The VSEPR theory allows us to determine the?
The VSEPR theory allows us to determine the molecular geometry of a molecule based on the number of electron pairs around the central atom. It helps predict the shape of molecules by minimizing electron pair repulsion. This theory is useful in understanding the spatial arrangement of atoms in molecules and their properties.
How does number of electron pairs around central atom determine its shape?
The electron pairs repel one another. The electron pairs can be in chemical bonds or be present as "lone pairs". This is the basis of VSEPR theory proposed by Gillespie and Nyholm. Who both shared the first name of Ronald! (British readers may see the humour in that )
What Can Water Not Dissolve?
While ionic compounds and polar molecules dissolve the best in water, nonpolar molecules do not. Example of a such nonpolar substance: oil. Oil forms clumps or beads in water because the nonpolar molescules are shoved together. Why? The water molecules are more attracted to each other than to the nonpolar molecules.
What is a front foot assessment?
A front foot assessment is a method used in horse care to evaluate the hoof health and conformation of a horse's front feet. It involves examining aspects such as hoof shape, balance, and signs of any issues like lameness or injuries. This assessment helps determine the overall soundness and well-being of the horse.
What is the predominant force between IBr molecules in liquid IBr?
The predominant force between IBr molecules in liquid IBr is Van der Waals forces, specifically dipole-dipole interactions and London dispersion forces. These forces are responsible for holding the IBr molecules together in the liquid state.
How are solids and liquids determine?
solids are hard the molecules are squished together and if you pour it in a glass it wont take shape. liquids will take any shape
What technology allowed Pauling and then Franklin to determine the helical shape of various biological molecules?
3 d modeling
What determine how organic molecules will look and behave?
the form determines how the organic molecule will look and the shape will determine how the behave organic molecule reacts with other molecule
What shape did Watson and Crick determine DNA molecules were?
Watson and Crick determined that DNA molecules are in the shape of a double helix, which resembles a twisted ladder. The double helix structure consists of two strands that are connected by complementary base pairs.
How is the smell of a substance related to its molecular shape?
The smell of a substance is related to its molecular shape through the interaction of odorant molecules with olfactory receptors in the nose. The specific shape and structure of the odorant molecules determine how they fit into the receptors, leading to the perception of different smells. Small changes in molecular shape can result in significant differences in odor perception.

What affects the shape of molecules?
The chemical compositon and the chemical bonds affect the shape of molecules..
How does a DNA molecule determine structures of a specific protein?
The DNA sequence will determine the amino acid sequence known as the protein's primary structure. As the protein is folded into the secondary, tertiary and quatranary structures, the amino acid molecules will determine the shape
How does DNA determine the shape and size of a cell?
DNA codes for all of the proteins in the cell. Proteins are used as many things within the cell, including signalling molecules which communicate between different parts of the cell, and enzymes, which can adjust the length of structural molecules which keep the cells shape. The shape of the cell is also determined by physical constraints such as outside pressure, the surface area/volume ration, and how fast molecules can diffuse into the centre of the cell.
What general shape do molecules have?
The general shape is "bent".
Watson and Crick determined that DNA molecules have the shape of a?
Double-helix (or spiral staircase). They used x-ray diffraction data from Rosalind Franklin to determine this.
What does the VSEPR theory tell about a molecule?
A. The geometry it will have
