Answer:
metal to non metal ratio is 97/21 = 4.62 or
82.2% metals, 17.8% non metals
Explanation:
How do the numbers of metal and non-metal elements compare? Estimate an approximate percentage difference. (learning about the periodic table if...
of 118 elements in the periodic table , 21 are non metals (even H has metallic properties when approching 0 degrees K)
this means there ar 21 nonmetals and 118-21=97 metals.

Answer:
Green food coloring diffusing through cookie dough.
Explanation:
Entropy is a physical quantity for an equilibrium thermodynamic system that measures the degree of organization of the system, or that is the ratio of an increase in internal energy to an increase in temperature of the system.
When the green dye diffuses through the cookie dough there is an increase in entropy, that is, there is an increase in system disorder at the molecular level, where a change in cookie dough occurs.
