An “instant cold pack” contains water and an inner pouch with 47.2 g of KNOZ. When the inner pouch is
broken and all of the KNO, is completely dissolved in water, the dissolving process absorbs 16.3 kJ of energy
(which "feels cold”). Calculate molar heat of solution (AHº) for this process in kJ/mol of KNO,.
" include correct sig figs, units, AND correct + or - sign "

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance
