A wind-age tray is usually a stamped piece of sheet metal that is mounted between the crank shaft and the oil pan. On slow revving i.e. stock applications there benefit is slight.However race and high RPM applications claim that they actually free up more horsepower. wind-age tray acts like a scraper and removes the oil from the vortex letting it drain back to the oil pan. It does not actually touch the crank shaft but it is close enough to it to skim off the oil and let it drain.
To determine which reactant is the limiting reactant, first determine how much product would be formed by each reactant if all the reactant was consumed. The reactant that forms the least amount of product will be the limiting reactant. Calculate the yield of each reactant.
1 In a chemical reaction, the atoms and molecules produced by the reaction are called products. 2  In a chemical reaction, only the atoms present in the reactants can end up in the products. 3  No new atoms are created, and no atoms are destroyed.
