What is a possible ph of acid rain?
7.0
6.9
4.3
10.5

Answer : The correct option is, 4.3

Explanation:

Acid rain : It is formed by a chemical reaction when sulfur dioxide and nitrogen oxides are released into the air.

The pH range is, 1 to 14.

When the value of pH is less than 7 then the solution is acidic.

When the value of pH is more than 7 then the solution is basic.

When the value of pH is equal to 7 then the solution is neutral.

The pH of normal clean rain in between 5.0 to 5.5 which is partially acidic.

When rain combines with sulfur dioxide and nitrogen oxides then the rain becomes more acidic and the pH of acidic rain is, 4.0

Hence, the correct option is, 4.3

coral.

explanation:

coral. many marine organisms that produce calcium carbonate shells or skeletons are negatively impacted by increasing co2 levels and decreasing ph in seawater.

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.
