My attempted answer is below: I'm struggling to find the mass. Is the mass 50.0mL + 25.0mL = 75.0mL solution It says to assume 1mL solution = 1g solution Is this referring to the solution or just the water? If it is referring to the solution, would the mass be 75.0g? q(soln)=...
What is the difference between enthalpy change and enthalpy of reaction? Explain the method to find the enthalpy of the product and the reactant in a chemical reaction. Is the molar enthalpy of formation a type of enthalpy change? Or, is it just how much energy is absorbed as heat when ...
How to convert Celsius to Kelvin formula How to calculate enthalpy of vaporization? What is the unit of enthalpy? How many calories are in a kilocalorie? What amount of heat (in kJ) is required to convert 10.1 g of an unknown liquid (MM = 83.21 g/mol) at 19.2 deg C to a gas at ...
Reread the homework/quiz question and determine what information you can extract from the question. You will probably be given a reaction enthalpy, the calorimeter constant and the heat capacity of the mixture formed by the reaction in the calorimeter, together with the starting temperatures. Assume...
Moran et al, Fundamentals of Engineering Thermodynamics, presents a pressure-enthalpy diagram for CO2 that can be used to follow the isentropic line down to the 2 phase envelope. Is this the diagram you're referring to? It says R744 but that should be the same as CO2. I'm still unsure...
Here we uncover the physicochemical underpinnings of how evolutionarily conserved compositional biases influence the phase behaviour of PLCDs. We interpret our results in the context of the stickers-and-spacers model for the phase separation of associative polymers. We find that tyrosine is a stronger...

The calorimetric measurements of the heat of dissolution of anhydrous and hydrated compounds provide the enthalpy of formation to form elements. The enthalpies of hydration are obtained by measuring the difference in the enthalpy of the solution in HF acid at approximately 70°C, of a hydrated and...
9) that losses of conformational degrees of freedom in the protein upon binding the ligand is the dominant contributor to the entropic barrier in the binding of ligands by proteins. The more extensive the contacts between the ligand and the protein, the more negative the enthalpy of binding and...
Specific Heat Capacity (c here) of a substance is the heat required (q) to raise the temperature of 1 unit mass of that substance by 1 unit c=qmΔT Where ΔT is the change in temperature The more heat you require to change the temperature of one unit mass of a substance by one ...
