What is a chelating agent?

Chelation is a type of bonding of ions and molecules to metal ions. It involves the formation or presence of two or more separate coordinate bonds between a polydentate ligand and a single central atom. These ligands are called chelants, chelators, chelating agents, or sequestering agents.

Chemical compound that react with metal ions. They can form several covalent bonds to a metal without changing its own structure.

Explanation:

There's a list of chelating agents you can find in your book probably. An application of chelating agents is to transport metal ions across the membranes.

you should also know:

Chelating agents are any compound that reacts with a metal ion to produce a metal ion.

Ligand ion molecule or functional group that binds to another chemical to make a larger complex.

They are used to detoxify poisonous metal agents by binding and converting them so the body can excrete them without further harm.

the answer is definitely c.

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
