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) ...
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...
Both of these modern concepts are needed to really get to the more modern Delta G = - RTlnKeq in a satisfying way.The term ΣμidNi is a term added to the equation to account for the changes in material equilibrium. When a chemical reaction occurs the material composition of a system ...
How to calculate lattice enthalpy Calculate the standard enthalpy change of formation \Delta_f H^e, of hydrogen sulfide using the enthalpy change for __Reaction 1__ , and the standard enthalpy changes of combustion below. __Reaction 1:__2H_2S(g)+3O_2(g) \to 2SO_2(g)+2H_2 O(l)...
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, ...
However, the terrain below the basalt delta is all made of tough blocks like basalt and blackstone. So, it’s far harder to mine through them than netherrack. However, one more thing to keep in mind is the mobs that spawn in each biome. If you create a large enough area below, the ...
Consider the reaction: N_2(g) + 3H_2(g) rightarrow 2NH3(g) If the rate of the loss of hydrogen gas is 0.03 mol/L-s, what is the rate of production of ammonia? How does pressure affect equilibrium constant? The reaction 2NO(g) + Cl2(g) to 2NOCl(g) is carried ...
Explain how a chemical reaction can either release energy or store energy. What are some tips on how to do stoichiometry? What is the 1st law of thermodynamics? What is the difference between Gibbs free energy \Delta G and standard state free energy \Delta(G)^0?
