1. INTRODUCTION All internal combustion engines generate power by creating explosions using fuel and air. These explosions occur inside the engine’s cylinders and push the pistons down‚ which turns the crankshaft. Some of the power thus produced is used to prepare the cylinders for the next explosion by forcing the exhaust gases out of the cylinder‚ drawing in air (or fuel-air mixture in non-diesel engines)‚ and compressing the air or fuel-air mixture before the fuel is ignited.

Stoichiometry February 28th‚ 2013 Abstract: The reactions of the Sodium Hydroxide and two acids‚ Hydrochloric Acid and Sulfuric Acid were performed. The heat given off by these two reactions was used to determine the stoichiometric ratio and the limiting reactants in each experiment. Introduction: Coefficients in a balanced equations show how many moles of each reactant is needed to react with each other and how many moles of each product that will be formed. Stoichiometry allows us to

intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass and volume. For volume of each liquid‚ the instruments used were a 50ml burette‚ a 50ml graduated cylinder and a 10ml gravity pipette. For each instrument above‚ the measurements were repeated 3 times. The mass of each sample was recorded by an electronic balance with the smallest gradation of 0.01g. The information collected then was used to determine
