In 1897, Joseph Thomson discovered that atoms contained electrons. He proposed a change in the atomic theory of that time, and t

he theory was modified because of his discovery. Since Thomson's discovery, atomic theory has been further modified. What is the best explanation for why scientific theories are modified?

Answer:

because it is a theory

Explanation:

The best explanation for why scientific theories are modified is simply because it is a theory. Theories are created as a set of suppositions that help humanity understand something that would otherwise be unexplainable. Since they are not proven through scientific facts but instead are more of ideas that help further our understanding of a phenomenon, they tend to be modified as new ideas are introduced and others are proven to be false/wrong.

_________ is a systematic method of naming chemical compounds. This creates an unambiguous and consistent name for any chemical
Vlada [557]

Answer: IUPAC NOMENCLATURE

Explanation:

IUPAC stands for International Union of Pure and Applied Chemistry. They devised a systematic method for naming compounds in order to create a uniform global unambiguous system of nomenclature hence making it easier for researchers to share information more freely without the hindrance of reporting the same compound using different names in different parts of the world thus creating confusion in chemical literature.

Please help<br> Explain why a molecule that has polar bonds can be a polar molecule.
Zepler [3.9K]

Answer:

Explanation:

Well, obviously a molecule with polar bonds can be polar in itself. It's like saying I am an atheltic person who can just reach the basketball rim with my head and also I can dunk.

But if the question is how can a molecule that in non-polar have polar bonds, well, its because the polar bonds' dipole cancels each other out. It's like a tight rope. If a person pulls in one direction, it intuitively, the rope would go in that direction. However, if a person pulls in the other direction with the same amount of force, the rope stays still. This is the same case. Although molecules can have different electronegativities, the pull of electrons in one direction is cancelled out by a pull in the opposite direction, making the net dipole 0.

This is common for main VSERP shaped molecules like linear, trigonal planar, tetrahedral, trigonal bipyramidal, and octahedral.
