A watershed is the area of land where all of the water drains off and eventually combines at a central point. As water runs off it picks up different types of surface pollution left over from agricultural, industrial, commercial, and other types of human activity. Why does the pollution in a watershed have such a heavy impact on its inhabitants? the species that inhabit the watershed need pollution in order to survive

pollution does not affect the inhabitants of a watershed

as the water runs towards its central point, it picks up more pollution and becomes more concentrated

that's what i got you can count the number of atoms

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

the answer is c.the valence of the atoms combine .

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
