STOICHIOMETRY OF GASOLINE. AN INTRODUCTION The internal combustion engines burn fuel to create kinetic energy. The burning of fuel is basically the reaction of fuel with oxygen in the air to form water and Carbon dioxide as the major end product . The amount of oxygen present in the cylinder is the limiting factor for the amount of fuel that can be burnt that is to say it determines the level of burning in our combustion engine. If there’s too much fuel present‚ not all fuel will be burnt and un-burnt

Chemistry Lab Report Stoichiometry Design Experiment Percentage Yield of Calcium Carbonate and HCl I. Background Information When marble chips and hydrochloric acid are added together‚ they form sodium chloride‚ water‚ and carbon dioxide. This reaction can be displayed by the balanced equation below; CaCO3 (s) + HCl (l) NaCl(s) + H2O(l) + CO2 (g) As the carbon dioxide is formed‚ it will leave the open beaker as a gas. This will result in a loss of mass. The mass change can then be

LAB 7: SECURITY BASIC Task 1: Hardware firewalls are integrated into the router that sits between a computer and the Internet. They typically use packet filtering‚ which means they scan packet headers to determine their source‚ origin‚ destination addresses and check with the existing user defined rules to make an allow/deny decision. . Speed: Hardware firewalls are tailored for faster response times‚ so it can handle more traffic loads. Security: A firewall with its own operating system is

Stoichiometry of a Precipitation Reaction Purpose: The purpose of this lab is to calculate the theoretical‚ actual‚ and percent yield of the product from a precipitation reaction. Also‚ to learn concepts of solubility and the formation of a precipitate. Procedure: Weigh out your 1.0g of CaCl2-2H20 and put it into the 100mL beaker‚ Add your 25mL of distilled water and stir to form the calcium chloride solution. Next‚ use stoichiometry to determine how much Na2CO3 and put it into a small

Abstract: The main objective of this Lab‚ is to experiment with stoichiometric measurements‚ since it is one of the most important subjects in chemistry. In addition‚ stoichiometric measurement is widely used in chemistry‚ because it indicates the proportion of mass in which various substances react. By examining one specific example of stoichiometric determination‚ which is: “Stoichiometry and limiting reacting”‚ we found out the different mass proportions in which substance react. In this case
