Answer : The concentration of silver ion is, 
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of 
will be,
![K_{eq}=[Ag^+]^2[S^{2-}]](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5BAg%5E%2B%5D%5E2%5BS%5E%7B2-%7D%5D)
![2.4\times 10^{-4}=(2.5\times 110^{-1})^2[S^{2-}]](https://tex.z-dn.net/?f=2.4%5Ctimes%2010%5E%7B-4%7D%3D%282.5%5Ctimes%20110%5E%7B-1%7D%29%5E2%5BS%5E%7B2-%7D%5D)
![[S^{2-}]=3.8\times 10^{-3}M](https://tex.z-dn.net/?f=%5BS%5E%7B2-%7D%5D%3D3.8%5Ctimes%2010%5E%7B-3%7DM)
Therefore, the concentration of silver ion is,
Answer:
i not sure but i searched it up and it said Q=104525J
Explanation:
Answer:
Assuming that all of the oxygen is used up, 1.53×4111.53×411 or 0.556 moles of C2H3Br3 are required. Because there are only 0.286 moles of C2H3Br3 available, C2H3Br3 is the limiting reagent.
Limiting Reagent What is the limiting reagent if 76.4 grams of C2H3Br3 were reacted with 49.1 grams of O2? C2H3Br3 + 11O2 → 8CO2 + 6H2O + 6Br2 SOLUTION Using Approach 1: A. 76.4g × (1 mol/ 266.72 g) = 0.286 moles C2H3Br3 49.1g × (1 mole/ 32 g) = 1.53 moles O2 B.

Answer:
Density is a word we use to describe how much space an object or substance takes up (its volume) in relation to the amount of matter in that object or substance (its mass). Another way to put it is that density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density.
Explanation:
Answer:
A
Explanation:
I believe the answer is A. An object is every color except the color we see, or the color that bounces off of said object. Therefore if a carpet is yellow, the carpet is every color but yellow. Yellow is the color that it rejects, bounces off of it, and the one we see.
