A 0.500 g sample of TNT (C2H5N206) is burned in a bomb calorimeter containing 610 grams of water at an initial temperature of 20.0°C. After the reaction, the final temperature of the water is
22.7°C. The heat capacity of the calorimeter is 420 J/°C.
How much heat was produced in the combustion of TNT?
A. 3374kJ
B. 8.04kJ
C. 2.97kJ
D. 8025 kJ
E. 3.37kJ
Was the heat released or absorbed by the water and calorimeter?
A. Absorbed
B. Released

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

it is the most commonly accepted one

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
