sucrose (c₁₂h₂₂o₁₁) dissolves easily in water (h₂o) to produce an aqueous sugar solution. what is the correct description of these two substances?
○ sucrose and water are both elements because they exist as a solid and liquid when separate and form an aqueous solution when combined.
○ sucrose is an element, and water is a compound because the sucrose dissolves in the water.
○ sucrose is a compound, and water is an element because the sucrose dissolves in the water
○ sucrose and water are both compounds because both substances are made up of more than one type of atom.

Explanation:

To solve this, we recall the definitions: An element consists of only one type of atom, while a compound is made of two or more different atoms chemically bonded. Sucrose ($\ce{C_{12}H_{22}O_{11}}$) has C, H, O atoms; water ($\ce{H_{2}O}$) has H and O atoms. So both are compounds. Let's analyze each option:

• First option: Elements are single - type atoms, but sucrose and water have multiple atom types. Wrong.
• Second option: Sucrose has multiple atom types, so it's not an element. Wrong.
• Third option: Water has H and O, so it's a compound, not an element. Wrong.
• Fourth option: Both sucrose (C, H, O) and water (H, O) are made of more than one type of atom, so they are compounds. Correct.

Answer:

D. Sucrose and water are both compounds because both substances are made up of more than one type of atom.
