Use Hess's Law to find the heat of reaction in the example below. N2O4 (g) longrightarrow 2NO2 (g) Given that: N2O4 (g) longrightarrow N2 (g) + 2O2 (g) (Delta H = 9.7 kJ) 2NO2 (g) longrightarrow 2O2 (g) + N2 (g) (Delta H = -67.7 kJ) Use He...
In order to calculate this experimentally you have to monitor either the concentration of the reactant or product as a function of time. Once you have measurements at different times you can then plot these values and find the instantaneous rate of the reaction or the slope of the line. Pret...
S(s) + O_2(g) \to SO2 (g) \ \ \ \Delta H_{rxn} = -296.8 kJ 2SO_2 (g) + O_2 (g) \to 2SO_3 (g) \ \ \ \Delta H_{rxn} = Using the following information and Hess's Law, calculate the change in enthalpy for the reaction CH_4(g) ...
A rocket engine is generally throwing mass in the form of a high-pressure gas. The engine throws the mass of gas out in one direction in order to get a reaction in the opposite direction. The mass comes from the weight of the fuel that the rocket engine burns. The burning process accel...
Back in the 1990s, Philip Strong was able not only to describe the psychological impact of epidemics on social order but also to model it. He observed that the early reaction to major fatal epidemics is a distinctive psycho-social form and can be modeled along three main dimensions: fear, ...

Calculate the standard enthalpy change for the reaction: 2C_8H_{18}(l) + 17O_2(g) to 16CO(g) + 18H_2O(l). Given: 2C_8H_{18}(l) + 25O_2(g) to 16CO_2(g) + 18H_2O(l), Delta H = -11020 kJ/mol 2CO(g)+ O_2( ...
Is the molar enthalpy of formation a type of enthalpy change? Or, is it just how much energy is absorbed as heat when one mole of a compound is formed? delta H is +269.0 kJ for the reaction 2Ba(s) + O2(g) = 2BaO(s) deltaH = -1107.0 kJ Ba(s) + CO2(g) + O2(g) = BaC...
The orbiter consists of the following parts: crew compartment - where you will live and work forward fuselage (upper, lower parts) - contains support equipment (fuel cells, gas tanks) for crew compartment forward reaction control system (RCS) module - contains forward rocket jets for turning the...
