Studies indicate that acidification of the ocean by the absorption of carbon dioxide is harmful to virtually all marine life and ecosystems. the group most vulnerable to both warming and acidification would be the

the Calcifying species

Explanation: These species of organisms, like the phytoplanktons depends on calcium carbonate minerals to form hard shells. However, due to the acidification of the ocean by the addition of carbon dioxide which react with water to form carbonic acids, the carbonate minerals become inhibited thereby causing harm and slow growth rate to those species of organisms.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

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.
