ILL GIVE BRAINLIEST HELP ASAP A watershed, also known as a drainage basin, is an area of land where the water drains to a central point like a lake, river, or an ocean. Natural vegetation in the landscape, helps maintain the natural flow regime of water and rapid changes in water levels in lakes and wetlands. Imagine a portion of a wetland that has changed as seen in the image . Predict what will happen to the natural flow of water as natural vegetation is replaced by impervious surfaces.

Groundwater flow will increase to its end point causing flooding.

Runoff will increase and less water will penetrate the soil to become groundwater.

Ground water will puddle up and remain in one place instead of flowing to a central point.

Impervious surfaces such as roads and parking lots will divert water flow and it will not reach its end point.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

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.

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
