5. How might endothermic reactions be applied in our daily lives? Do not just give examples explain how this might be used. (think about what an
endothermic reaction does, then think about when that might be useful):

What is the molar mass of potassium nitrate, kno3

Which statement best describes the flow of energy in this scenario

The table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of tthe table compares the number of electrons in two unknown neutral atoms. comparison of electrons atom number of electrons a 9 d 11 use this information to determine the number of valence electrons in the atoms. which of the following correctly compares the stability of the two atoms? both are unreactive. both are highly reactive. a is unreactive and d is reactive. a is reactive and d is unreactive.
