The question is above, please give me an example of how/where an isomer is useful ASAP please

Isomers are compounds with identical chemical formulas, but different structures. They are very important in air pollution chemistry, because even slightly different structures can evoke dramatic differences in chemical and physical properties.They are important because two isomers can have the same chemical formula, but have different chemical structures. The structure contributes to the properties of the molecule.Isomers: Structure and Function. ... Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are two main forms of isomerism: structural isomerism and stereoisomerism (spatial isomerism).That is, isomers contain the same number of atoms of each element, but have different arrangements of their atoms in space. A simple example of isomerism is given by propanol: It has the formula C3 H7 OH and occurs as two isomers: propan-1-ol (n-propyl alcohol; I) and propan-2-ol (isopropyl alcohol; II)They are important because two isomers can have the same chemical formula, but have different chemical structures. The structure contributes to the properties of the molecule.There are 3 different molecules (isomers) that have that formula (C3H8O).

Explanation:

im pretty sure its b

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
