1. If an iron ring with a mass of 0.0055 kg changes temperature from 25.0°C to 28.0ºC, what is the change in energy? Is this process endothermic or exothermic? The specific heat capacity of iron is 0.444 J/g °C. [3 Marks] 2. Calculate the amount of heat (in kJ) required to decompose 188 g of NaHCO3(s). [3 Marks] 2 NaHCO3(s) + 85 kJ → Na2CO3(s) + H₂O(l) + CO2(g)
