... Za) (Equation 7) Same is true for component c, L₀V₂ = (Zc - Yc₂) (Xc₀ -Zc) (Equation 8) Figure 2. A diagram showing the graphical addition rule. These two equations relate the composition of the resultant mixture to the compositions and masses of the original two mixtures. By equating Equations 7 and 8 and then manipulating the equation, the equation {(Xc₀ - Zc)/(Xa₀ - Za)} = {(Zc - Yc₂)/(Za - Ya₂)} which proved that α = β The ... (hΣ - hΣ₁). The inverse lever arm rule that can be applied will be the ratio of V₂/Σ = (h₀ - hΣ₁)/(h₀ - H₂). Solvent-free ba...

... In these cases it is often possible to determine the enthalpy of reaction by direct measurements on more accessible related systems and then applying Hess' Law. Aim: to determine the change in enthalpy for the hydration of magnesium sulfate using Hess' Law. Hypothesis: It looks like ... there are being more bonds formed than broken in this reaction, therefore, I think the change in enthalpy will be exothermic. Variables: - Temperature of ... directly, we will use the following two equations to calculate the enthalpy change for the equation above. MgSO4 + H2O =  Mg2+ + SO42- + H2O MgSO4...
