What is the chemical equation for the combustion of liquid acetone?
Problem: Complete combustion of 1 mol of acetone (C 3H6O) liberates 1790 kJ:C3H6O (l) + 4 O 2 (g) → 3 CO2 (g) + 3 H2O (l) ΔH° = -1790 kJUsing this information together with data from Appendix C, calculate the enthalpy of formation of acetone.
What is the equation for methane and complete combustion?
The combustion of methane is represented by the equation: CH4 + 2O2 → CO2 + 2H2O. The combustion of methane gas heats a pot on a stove.
What is produced when acetone is burned?
Acetone is produced and disposed of in the human body through normal metabolic processes. It is normally present in blood and urine. People with diabetic ketoacidosis produce it in larger amounts….Acetone.

What is the incomplete combustion of methane?
The incomplete combustion of methane can result in a slew of partially oxidized products, including CO, but also methanol, formic acid, formaldehyde, and higher hydrocarbons also.
Is acetone flammable or combustible?
Acetone, also known as propanone, is a clear, colorless liquid that is highly flammable. It is not necessarily a household word, but this will ring a bell: nail polish remover.
What functional group is acetone?
ketone
In chemistry, a ketone /ˈkiːtoʊn/ is a functional group with the structure R2C=O, where R can be a variety of carbon-containing substituents. Ketones contain a carbonyl group (a carbon-oxygen double bond). The simplest ketone is acetone (R = R’ = methyl), with the formula CH3C(O)CH3.
What is the chemical equation for methane burned with 25% excess air?
The chemical equation for methane burned with 25% excess air can be expressed as CH4 + 1.25 x 2 (O2 + 3.76 N2) -> CO2 + 2 H2O + 0.5 O2 + 9.4 N2 Excess Air and O 2 and CO 2 in Flue Gas Approximated values for CO 2 and O 2 in the flue gas as result of excess air are estimated in the table below:
Which is an example of stoichiometric combustion of methane?
Example – Stoichiometric Combustion of Methane – CH4. The most common oxidizer is air. The chemical equation for stoichiometric combustion of methane – CH4 – with air can be expressed as. CH4 + 2(O2 + 3.76 N2) -> CO2 + 2 H2O + 7.52 N2. If more air is supplied some of the air will not be involved in the reaction.
What is the chemical equation for the combustion of ethanol?
For ethanol, the constants a, b and c are 2, 6 and 1, respectively, and the chemical equation for the combustion of ethanol: The standard heat of formation of liquid ethanol, ΔH f°(C 2H 6O, l), is -277.6 kJ/mol.
How to calculate heat of combustion in chemistry?
For compounds containing carbon, hydrogen and oxygen (as many organic compounds do), a general combustion reaction equation will be: C a H b O c + (a + ¼b – ½c) O 2 → aCO 2 (g) + ½bH 2 O (l) + heat of combustion. and the heat of combustion can be calculated from the standard heat of formation of all compounds taking part in the reaction:
