Which term best describes liquid behavior under pressure? The correct answer is incompressible. Liquids or fluids that behave under pressure are called incompressible fluids because they tend to behave through flowing movements. An example of an incompressible fluid is the lava which comes out of a volcano where once out of the atmosphere becomes dense

Which chemical species can form an ionic bond with an anion? Hg22+ NO2– SO32– Ar Anion has a negative charge, so will be a non metallic element. an ionic bond is formed between metal and non mental, therefore Hg2+ being both metallic and having a positive charge, is the cation required to form an ionic
