Question

____, a powerful nonmental thats used to bleach wool and straw, is a brittle, lemon-colored, crystalline solid.

answer options:
select one of four

sulfur
oxygen
nitrogen
phosphorus

Explanation:

We need to identify the non - metal used for bleaching wool and straw, with a brittle, lemon - colored, crystalline solid appearance.

• Oxygen is a gas at room temperature, so it can't be the answer.
• Nitrogen is also a gas at room temperature, so it is not the correct option.
• Phosphorus has different allotropes, but its common forms do not match the description of being used for bleaching wool and straw with a lemon - colored, crystalline solid appearance.
• Sulfur is a non - metal, it is a brittle, lemon - colored (yellow) crystalline solid, and it can be used in bleaching processes for materials like wool and straw.

Answer:

Sulfur
