Which term best describes liquid behavior under pressure?
BartSMP [9]
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 and flows at a constant volume and velocity.

Suppose a cobalt atom in the oxidation state formed a complex with two bromide anions and four ammonia molecules. Write the chem
Katena32 [7]

Complete Question:

Suppose a cobalt atom in the +3 oxidation state formed a complex with two bromide (Br-) anions and four ammonia (NH3) molecules. write the chemical formula of this complex.

Answer:

[Co(NH₃)₄]⁺Br₂

Explanation:

The cobalt atom with +3 oxidation is represented as Co⁺³, and if it's bonded to two bromide ions, and four ammonia molecules. The molecules that are bonded to the metal atom (Co) are called complexing agents.

In the representation, we first put the molecules that surround the metal atom, forming an anion with the oxidation of the metal:

[Co(NH₃)₄]⁺³

Then, the ions are put in the formula. Because there are two bromides ion, each one with 1 minus charge, only 2 plus charged will be neutralized, and the complex will be:

[Co(NH₃)₄]⁺Br₂

Compare and contrast elements and compunds
Firdavs [7]

Answer:

The similarity is that Elements and Compunds exist in stable form because of the bonds formed between their atoms. The difference is that an element is a material that consists of a single type of atom and a compound consists of two or more types of elements held together by covalent or ionic bonds.
