WebHydrogen bonding explains both the effectiveness of evaporative cooling (why sweating cools you off) and the low density of ice (why ice floats). Here, we’ll take a closer look at the role of hydrogen bonding in temperature changes, freezing, and vaporization of water. WebTwo molecules of water are held together by a hydrogen bond formed between the slight positive charge of the hydrogen and the slight negative charge of the oxygen. Water is a very versatile solvent, a quality traced to the polarity of the water molecule.

The most common … WebThe structure of an alcohol is composed of a hydroxyl group (Bonded oxygen and hydrogen) that is also bonded to a carbon atom. The carbon atom is then bonded to another carbon atom and/or hydrogen atom. In this case, the oxygen is bonded with the hydrogen, forming a hydroxyl group. The oxygen is then bonded to another carbon.
WebApr 10, 2024 · The procedure for determining ΔH vap goes like this: boil water in a kettle immediately record the (initial) mass of the just-boiled water + kettle right away, plug the kettle back in and start the timer the water should re-boil pretty much right away; record the time to boil off, say, 60 g of water record the (final) mass of the kettle + water
