a) The thermochemical equation for the combustion reaction is:
2Ca(s) + O2(g) -> 2CaO(s) + 1200 kJ
b) The above reaction is exothermic. This is because heat is released in the reaction, as indicated by the 1200 kJ of heat being released. In an exothermic reaction, the products have a lower energy than the reactants, and the excess energy is released in the form of heat.
When 2 moles of solid calcium, Ca, combines with 1 mole of oxygen gas, O2, 2 moles of solid calcium oxide, CaO, is formed and 1200 kJ of heat is released. Inh nhan
a) Write the thermochemical equation for the above combustion reaction.?
b) Is the above reaction exothermic or endothermic?
