Answer:

Geocentric model

Explanation:

Aristotle was a Greek astronomer. He proposed geocentric model of the solar system. This was based on the observations from the ancient astronomers. The word planet means wandering stars as the planets appeared to be point star like bodies moving through the sky.

Geocentric model described the earth to be at the centre of the solar system with sun, other starts and planets revolving about it.

if the complex has a formula of [m(h2o)6]3 , what effect will replacing the 6 aqua ligands with 6 cl− ligands have on δ ?
Eduardwww [97]

When we replace neutral ligands with negative ligands then the value of C.Δ will decrease.

In coordination chemistry, a ligand is an ion or molecule that binds to a significant steel atom to shape coordination complicated. The bonding with the metal generally includes a formal donation of 1 or more of the ligand's electron pairs regularly through Lewis Bases.

A ligand is defined as any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. whilst a ligand binds to its respective receptor, the shape and/or interest of the ligand is altered to provoke several special styles of cellular responses.

PLEASE HELP! MAJOR GRADE!
chubhunter [2.5K]

Answer:

A, B, and C are the correct answers.

Explanation:

The reason why solid, liquid, and gas are the most common of the elements because usually in school they teach you more about those 3 elements more than plasma ( from where I am ). Also, all of these states behave differently. Liquid is a substance that flows freely but is of constant volume, having a consistency like that of water or oil. Solid is firm and stable in shape. And gas is an air like substance. I'm not sure how to explain this more, it sounded better in my head. Hope this helped though!
