ASCO
AS = AHIT
AS > 0

< 0

Explanation:

Entropy is the measure of randomness or disorder of a system. If a system moves from  an ordered arrangement to a disordered arrangement, the entropy is said to decrease and vice versa.

For the reaction

In this reaction gaseous reactants are converting to solid products. The randomness will decrease and hence entropy will also decrease. Thus is negative or less than zero.

i believe the answer is a.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
