Iron can be extracted from its ores by heating it with carbon. Some students found that 6.4g of Fe2O3 reacted with 0.72g of C to produce 4.48g of Fe and 2.64g of CO2. Use the molar masses to deduce the balanced equation.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
