What is an orderly three dimensional arrangement formed by ion?
molecules
Different shape between organic and inorganic material?
the inorganic is a water molecules or up down
What statement concerning the water molecule in the equation is true?
It is spilt and becomes part of the product molecules
What is the relationship between surface area and dissolution rate?
In general, the dissolution rate is directly proportional to surface area. This is because the surface area tells you how much solute is exposed to the solvent. The greater the surface area, the more solute molecules that can bind to the solvent molecules, which means more dissolution.
What are the 4 general types of molecular geometry?
There are six basic shape types for moleculesLinear: In a linear model, atoms are connected in a straight line. The bond angles are set at 180°. A bond angle is very simply the geometric angle between two adjacent bonds. For example, carbon dioxide and nitric oxide have a linear molecular shape.Trigonal planar: Just from its name, it can easily be said that molecules with the trigonal planar shape are somewhat triangular and in one plane (meaning a flat surface). Consequently, the bond angles are set at 120°. An example of this is boron trifluoride.Bent: Bent or angular molecules have a non-linear shape. A good example is water, or H2O, which has an angle of about 105°. A water molecule has two pairs of bonded electrons and two unshared lone pairs.Tetrahedral: Tetra-signifies four, and -hedral relates to a surface, so tetrahedral almost literally means "four surfaces." This is when there are four bonds all on one central atom, with no extra unshared electron pairs. In accordance with the VSEPR (valence-shell electron pair repulsion theory), the bond angles between the electron bonds are arccos(−1/3) = 109.47°. An example of atetrahedralmolecule is methane (CH4).Octahedral: Octa-signifies eight, and -hedral relates to a surface, so octahedral almost literally means "eight surfaces." The bond angle is 90 degrees. An example of an octahedral molecule issulfur hexafluoride (SF6).Pyramidal:Pyramidal-shaped molecules have pyramid-like shapes. Unlike the linear and trigonal planar shapes but similar to the tetrahedral orientation, pyramidal shapes requires three dimensions in order to fully separate the electrons. Here, there are only three pairs of bonded electrons, leaving one unshared lone pair. Lone pair - bond pair repulsions change the angle from the tetrahedral angle to a slightly lower value. An example is NH3 (ammonia).
What geometries tend to be present in polar molecules?
Trigonal planar and tetrahedrral geometries tend to be present in polar molecules.
What are pathogen-associated molecular patterns?
Pathogen-associated molecular patterns are a set of class-specific molecules constitutively expressed in pathogens. They may be made of proteins, carbohydrates, lipids and/or nucleic acid. They may be located inside of outside the pathogen.
If the yellow molecules have a molecular mass of 25 amu what is the molecular mass of the blue molecules?
Without additional information, it is impossible to determine the molecular mass of the blue molecules based solely on the molecular mass of the yellow molecules. Each type of molecule has its own unique molecular mass, and it cannot be inferred from other molecules.
A theory that predicts some molecular shapes based on the idea that pairs of valence electrons surrounding an atom repel each other?
VSEPR theory predicts molecular shapes by considering the electron pairs in the outer shell of an atom and their repulsions. It suggests that electron pairs arrange themselves to minimize repulsion, leading to specific molecular geometries. The theory is helpful in understanding the shapes of molecules and predicting their properties.
What are the molecular units of fat molecules?
Fatty acid molecules and glycerol molecules.
What are molecules with the same molecular formula but different molecular shape?
Isomers
What is included in a molecular formula?
Molecules
What does molecular?
Adjective- Referring to molecules
What is molecular physics?
Molecular physics is a branch of physics that studies the physical properties and behavior of molecules. It explores how atoms are bonded together to form molecules, their internal structure, and the interactions between molecules. Molecular physics plays a crucial role in understanding chemical reactions, materials science, and biological processes at a molecular level.
What is molecular space?
Molecular Spacing, is the space between molecules in an atom. :D
What is the basis of molecular sieve chromatography?
The purification in molecular sieve chromatography is dependent on the size of the molecules. The small molecules will enter into pores of gel while large molecules will be excluded from the pores.
Why is it that only molecular compounds can have a molecular formula?
Because there are no compounds that aren't molecules/molecular. The question as posed is nonsense. Rephrase?
