Two metal blocks that have slightly different temperatures are placed next to one another. After five minutes, they both have lower but equal temperatures. According to the law of conservation of energy, what most likely happened?
Ammonia, NH sub 3 , ΔH_f=−46.2kJ reacts with oxygen to produce water ΔH_f=−241.8kJ and nitric oxide, NO , ΔH_f=91.3kJ , in the reaction: 4 NH sub 3 g plus 5 cap o sub 2 g rightarrow 6 cap h sub 2 cap o g plus 4 NO g What is the enthalpy change for this reaction? Use ΔH_rxn=∑(ΔH_f_1products)−∑(ΔH_f_1reactants)
Complete combustion of a 0 point 3 5 0 g sample of a compound in a bomb calorimeter releases 14 point 0 kJ of heat. The bomb calorimeter has a mass of 1 point 2 0 kilograms and a specific heat of 3 point 5 5 the fraction with numerator cap j and denominator open paren g times degree cap c close paren If the initial temperature of the calorimeter is 22 point 5 times degree C , what is its final temperature? Use q is equal to m cap c sub p triangle cap t
