How to calculate enthalpy change Why are decomposition reactions endothermic? How is an exothermic reaction identified? What conditions must be met by a thermochemical equation so that its standard enthalpy change can be given the symbol DeltaH_f^o (standard enthalpy of formation)?
How do you calculate dosing interval based on half-life? The half-life of a first-order reaction is 1.5 hours. How much time is needed for 94% of the reactant to change to product? Consider the following reaction: A B. The reaction is first order for A. If the rate constant for th...
enthalpies of the individual bonds, you can use the following relationship to calculate the total enthalpy change for the reaction. If it is negative, heat is released, and the reaction is exothermic; if positive, the reaction is endothermic (and will not proceed without the addition of energy...

To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is calculated, the mass can be found on a scale and the calculation of density can be complete...
Topic: How to calculate heat of solution and enthalpy of solution (Read 6252 times) Hi, my question is in the link below: https://www.dropbox.com/s/vr99iv1u9k56q3p/dd.png?dl=0 My attempted answer is below: I'm struggling to find the mass. Is the mass 50.0mL + 25.0mL = ...
Calculation of Theoretical Yield In chemistry terms we refer to yield as the quantity of product that can be produced from a reaction. Theoretical yield is the maximum amount of product that could be formed if conditions were perfect. Theoretical yield is based on the stoichiometry of the ...
How do you calculate Gibbs free energy? All you need to know is three out of four variables: change in enthalpy (ΔH), entropy (ΔS), temperature (T), or Gibbs free energy (ΔS)...Gibbs free energy calculator ΔG = ΔH − T * ΔS ; ΔH = ΔG + T * ΔS ; and. Δ...
