C. Gravitational Energy doubles as mass doubles.

Explanation:

For the platypus the height is 1 and the grav. energy is 9.8

As the height doubles to 2 (for the squirrel) the gravitational energy also doubles to 19.6 (9.8*2=19.6).

Same thing for the flying squirrel (2 height),(19.6 grav. energy)

(2*2=4)    (19.6*2=39.2) ---Skunk height:4 and Skunk energy:39.2

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
