What happens to the polarity of oxygen atoms as they transform from molecular oxygen into water molecules?
In the bond in molecular oxygen, the electrons are pulled equally towards each element, as they are the same element and so have the same electronegativity.
In water, however, the bonds are between hydrogen and oxygen. The nucleus of oxygen has eight times the charge of the nucleus of hydrogen, and so attracts the electrons more strongly than hydrogen does. It does not attract eight times as strongly as hydrogen as the extra electron shell repels the electrons in the bond more than hydrogen's nonexistent shells (its only electron is in the bond). It can therefore be said that oxygen is more electronegative than hydrogen.
As the oxygen attracts the electrons more strongly than the hydrogen, it gains a partially negative charge. Similarly, the hydrogen gains a partially positive charge.
This polarity is responsible for the interesting properties of water, including its ability to stay liquid at room temperature, its low density as a solid and its ability to climb up a narrow capillary tube without any force applied to it.

What happens to all oxygen molecules that originated from carbon dioxide in the van niel experiment?
In the van Niel experiment, the oxygen molecules that originated from carbon dioxide are released as byproducts during the process of photosynthesis. These oxygen molecules are a result of splitting water molecules to produce molecular oxygen (O2) while converting carbon dioxide into carbohydrates.
What happens to the particles of a ionic solid and a molecular solid when each mixes with water?
When an ionic solid mixes with water, the particles of the solid dissociate into separate ions, which then become solvated by the water molecules. In contrast, when a molecular solid mixes with water, the solid molecules remain intact and may dissolve or form a solution depending on the intermolecular forces between the molecules and water.
How can molecules of sugar be dissolved by molecules of water?
When crystallized sugar is put into water, the H2O molecules separate the sugar molecules from each other. This happens because both H2O and sugar molecules are polar. The polarity causes the much smaller H2O molecules to squeeze between the sugar molecules and break the weak van der Waals forces that exists between them. The H2O molecule bonds to the sugar molecule with a stronger bond than the earlier van der Waals force (because of the polarity of the molecules).
Which molecule contains non polar covalent bonds?
Nonpolar molecules are of two types. Molecules whose atoms have equal or nearly equal electronegativities have zero or very small dipole moments. A second type of nonpolar molecule has polar bonds, but the molecular geometry is symmetrical allowing the bond dipoles to cancel each other.
What happens to a solute when it dissolves in a solvent?
When a solute dissolves in a solvent, the solute particles separate and spread evenly throughout the solvent, forming a homogenous mixture called a solution. The solute particles become surrounded by solvent molecules, breaking their intermolecular forces and allowing them to mix at the molecular level.
What happens to molecules when they are 2 times molecular?
they dice apart
What happens to two liquids that are opposite in polarity?
Two liquids that are opposite in polarity are immiscible, meaning they do not mix together and instead form distinct layers. This is due to the difference in their electrostatic interactions and the inability to form stable molecular interactions.
When a substance is raised to its melting teperature what happens to the atom or molecules?
The inter-molecular bonds between the atoms/molecules are broken, releasing the atoms/molecules from a ridged structure to a freely moving mass.
What happens to molecules as energy is added and the temperature increases?
As energy is added and temperature increases, molecules gain kinetic energy and move more rapidly. This increase in movement can lead to stronger molecular interactions, changes in molecular configuration, and ultimately a change in the state of matter (e.g., from solid to liquid or gas).
What happens to the molecules when you boil water do they boils off or stay behind?
Whe you boil water, molecules of water "escape" into the atmosphere. The molecular structure of water is unaffected by boiling.
What happens in the process of diffusion?
During diffusion molecules move from a region of higher concentration to one of lower concentration by random molecular motion.
What happens if you reverse DC polarity of a lamp?
nothing
What happens to flammability as molecular size increases?
As molecular size increases, flammability tends to decrease. This is because larger molecules have a lower surface area-to-volume ratio, which makes it harder for oxygen to reach the interior of the molecule, inhibiting combustion. Additionally, larger molecules often contain more non-flammable components than smaller molecules.
What happens to all oxygen molecules that originated from carbon dioxide in the van niel experiment?
In the van Niel experiment, the oxygen molecules that originated from carbon dioxide are released as byproducts during the process of photosynthesis. These oxygen molecules are a result of splitting water molecules to produce molecular oxygen (O2) while converting carbon dioxide into carbohydrates.
When a solid dissolves in a liquid it seems to disappear into it. how is it possible?
The solid separates down to the molecular level - and they mix with the water molecules. We cannot see molecules with the naked eye !
What happens to the size of puddles when evaporation happens?
When evaporation occurs, the water molecules in the puddle transform into water vapor and rise into the air, causing the puddle to gradually decrease in size until it eventually dries up completely.
What happens to the particles of a ionic solid and a molecular solid when each mixes with water?
When an ionic solid mixes with water, the particles of the solid dissociate into separate ions, which then become solvated by the water molecules. In contrast, when a molecular solid mixes with water, the solid molecules remain intact and may dissolve or form a solution depending on the intermolecular forces between the molecules and water.
