Why do nutrition facts label differ for canned Garbanzo Beans (Chickpeas)? [closed]
Looking at canned Chickpeas Garbanzo Beans from several vendors, it seems some vendors use "prepared Garbanzo Beans" while others just used "Garbanzo Beans". Some also have ...

Isothermal Titration Calorimetry (ITC) to Determine the Critical Micelle Concentration (CMC) of Surfactans
Lately I found a paper from Smith et al. (2022), where isothermal titration calorimetry (ITC) was used to determine the critical micelle concentration (CMC) of different surfactants. However, as I am ...

Heat capacity of calorimeter
The problem is:
$\pu{30 mL}$ of water at $\pu{24.00 °C}$ were stored in a calorimeter in a laboratory experiment. Then, $\pu{40 mL}$ of water at $\pu{55.00 °C}$ were added to the calorimeter ...

What are the key differences between combustion of starch and sugar
I performed an energy content experiment the other day using a rudimentary bomb calorimeter. The experiment was comparing for the energy release of a sugary food (Arnott's Tiny Teddies) to the energy ...

How does one obtain K and stoichiometry from the Isothermal Calorimetry binding curve?
In Isothermal Calorimetry, I can appreciate that data is fitted to equations to obtain $K, \Delta H, \Delta G, \Delta S$ and stoichiometry, $n$.
However, I have seen from multiple sources that $K$ and ...

How is temperature inside a bomb calorimeter constant?
I've looked around and have been unable to find an answer.
When determining molar reaction enthalpy, you first perform the reaction in the steel bomb then measure the temperature change of the water ...

Why is there internal energy change in a bomb calorimeter?
In a bomb calorimeter, the reaction occurs at a constant volume, hence we say that the heat absorbed by the water in the surroundings is equal to the change in internal energy for the reaction. But, ...
