A) A sample of solid copper is heated with an electrical coil.If 72.4 Joules of energy are added to a 11.4 gram sample and thefinal temperature is 38.3°C, what is the initial temperature of thecopper? Answer:_________________ °C.
B)When NO(g) reacts withH2(g) to formN2(g) andH2O(l) , 376 kJ ofenergy are evolved for each mole ofNO(g) that reacts.
Write a balanced thermochemical equation for the reaction with anenergy term in kJ as part of the equation. Note that the answer boxfor the energy term is case sensitive.
Use the SMALLEST INTEGER coefficients possible and put theenergy term (including the units) in an appropriate box. If a boxis not needed, leave it blank.
