Dipole molecules, those having a negatively charged pole and a positively charged pole, if they are in a liquid medium such as an aqueous solution, will orient themselves according to Coulomb's Law, with negative poles close to positive poles and distant from other negative poles.

What happens when polar molecules are between oppositely charged metal plates?
When polar molecules are placed between oppositely charged metal plates they will align themselves. They align in the direction of the field.
The OH bonds in water molecule are polar. The molecule is symmetric and the HOH bond angle is approximately 107 degree. The dipole moment vector of the molecule is?
From a physical standpoint, the dipole moment vector of a molecule is the net electric static force between the atoms. Assuming the molecule to be symmetrical, the vectors from the hydrogens toward the oxygen will cancel in the x-direction, leaving only a vector going from the center of the two hydrogens toward the oxygen.
Force of attraction between nonpolar molecules?
Two non polar molecules will be attracted to each other by dispersion forces (van der Waal forces).
Does high viscosity have strong intermolecular forces?
Viscosity is a measure of resistance of a fluid t flow. When a fluid flows, a portion of it moves with respect to the neighboring portions. Since there are cohesive forces between the molecules of that liquid, like intermolecular forces, these forces create an "internal friction" which reduces the rate of flow of that fluid, so when a substance has greater IMF, these frictional forces are stronger. Therefore, it has more resistance toward moving.
ATP is produced by substrate level ATP synthesis and by?
There are multiple chemical pathways toward the synthesis of adenosine triphosphate (ATP) molecules. The second, and answer to this question is anaerobic respiration, such as the lactic acid cycle.
What mineral is known to orient itself toward magnetic north?
magnetite

Does lathering with soap get what you're cleaning cleaner than if you don't lather up?
Yes. Lathering generates more bubbles. The bubbles make you cleaner. Soap has a surfactant that is amphipathic, one end is water soluble, the other is not. The end that is not water soluble clings to things like dirt and oils. These then orient themselves inside the bubble because they do not like water, the ends that are water soluble orient themselves toward the water
Why do Muslims orient themselves toward the Kaaba when they pray?
Muslims orient themselves toward the Kaaba in Mecca when praying because it is considered the holiest site in Islam. The act of facing the Kaaba during prayer symbolizes unity and solidarity among the Muslim community, as all Muslims around the world face the same direction when they pray. It also serves as a physical focal point to help Muslims concentrate and feel a connection with the Prophet Ibrahim (Abraham) and the origins of Islam.
What is dipole dipole interation?
It is a type of attraction between the positive end of a polar molecule and the negative end of another polar molecule.Molecules like HCl are made up of elements with vastly different electronegativities, Chlorine being extremely electronegative and Hydrogen being much, much less electronegative. Highly electronegative elements like Chlorine pull electrons shared in their covalent bonds much harder toward their nucleus and away from the other atom's. This means that the electron (which is negatively charged) will be closer to the Chlorine atom than the Hydrogen atom, creating a negative charge on the Chlorine side of the molecule and a positive charge on the Hydrogen side, making HCl a polar molecule. When near other polar molecules, the positive hydrogen side will attracted to their negative ends and the negative Chlorine side will be attracted to their positive ends, which is a dipole interaction
What are two main particales that make up the cell membrane?
The cell has a phospholipid membrane with other molecules interspersed throughout. However, phospholipid is the major player. It is a molecule with a lipid (fat) tail and a phosphate head. The molecules orient themselves, due to hydrophobic interactions so that there is a double row of phosphate with tails of lipid facing toward each other. This allows the membrane to interact with both the cellular and extracellular space, which are both watery, and provide some regulation for what enters and exits the cell.
What are some attitudes of workers toward themselves in office work?

What pulls molecules in the air toward earth?
gravity
Where do free water molecules move toward?

How does hydrophobic and hydrophilic behaves in water?
hydrophilic substances are electrically polar in character, they possess a dipole. Intermolecular forces associated with this polarity attract (or are attracted by) the polar water molecules. Having sufficient energy, the water molecules can interpose themselves between and eventually surround the hydrophilic substance thus reducing the repulsive intermolecular forces acting between these hydrophilic molecules in their pure state... Energy and Entropy effects are driving the process...
What pulls gas molecules in the atmosphere toward the Earth?
gravity
How does electronegativity affect the of the bond between two atoms?
The more electronegative an atom is the more "pull" the atom will have on the electrons in the molecules. For example, water (H2O) contains the very electronegative atom Oxygen. Oxygen would pull more electrons toward it so the hydrogen would essentially lose their electrons. The dipole moment would point towards the oxygen. Therefore, the more electronegative an atom is the more the dipole moment will point in its direction therefore affecting polarity of the bond.
