Answer:

D. Surface tension.

Explanation:

Surface tension is defined as the energy required to increase the surface area of a liquid by a unit amount.

The surface tension of a liquid results from an imbalance of intermolecular attractive forces, the cohesive forces between molecules:

A molecule in a liquid experiences cohesive forces with other molecules in all directions while molecules at the surface of a liquid experiences only net inward cohesive forces.

What is the equilibrium constant of a reaction
Svetach [21]

Homogeneous Reactions. At equilibrium, the rate of the forward and reverse reaction are equal, which is demonstrated by the arrows. The equilibrium constant, however, gives the ratio of the units (pressure or concentration) of the products to the reactants when the reaction is at equilibrium.

Which equation represents an oxidation-reduction reaction?
bazaltina [42]
In an oxidation-reduction reaction there is an exchange of electrons.


The exchange of electrons implies change in the oxidation states: at least one element increases its oxidation number while other reduces it.


By simple ispection you can predict that in the equation b. there is a change in oxidation states of Cl and Mn.


Now you can check it:


Equation             4H   Cl     +    Mn  O2     ->    Mn  Cl2   + 2H2 O     + Cl2    

oxidation sates   1+  1-             4+   2-              2+   1-         1+   2-         0


The oxidation state of Cl in HCl is 1-  and it changed to 0 in Cl2


The oxidation state of Mn in MnO2 is 4+ and it changed to 2+ in MnCl2
