Which three relationships are true at equilibrium? ecell = 0, and ∆g = 0, and q = k ecell > 0, and ∆g < 0, and q = k ecell < 0, and ∆g < 0, and q < k ecell = 0, and ∆g > 0, and q = k ecell = 0, and ∆g > 0, and q > k

The correct answer is option A. i.e. Ecell = 0, and ∆G = 0, and Q = K

Ecell is the cell potential or voltage between the two cells.
∆G is the Gibbs free energy. It is actually a difference in the energies of products and reactants.
K is the equilibrium constant for any reaction.
As you can see from the figure attached, the conditions Ecell = 0, and ∆G = 0, and Q = K favour no reaction, which means, the equilibrium is maintained.

4- c, because all matter stays the same no matter what. it is still there. 5- b, because matter is known as mass. 6-c because, flammability is a chemical property. malleability is changing the shape of an object.

The correct answer is b.hoped i you
