Specific Heat Lab Report “Here are the facts we confront; No one is against conservation. No one is against alternative fuel sources.” – J. D. Hayworth Research Question: Does the number of hydrocarbons that a fuel is composed of affect how much it will ignite? If so‚ consider the following: What is the quantity and concentration of the combustion that is released and how can that be measured in other (more coherent) means? These are the fuels that were seasoned throughout the

Heat engine lab Intro: when an engine runs‚ it pumps pistons that move up and down and provide energy to the engine to it to go. These pistons move because of pressure and heat. This work done on the system is not only mechanical but its also thermodynamic. When a piston undergoes one full cycle its displacement is zero because it comes back to its resting place. This means that its net thermodynamic work to be done should also be zero‚ as well as its total internal energy. In order to test this

Proportions. In our final lab‚ we took a sample of potassium chlorate and heated it in a crucible to drive off the oxygen. We did this to measure and find the amount of oxygen that was in it. This was to verify the Law of Definite Composition. Aspect 2: In our investigation of the Atomic laws we had some major results in all 3 experiments. In the Conservation of Mass Lab‚ we found that the total combined mass was equal to the original individual masses of the substances. In the Oreo Lab‚ our ratio result

product which is Magnesium Metal. Another objective was determining the formula of the compound that results when Magnesium and Oxygen react. Theory: The purpose of this lab was to confirm the chemical formula of magnesium oxide by comparing the masses of pure magnesium solid prior to any reaction and magnesium oxide solid after a reaction between all of the magnesium and oxygen from the air when heated from a Bunsen burner in a crucible. Using molar masses of both magnesium and oxygen‚ an expected

Lab 19A Answers: 1) If we increase the molarity of NaOH from 0.1M to 0.2M‚ it will actually take less number of drops in order to change the color of the solution. This is because the more concentrated a substance is‚ less of the substance is needed to cause an equilibrium shift. 2) When you add 6.0M NaOH into the iron (III) thiocyanate ion equilibrium system‚ the concentration of Fe3+ ion decreases. This causes the equilibrium system to shift to the left (reactant) side. This is why the solution

BALANCE LAB Introduction The purpose of this lab is to become familiar with how to use the ChemLab program for determining mass using both the centigram balance and the electronic balance. Using the centigram balance‚ the mass‚ in grams‚ of a copper slug will be determined by both direct weighing and weighing by difference techniques. Using an electronic balance‚ the wight of a copper slug will be determined by also utilizing direct weighing and weighing by difference. Average mass of a

Pre-Lab Discussion An empirical formula is a formula for a chemical compound found by direct laboratory examination. Laboratory procedures allow the chemist to find the simplest whole number ratio of elements within the compound. In order to find the true molecular formula‚ the chemist also needs to know the compound’s molecular mass. The general procedure is to use laboratory techniques to determine the mass of each element in the compound. In this lab‚ we will react a known quantity of magnesium
