A negative enthalpy change (ΔH) for a molecule indicates that the reaction or process is exothermic, meaning it releases heat to the surroundings. This typically signifies that the products of the reaction are more stable than the reactants, resulting in a release of energy when the reaction occurs. In thermodynamic terms, a negative ΔH suggests that the reaction is favorable and can occur spontaneously under certain conditions.
A negative standard enthalpy of formation (ΔH_f) for a molecule indicates that the formation of that molecule from its constituent elements releases energy, signifying that the process is exothermic. This typically suggests that the molecule is stable and favored under standard conditions. In practical terms, it implies that the products of the reaction are lower in energy compared to the reactants, contributing to the overall stability of the compound formed.
It is because it has positive charges (from 2 H) and negative charges (from O), that the charges balance out (negative + positive = neutral) (2H+) + (O2-) -----> H2O
When a molecule becomes more negative, it means that it has gained additional electrons, resulting in an increase in its overall negative charge. This can occur through processes such as electron transfer or the formation of chemical bonds with more electronegative atoms, causing the molecule to exhibit a greater overall negative charge distribution.
In the molecule H₂S (hydrogen sulfide), sulfur (S) will have a partial negative charge. This is due to its higher electronegativity compared to hydrogen (H), causing the electron cloud to be drawn closer to sulfur. As a result, sulfur acquires a partial negative charge, while the hydrogen atoms carry a partial positive charge.
In a water molecule (H₂O), there are two regions of negative charge, primarily associated with the oxygen atom. Oxygen is more electronegative than hydrogen, leading to a partial negative charge on the oxygen and a partial positive charge on the hydrogen atoms. This creates a polar molecule with a dipole moment, where the negative charge is concentrated near the oxygen atom.
From H and O, oxygen is the most electronegative, so that the negative side of the H-O-H 'triangle' with O in top.
A zwitterion, if you mean formal charges. If you just mean relatively positive and negative, then a polar molecule.
Do you mean hydrogen bond? This is an electrostatic (mainly) attraction, for example, between the H (slightly positively charged) on one water molecule with the O (slightly negative) on another.
If you mean "Why is a molecule polarized" it would be because there is a more negative charge to one end of the molecule than the other.

Negative oxidation typically refers to reduction, which is the gain of electrons or a decrease in oxidation state of a molecule. In this process, a molecule or atom undergoes a reduction reaction by accepting electrons.
When a molecule becomes more negative, it means that it has gained additional electrons, resulting in an increase in its overall negative charge. This can occur through processes such as electron transfer or the formation of chemical bonds with more electronegative atoms, causing the molecule to exhibit a greater overall negative charge distribution.
A water molecule is polar because it has a slight negative charge near the oxygen atom and slight positive charges near the hydrogen atoms. This polarity allows water molecules to form hydrogen bonds with each other, resulting in properties like high surface tension and the ability to dissolve many substances.
there is no negative pole in h2o molecule
Energy was released when the molecule was formed from its elements
