Answer from: zuleidysnegron

The metal ion that can most adequately exist in the form of 8-coordinate complex would be:

d). U⁴⁺

'Coordination Complex' is characterized as either an ion or a compound that consists of the main metallic atom that is linked through interrelated bonds employing a fixed number of nearby encircling atoms.In the given question, the metal ion U⁴⁺ would most adequately retain in the form of 8 coordinate complexes because it allows metals to sustain in a greater rate of oxidation having a greater ratio of M:F. Since hard bases are defined by stronger acids, U⁴⁺ would be most appropriate as it is a hard acid while F⁻ is a strong base which makes it reliable.

Thus, option d is the correct answer.

Answer from: mjwaple57

U⁴⁺

Explanation:

Fluorine stabilizes metals in higher oxidation states with high M:F ratios.

Hard acids prefer to bind to hard bases.

U⁴⁺ is the hardest acid in the list and F⁻ is a hard base, so an eight-coordinate complex of U⁴⁺ is the most stable.

Answer from: Quest

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

Answer from: Quest

The correct answer would be b) volume versus temperature, because they are also directly proportional.
