C) Sodium
D) Magnesium

Answer 1

Sodium is the soft, highly reactive metal that includes compounds such as table salt, lye, and baking soda.

Step-by-step explanation:

The soft, highly reactive metal whose compounds include table salt, lye, and baking soda is sodium (Na). Sodium belongs to Group 1, known as the alkali metals, which also includes lithium (Li), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

Sodium compounds, such as table salt (sodium chloride), lye (sodium hydroxide), and baking soda (sodium bicarbonate), are commonly used in daily life. Sodium and potassium are the seventh and eighth most abundant elements in Earth's crust respectively.
