Lewis structure of water The Lewis structures, also called Lewis-dot diagrams or electron dot diagrams are pictures that show the bonding between a pair of electrons and the atoms of a molecule. Each dot represents one electron. Two dots side by side represent a lone pair of electrons. To show a bond between atoms, a line representing a pair of shared electrons is placed between the two atoms.
Or, maybe you're wondering just how old the tires are on the motorcycle you just bought. Here's how to tell: Look on the sidewall of the tire for the DOT symbol. Follow the line of text and numbers after the DOT symbol until you reach the end. If the tire was manufactured in the year 2000 or later, the last 4 digits give the age. The last 2 digits give the year and the preceding 2 digits give the week of manufacture.
When you slide your hand across the tire, you get the impression of the tread feeling like the teeth on a saw. This type of wear is more pronounced on some tires than others and is caused by the fact that in a motorcycle tire, the tread is rounded instead of flat like a car tire.t sounds to me that the tire is under-inflated which causes more wear on the outsides of the tread, than on the center. Over inflating causes the opposite and wears more on the center of the tread. I hope that ois what you were asking about, and with Motorcycle tires, when in doubt through it out!!!
