Question

Which of the following statements supports the idea presented?

A. True to all compounds, they no longer have the properties of the elements that make them up.
B. True to some compounds, it maintains the properties of the elements that make them up.
C. True in all elements, it maintains its properties even after it combines with other elements.
D. True to all elements, they have the properties after they are combined.

Answer 1

The correct statement is A, which indicates that compounds do not have the properties of the elements composing them, and therefore have distinct chemical and physical properties.

Step-by-step explanation:

The statement that supports the idea that compounds have different properties from the elements that compose them is: A. True to all compounds, they no longer have the properties of the elements that make them up. This is consistent with the Law of Conservation of Mass and the definition of a compound. Compounds consist of atoms of two or more elements combined in a fixed whole-number ratio, and through chemical reactions, these atoms can separate and recombine to form new substances, but the properties of the compound are generally distinct from those of its constituent elements. For example, water is a compound composed of hydrogen and oxygen, but it does not exhibit the properties of either gaseous hydrogen or gaseous oxygen.
