Equation for the combustion reaction of a candle?
The combustion reaction of a candle can be represented by the equation: C25H52 + 38O2 → 25CO2 + 26H2O. This equation shows the burning of the paraffin wax (C25H52) in the presence of oxygen (O2) to produce carbon dioxide (CO2) and water (H2O) as the main products of combustion.
Molar Enthalpy of Candle Wax C25H52?
The molar enthalpy of combustion for candle wax (C25H52) is approximately -9866 kJ/mol, meaning this much energy is released when one mole of candle wax is burned completely in oxygen.
What is the balanced chemical equation for a burned candle?
The balanced chemical equation for a burned candle is C25H52 (wax) + O2 (oxygen) -> CO2 (carbon dioxide) + H2O (water) + heat. This represents the combustion reaction that occurs when a candle burns, turning the wax and oxygen into carbon dioxide, water vapor, and releasing heat.
What is the balanced equation for the complete combustion of wax C25H52 in a stream of air?
Hint , in complete combustion all the carbon ends up as CO2 so 25 CO2 all the hydrogen ends up as water so 26H2O Work out the number of O2 molecules you need to balance the equation. C25H52 + 38O2 -> 25CO2 + 26H2O In reality it is difficult to ensure complete combustion- candles burn with a smokey flame indicating that carbon is not fully oxidised.
What is the difference between the heat of reaction and the heat of combustion?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction, while the heat of combustion specifically refers to the heat released during the combustion of a substance with oxygen.

What are the reactants of the incomplete combustion of wax?
It is happening in low O2 concentration. it wll form unburnt C atoms.
What is the experimental molar heat of combustion?
The experimental molar heat of combustion is the heat released by the total combustion of a substance, determined in a calorimeter.
What do you call the heat released when 1 mole of a substance undergoes complete combustion?
You think probable to molar heat, expressed in J/mol.

How do you calculate the heat of combustion for a given substance?
To calculate the heat of combustion for a substance, you can use the formula: Heat of combustion (mass of substance) x (heat capacity) x (change in temperature). This formula helps determine the amount of heat released when a substance undergoes complete combustion.
What are the products formed when a candle is burned write an appropriate reaction equation?
When a candle is burned, it undergoes combustion to produce carbon dioxide and water vapor. The balanced reaction equation for the combustion of a candle can be represented as: Candle wax (C25H52) + 38 O2 → 25 CO2 + 26 H2O
What energy produces fossil fuel?
Through combustion they produce heat.
Why charcoal have high value of heat combustion than petrol?
Petrol has a higher value of the heat of combustion.
