To find the enthalpy change (Hreaction) in J/mol, you divide the total energy used by the number of moles. Here, 24 J of energy is used for 3 moles of the compound. Therefore, Hreaction = 24 J / 3 moles = 8 J/mol.
-14 J/mol
To find the change in enthalpy (ΔH) for the reaction in J/mol, divide the total energy produced by the number of moles. For 6 moles producing 84 J, ΔH = 84 J / 6 moles = 14 J/mol. Thus, the change in enthalpy for the reaction is 14 J/mol.
To find the enthalpy change (( \Delta H )) per mole of the compound, divide the total energy produced by the number of moles. In this case, ( \Delta H = \frac{84 , \text{J}}{6 , \text{moles}} = 14 , \text{J/mol} ). Therefore, the ( \Delta H ) for the reaction is 14 J/mol.
Carbon dioxide is the limiting reagent.
The enthalpy change for the reaction would be -8 J/mol, as it is the energy change per mole of the compound reacted.
The heat of reaction per mole can be calculated by dividing the energy produced by the number of moles. In this case, 84 J of energy produced by 6 moles of the compound gives a heat of reaction of 14 J/mol.

12 J/3 moles = 4 J/mole. Thus, H of reaction in kJ/mole = 0.004 kJ/mole
84 J/6 moles = 14 J/mole = ∆H
The enthalpy change (ΔH) per mole can be found by dividing the energy produced by the moles of the compound. In this case, ΔH = 84 J / 6 mol = 14 J/mol. Therefore, the enthalpy change per mole of the compound is 14 J/mol.
To find the enthalpy change (( \Delta H )) per mole of the compound, divide the total energy produced by the number of moles. In this case, ( \Delta H = \frac{84 , \text{J}}{6 , \text{moles}} = 14 , \text{J/mol} ). Therefore, the ( \Delta H ) for the reaction is 14 J/mol.
Carbon dioxide is the limiting reagent.
This is the number before a chemical compound.
The compound 2NaCl + Br2 is not a specific compound itself. It represents a chemical reaction where two moles of sodium chloride (NaCl) react with one mole of bromine (Br2). The products of this reaction would be sodium bromide (NaBr) and possibly other byproducts depending on reaction conditions.
To convert from the mass of a compound in grams to the amount of that compound in moles, you need to divide the mass of the compound in grams by its molar mass (which is found on the periodic table). This will give you the number of moles of the compound. The formula to use is: moles = mass (g) / molar mass.
