The redox balance of alcoholic fermentation is achieved by the regeneration of NAD + during the reduction of acetaldehyde to ethanol which is catalyzed by alcohol deydrogenase The ATP yield of alcoholic fermentation is 1 or 2 mol of ATP per mole of glucose oxidized via ### Based on Bohr's theory which of the following transitions

The energy is high when the differences in energy levels are large Therefore the transition for the hydrogen atom that emits the most energy is from n = 6 to the n = 2 level Hence the correct option for the transition for the hydrogen atom that emits the most energy is ### Energy in a Ton of Coal

Ever wondered how much energy you could get out of a ton of coal but never had the time to research it? Well if you ever did here's the answer to your pondering On average a ton of coal produces 21 to 22 gigajoules of energy The amount of energy produced by a ton of coal is largely dependent upon the type of coal being burned ### How to Calculate the Amount of Heat Released

TL DR (Too Long Didn't Read) To calculate the amount of heat released in a chemical reaction use the equation Q = mc ΔT where Q is the heat energy transferred (in joules) m is the mass of the liquid being heated (in kilograms) c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius) and ΔT is the change in temperature of the liquid (degrees Celsius) ### Calculation of Ethanol Production from Fermentation

Calculation of Ethanol Production from Fermentation This is an explanation of how students can calculate the amount of ethanol produced from their fermentations The two things that must be measured are 1) the volume of the starting culture and 2) the volume of the gas produced during fermentation To obtain the ### 5 3 Enthalpy – Chemistry

Starting with a known amount (1 00 L of isooctane) we can perform conversions between units until we arrive at the desired amount of heat or energy The enthalpy of combustion of isooctane provides one of the necessary conversions Table 2 gives this value as −5460 kJ per 1 mole of isooctane (C 8 H 18) Using these data ### Biofuels

Propanol is the forgotten alcohol fuel but for good reason Propanol is the most difficult and expensive alcohol to produce Because its energy gains over ethanol are minimal the large scale production and use of this fuel is hard to justify Propanol is not without its uses however The gram-formula mass of is 474 grams per mole Base your answer to the following question on Draw a correct Lewis electron-dot structure for each of the following a An atom of hydrogen Base your answer to the following question on the information below and on your knowledge of chemistry ### The complete combustion of acetylene C 2 H 2 ( g

FUELS AND COMBUSTION 3 1 Introduction to Combustion Fuels are evaluated in part based on the amount of energy or heat that they release per unit mass or per mole during combustion of the fuel Such a quantity is The mole fraction of water vapor in the mixture of Example 3 1 is 0 55 ### Combustion Reaction: Examples And Definition

Hydrogen combustion reactions are very energetic and have a high mass-to-energy ration so it requires less amount of fuel per unit of energy output than traditional methods of rocket propellant In Cars Most modern cars operate on some kind of internal combustion engine which works by combusting gasoline in the presence of oxygen ### Calculate Empirical and Molecular Formulas

The empirical formula tells us the ratio between atoms of the elements which can indicate the type of molecule (a carbohydrate in the example) The molecular formula lists the numbers of each type of element and can be used in writing and balancing chemical equations However neither formula indicates the arrangement of atoms in a molecule ### Molar Heat of Combustion of Fuels Chemistry Tutorial

From the table we see that 1 mole of methane gas CH 4(g) undergoes complete combustion in excess oxygen gas releasing 890 kJ of heat The molar heat of combustion of methane gas is given in the table as a positive value 890 kJ mol-1 The enthalpy change for the combustion of methane gas is given in the table as a negative value ΔH = -890 kJ mol-1 because the reaction produces energy (it ### Molar Heat of Combustion of Fuels Chemistry Tutorial
