If a reaction is performed in 525 g of an unknown heat capacity and the initial temperature of a reaction is 23.8°C and the final temperature of a reaction is 35.2°C,
what is heat capacity of the liquid (in units of J/g.°C) if 22.2 kJ of heat is released in
the chemical reaction?

Click the button that shows the correct relationship of the electron affinities of the elements sodium and phosphorus. sodium’s electron affinity value is more negative than the electron affinity value of phosphorus. phosphorus’ electron affinity value is more negative than the electron affinity value of sodium. this information cannot be determined using the periodic table. answer is b on e2020.
