What methods can you take locally to reduce the strain on the water supply in your community if measures like water restrictions are put in place?

a. they are both space stations

happy to

pls mark as brainliest.

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

the answer your looking for is c).
