How much heat is produced by the complete reaction of 5.29 kg of nitromethane?

Complete reaction of nitromethane with what?

To determine the amount of heat produced by the complete reaction of nitromethane, we need to know the enthalpy change per mole of the compound. The enthalpy change (ΔH) can be found in a reference source, such as a chemistry textbook or an online database.

Once you have the enthalpy change per mole of nitromethane, you can use it to calculate the heat produced. Let's assume the enthalpy change (ΔH) for the reaction of nitromethane is ΔH = -500 kJ/mol.

Step 1: Convert the mass of nitromethane to moles.
Since the molar mass of nitromethane (CH3NO2) is 61.04 g/mol, we can calculate the number of moles by dividing the mass (in kilograms) by the molar mass:
Number of moles = mass (in kg) / molar mass (in kg/mol)

Number of moles = 5.29 kg / (61.04 g/mol * 1000 g/kg)
Number of moles = 0.0867 mol

Step 2: Calculate the heat produced.
The heat produced can be calculated using the equation:
Heat (q) = Number of moles * ΔH

Heat (q) = 0.0867 mol * -500 kJ/mol
Heat (q) = -43.35 kJ

Therefore, the complete reaction of 5.29 kg of nitromethane would produce approximately -43.35 kilojoules (kJ) of heat. The negative sign indicates that the reaction is exothermic, meaning it releases heat.
