The contributions made by scientists that played the greatest role in expanding the study of chemistry are:

1. Michael Faraday's development of the electromagnetic rotary device and his work on electromagnetism had a significant impact on the field of chemistry as it laid the foundation for the electric motor. This innovation enabled the study of electricity and its relationship with chemical processes.

2. Dmitri Mendeleev's table of elements, also known as the periodic table, was a groundbreaking contribution that revolutionized chemistry. By organizing the known elements based on their atomic properties, he discovered patterns and left open spaces, which eventually led to the prediction and discovery of new elements. Mendeleev's periodic table is still widely used today as a fundamental tool in the study of chemistry.

It should be noted that George Washington Carver and Marie Curie, while they made important contributions in their respective fields, their impacts were more significant in other areas rather than directly expanding the study of chemistry.

3. George Washington Carver, an agricultural scientist, collaborated with chemists, industrialists, and agriculturalists to find practical applications for chemical inventions and innovations in the agricultural industry. While Carver promoted the use of chemistry to improve society, his contributions were more focused on agricultural advancements rather than expanding the study of chemistry itself.

4. Marie Curie, a physicist and chemist, is renowned for her work in radioactivity and the discovery of polonium and radium. While her discoveries and research had a tremendous impact on our understanding of the atomic nature of matter, her specific contributions did not directly expand the study of chemistry. However, the application of her discoveries led to advancements in fields such as medicine and industrial chemistry, including the development of glow-in-the-dark paints.

Therefore, the two scientists, Michael Faraday and Dmitri Mendeleev, made the greatest contributions in expanding the study of chemistry, while George Washington Carver and Marie Curie made important contributions in other fields.
