Bond Energy and Enthalpy – Introductory Chemistry

WebEvaporation of sweat, which is 90 percent water, allows for cooling of an organism, because breaking hydrogen bonds requires an input of energy and takes heat away from the body. Conversely, as molecular motion decreases and temperatures drop, less energy is present to break the hydrogen bonds between water molecules. WebNotice that H—F also requires the largest input of energy to break the bond and therefore has the strongest bond. Electronegativity and Bond Types You have learned that when sodium and chlorine react, an electron is removed from Na and transferred to Cl to form Na + and Cl − ions. These ions form an ionic bond.
