13.) The 2 factors that determine whether a reactino is spontaneous of nonspontaneous are
a.) entropy and disorder b.) entropy and energy c.) electronegativity and ionic charge d.) energy and heat of reaction

14.) in which of these systems is the entropy decreasing ?
a.) air escaping from a tire b.) snow melting c.) salt dissolving in water d.) a liquid cooling

15.) in thermo chemical equations, coefficients represent moles only. T or F ?

dS & dH
b.) entropy and energy



14.) in which of these systems is the entropy decreasing ?
d.) a liquid cooling


15.) in thermo chemical equations, coefficients represent moles only.
I can only think of examples where it is true


16.) the SI unit for heat is calories. T or F
False
"SI unit of energy, the joule"
