Which equation represents an equilibrium system?

c o 2, solid, in equilibrium with c o 2, gas.

2 s o 2, gas, plus o 2, gas, in equilibrium with 2 s o 3, gas.

ag+(aq) + cl–(aq) → agcl(s)

2mg(s) + o2(g) → 2mgo(s)

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

explanation:

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
