Water and its Characteristics
~ Cohesion: attraction of water molecules to each other
~ Polarity: when the centroid of the positive charge is different from the centroid of the negative charge.
~ Heat Storage: water can hold a lot of energy in it. it takes a long time to warm up and cool down.
~ pH: on the pH scale water is 0 so it is neither acidic or basic.
The water molecules are being attracted to the spider web.
The water molecules are being cohesive so the water bug cant break through it and is able to glide or walk on the water.
~ Monomer: a molecule of low molecular weight capable of reacting with identical or different molecules of low molecular weight to form a polymer.
~ Polymer: a large molecule composed of many subunits.
~ Hydrolysis: the breakdown of a compound when it reacts with water.
~ Condensation polymerization: the opposite of hydrolysis because it release water molecules instead of using them.
~ Carbohydrates: any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose
