Because theyre polarized, two adjacent H₂O (water) molecules can form a linkage known as a hydrogen bond, where the (electropositive) hydrogen atom of one H₂O molecule is electrostatically attracted to the (electronegative) oxygen atom of an adjacent water molecule.

Consequently, molecules of water join together transiently in a hydrogen-bonded lattice. 4.4: Polar and Non-polar Covalent Bonds - Chemistry LibreTexts while in a covalent bond , atoms have the same electronegativity values al one another, that is why electrons ase shared between atoms . Therefore, the original substance is a compound, The chemical reaction with acid changed, showing that the sample was broken down by heating. Although the resulting molecule is neutral, at close distances the uneven charge distribution can be important. She is finding one equation to be very difficult to balance. Carbons ability to form bonds with four other atoms goes back to its number and configuration of electrons. ethylene's The heating changed some of the sample to gas, causing the mass to decrease without breaking down the sample.
