What in VSEPR theory?
VSEPR stands for Valence Shell Electron Pair Repulsion, and it describes how valence (bonding) electrons are arranged around an atom, and how they are used in creating a bond. This then can be used to help predict the GEOMETRIC SHAPE of the molecule being formed.
Would the big bang theory help explain the shift?
I presume the question refers to the "redshift" of distant galaxies. Actually it is the other way around - i.e. the Doppler redshift helps to support and explain the Big Bang Theory. This "redshift" is called the "cosmological redshift". Strictly speaking, it's not the Doppler effect.
How did quantum mechanics change our understanding of atoms?
Quantum mechanics explained principles like superposition of wave-particle duality of mater. It shaped a world where the classical laws of physics were merely a waste. It exposed to us a world of particles, that matter was made of many groups of particles each accomplishing a particular task just like our organs. With the help of quantum mechanics we were able to get a 3 dimensional idea of the atom. It was able to explain the screening effect and the stark effect. It was also able to construct exact shape of orbitals and explain the formation of various types of compounds( A theory called hybridization and VSEPR and MOT came in handy thanks to quantum mechanics). It also explained the idea that atoms were composed of a lot more particles and helped predict their states nature and characteristics.
What are the three of the many possible shapes of molecules?
Without given a specific molecule there is not any way to determine the shape. Beryllium chloride consists of beryllium in the middle and a chlorine on each side, and is in the shape of a straight line.
Explain Harry Hess contribution to Plate Tectonic Theory?
Harry Hess developed the idea of sea floor spreading. Which help better prove Alfred Wegener's Continental Drift Hypothesis.

The theory of tectonic plates help to explain?
The theory of plate tectonics helps to explain how earthquakes and volcanic eruptions occur.
What does the VESPR theory help predict?
the shape of a molecule
What theory would help a microbiologist explain the basic structure of a microscopic organism?
the theory of evolution
What does the theory of plate tectonics help explain the locations of?
The theory of plate tectonics helps explain the location of earthquakes, as they frequently happen along fault lines.

How does the movement of particles in a liquid help explain the shape and volume of liquids?
They dont
How do Lewis structures help predict the shape of a melocule?
Look at double bonds and dotted valence. Double or more bonds equals a linear shape. Also... 2 bonds = linear 3 bonds = linear if dbl or trpl bonded, otherwise bent 4 bonds = triginal poly Etc.
How does VSEPR determine molecular geometry?
The VSEPR model has enabled chemists and students to describe, explain, and predict more easily the stereochemistry of chemical elements and compounds. The Lewis structure, which was primarily used to convey the appearance of molecules in the past, proved to be inadequate because there existed many exceptions to this type of diagram. The Lewis structure displayed no information about the geometry of a molecule as it did not indicate how atoms were arranged in space. The VSEPR theory has relieved chemists and students of such limitations by describing the orientation of a molecule in relation to the Pauli principle. By determining this principle affected molecular geometry, Gillespie illustrated that the repulsion interactions of all electron pairs, both shared and unshared ones, in the valence of a molecule determine its shape. This is due to the fact that electron pairs adapt an arrangement that keeps them as far apart as possible; they repel one another. glad to help grade 12 chem student
How do the positions and movements of particles in a liquide help to explain the shape and volume of the liquid?
because it nothing
What does dynamo theory help explain?
The dynamo theory helps explain how a planet or star can make its own magnetic field. William Gilbert was the first person to suggest that the Earth is a magnet in a report called de Magnete in 1600.
