Aim To investigate the effect of molar mass on the molar heat of combustion of adjacent members of a homologous alcohol series. Introduction Chemists refer to the energy stored in a substance as the heat content or enthalpy of the substance. The heat of reaction is determined by the difference in the enthalpy between the reactants and products. The molar heat of combustion of a substance is the quantity of heat liberated when one mole of that substance is burnt completely in air. In the case

Design Objective: Find the standard molar enthalpy of combustion for magnesium. Manipulated Variables- volume of HCl‚ length of magnesium strip‚ mass of magnesium oxide‚ Controlled Variable- type of calorimeter (Styrofoam cup) Responding Variable- change in temperature Procedure: 1. Cut out 3 pieces of magnesium strips each with lengths of maximum 5 centimeters. 2. Measure and record the lengths of the magnesium. 3. Scrub the magnesium strips with steel wool to clean out impurities

chemistry‚ an alcohol is an organic compound in which the hydroxyl functional group (-OH) is bound to a carbon atom. In particular‚ this carbon center should be saturated‚ having single bonds to three other atoms.[1] An important class of alcohols are the simple acyclic alcohols‚ the general formula for which is CnH2n+1OH. Of those‚ ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages‚ and in common speech the word alcohol refers specifically to ethanol. Other alcohols are usually

Measuring the enthalpy change of vaporisation of water You should attempt this part of the activity even if you have not seen the demonstration of the practical. 1. Calculate a value for ∆Hvap for water in KJ mol-1 using the data from the demonstration. Also‚ calculate ∆Hvap from the following data gathered by a student; 8100 J were needed to distil 2.95g of water. a) Explain why the boiling tube was surrounded with expanded polystyrene (or other similar insulation)‚ but the condenser was left

How much alcohol do teens use? Alcohol is the most frequently used drug by teenagers in the United States. About half of junior high and senior high school students drink alcohol on a monthly basis‚ and 14% of teens have been intoxicated at least once in the past year. Nearly 8% of teens who drink say they drink at least five or more alcoholic drinks in a row (binge drink). What are the dangerous effects of alcohol use in teens? Just a few of the many dangerous effects of alcohol use in teens

¬¬¬¬In this lab‚ we explored the theory of combustion and used it to create and biodiesel. Diesel is a common fuel used to power many large trucks and heavy equipment (such as tractors and backhoes). Diesel fuel is made from crude oil that was formed over millions of years by the decomposition of prehistoric plants and animals. Through the use of an oil well‚ crude oil is pumped out of the ground and transferred (often by large ocean tankers) to oil distillation units. Crude oil contains widely varying
