Question

stan is researching a new insecticide that will be less toxic to birds and small mammals that may come in contact with it.
a neither applied nor pure chemistry
b applied chemistry
c pure chemistry

Explanation:

Applied chemistry focuses on using chemical knowledge for practical applications (like developing new insecticides with specific properties). Pure chemistry is about understanding chemical principles without immediate practical use. Stan's work on a new insecticide for a practical purpose (less toxic to animals) fits applied chemistry. Option a is incorrect as it is a practical application. Option c is incorrect as pure chemistry is theoretical, not applied to developing a product.

Answer:

b. applied chemistry
