According to the content covered in your study guide and video lessons, what are models used for in Chemistry?
I- To attempt to explain and define something that we do not have the ability to see without the use of instruments or that is too complex.
II- To constitute an important part of Chemistry, as they are a didactic resource used to explain everything that occurs at the submicroscopic level.
III- To share the results of scientific research.
IV- The proposed model is not always faithful or perfectly describes what is being studied, and may later be refuted or considered limited.
a. Only I, II, and III are correct.
b. Only I and III are correct.
c. Only I is correct.
d. All statements I, II, III, and IV are correct.
e. All statements are incorrect.

A resposta correta é a alternativa "a. Apenas I, II e III estão corretas". Os modelos são usados na Química para tentar explicar e definir algo que não temos a capacidade de ver sem o uso de instrumentos ou que é muito complexo. Eles são uma importante ferramenta didática para explicar tudo o que ocorre no nível submicroscópico. Além disso, os modelos propostos nem sempre são fiéis ou descrevem perfeitamente o que está sendo estudado, podendo ser refutados ou considerados limitados. No entanto, eles são uma forma importante de compartilhar os resultados da pesquisa científica.
