How many kilojoules of heat are produced when 34.0 g of Fe2O3 reacts with an excess of CO according to the following reaction? Fe2O3 + 3 CO 2 Fe + 3 CO2 ΔH = -26.3 kJ
Answers
The heat produced when iron oxide reacts with carbon monoxide is -23.47 kJ/mol.
What is the enthalpy of reaction?
The standard enthalpy of the reaction is given by the enthalpy of formation of the products and the reactants. The reactants and the products of the reaction are:
Fe₂O₃ (s) + 3CO (g) → 2Fe(s) + 3CO₂ (g)
We know,
The standard enthalpy of formation of iron oxide = −825.50 kJ/mol
The standard enthalpy of formation of carbon monoxide = −110.53 kJ/mol
The standard enthalpy of formation of carbon dioxide = −393.52 kJ/mol
The standard enthalpy of reaction is calculated as:
[tex]\rm \Delta H_{rxn}[/tex] = [2(0) + 3(−393.52)] - [1(-825.50) + 3(-110.53)]
= (0−1180.56+825.50+331.59)
= −23.47 kJ/mol
Therefore, −23.47 kJ/mol is produced.

The densities of copper, silver, iron, and magnesium are in that order. You are given grams of each metal. Which one has the largest volume
Answers
Density is the ratio of mass to volume. The substance with the lowest density has the largest volume. The volume of magnesium will be the largest.
What is density?Density is the mass per volume of the substance. It is denoted by the Latin letter rho (ρ) or D. It is the division of the mass in kilograms to the volume in cubic meters.
The relation of the density is inversely proportional to the volume and when the order is given in increasing order of density then magnesium will have the largest volume as it has the least density.
Therefore, magnesium has the largest volume.

The enthalpy change of the given reaction is negative, so the reaction is an exothermic reaction.
What is enthalpy change of a reaction?Enthalpy change of a reaction is the energy changes that occur when reactant molecules form products.
Enthalpy is the heat content of a substance.
When enthalpy change is positive, the heat content of the product is greater than that of the reactant and the reaction is an endothermic reaction.
Whereas, when enthalpy change is negative, the heat content of the reactant is greater than that of the product and the reaction is an exothermic reaction.
Therefore, since the enthalpy change of the given reaction is negative, the reaction is an exothermic reaction.
