La mayoría de las reacciones químicas cuando se les aumenta la temperatura

It is a mixture. simply put, a compound must be pure, that is, of only one chemical structure and composition. a mixture is made of different chemical substances (i.e. elements, molecules, compounds) that are not chemically bonded to each other, but instead physically grouped together, as in the case of gasoline (a homogeneous solution).

The breaking apart of glucose, which involves spontaneous reactions 

N= 3.2 moles, t = 50 + 273 = 323 k, p = 101.325 kpa, r = 8.314 l.kpa/k.mol pv = nrtv = nrt / p substituting.v = (3.2 mole)(8.314 l.kpa/k.mol )(323 k) / (101.325 kpa)hope this
