Answer:
The answer is: Applied Chemistry
Explanation:
Apllied Chemistry is a branch of Chemistry that deals with the application and use of Chemistry principles and theories to answer a specific question or solve real world problems. It is aimed at taking Chemistry knowlege from the classroom to the real world. In this example, Marie noticed that a problem had arisen, and that is corrosion of metals, and she set out to apply the principles of Chemistry to make a paint formulation that prevvents corrosion, not just on paper with a bunch of formulas and calculations, but translated into a real life substance. On the other hand, pure Chemistry is the theoretical aspect of Chemistry, where the result of the researches are purely for knowlege and not for real world application.
Answer:
B .Through testing a theory about the physical world
Explanation:
<span>The correct answer is b.
