue color. One way to represent this equilibrium is: Cocl,"(aq) = Co2+ (aq) + 4 CI" (aq) An experiment was run to demonstrate that a dynamic equilibrium exists between these two ions. Starting with a special form of CoC142(aq) where one of the chloride ions was...

please help with all pre-lab
Dynamic Equilibrium Simulation with Pennies 1 of 11 on Equilibrium is a state where there are no observable changes over time. Equilibrium is achieved when the rate of the forward reaction equals the rate of the reverse reaction. R =P In this activity, we will simulate a reversible reaction where R = P: the reactant molecules (R) are pennies, which react and are transferred from the side to the P side, while the product molecules...

2. If the reaction between iron(III) ion and thiocyanate ion yielded an equilibrium concentration of 0.30 M for each of these ions, what is the equilibrium concentration of the red iron(III)-thiocyanate complex? (Hint: The equilibrium constant for the reaction is in the Background section.) Show your work 3. In the reaction below, NH3(g) + H2O(1) - NH; +H30+ the equilibrium constant is 10-34. Is this reaction likely to take place? Explain your answer. iron(III) and thiocyanate ions, the equilibrium expression...

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
