Is, anyone out there realizing the benefits (or lack of) carbon handlebars? And, are you using the standard shaped racing bars or the wing or ram style bars?They seem to be about the same weight as aluminium barsAlso, does anyone know the standard mm drop? 42, 44, etc.Thanks in advance.
Carbon unlike aluminum will dampen road vibrationThey are more expensive and it you are racing or prone to put your bike down, aluminum may very well be the best choiceI use a carbon bar from performance bike that has worked very well and is only 190 gramsFind something that you like and ride with itThere are hundreds of different options that no one is the absolute best for everybody.
First question: The element with 8 electrons in its outer shell is always located at the end of each period, and it is called a noble gasThe noble gas belonging to the 2nd period is neon (Ne)Answer: The 2nd period element that has 8 electrons in its outer shell is neonSecond question: I am assuming that you want to calculate the amount of aluminum produced using 50grams of calciumFist, we need a balanced equation for the reaction: 3 Ca + 2 AlCl3 → 3 CaCl2 + 2 Al Next, we can use dimensional analysis and equation coefficients to convert 50grams of calcium to moles of calcium, to moles of aluminum, to mass of aluminumWe will need the following equalities to set up conversion factors: 1 mol Ca 40.08 g Ca 2 mol Al 3 mol Ca 1 mol Al 26.98 g Al [(50g Ca)/1][(1 mol Ca)/(40.08 g Ca)][(2 mol Al)/(3 mol Ca)][(26.98 g Al)/(1 mol Al)] 22.438455 g of Al or 22 g of Al rounded to two significant figures Answer: 22 grams of aluminum can be produced from 50grams of calcium.
