Question

1. read the following sentences: \when the atoms of a specific substance are regrouped, a new substance is formed with often vastly different properties from the original substance. occasionally something completely harmless, or even necessary, can become dangerous or lethal when its molecules (a grouping of two or more atoms) are regrouped.\ what does the word properties mean above? a. extremely large amounts b. places where experiments are done c. qualities or characteristics d. elements or compounds

Explanation:

The word "properties" in the context of substances refers to their qualities or characteristics. When atoms are regrouped to form new substances, the new substances have properties (qualities/characteristics) that can be very different from the original ones. For example, hydrogen and oxygen (original substances) combine to form water (new substance), and water has different properties (like being a liquid at room temperature, having a certain density etc.) compared to hydrogen (a highly flammable gas) and oxygen (a gas that supports combustion).

Answer:

C. qualities or characteristics
