I’m assuming in this scenario that 2.5 mols of Fe2O3 is reacting with excess reactant. Based on the balanced equation, you can see that there’s a 1:2 ratio between Fe2O3 and Fe. This means that to find the mols of Fe formed, you need to multiply the mols of Fe2O3 by 2.
2.50mol Fe2O3 * 2mol Fe/1 mol of Fe2O3 = 5.00mols Fe.

Heat energy can be calculated by using the specific heat of a substance multiplying it to the mass of the sample and the change in temperature. It is expressed as:
<span>
Energy = mCΔT
</span><span>Energy = 132 (0.385) (45 - 32.2)
</span><span>Energy = 650.50 J</span>
Answer:
Heating water until it boils. The water particles would gain thermal energy from the heat source and there would be an increase in the kinetic energy between the water particles. During this stage, the temperature of the water particles remains the same as the thermal energy is used to break the strong bonds of attraction between the water particles so that they can be further apart and transition from the liquid state to the gas state.
