Question

multiple-choice question what is another example of a pure substance that falls under this category? h₂o + nacl, salt water; c₆h₁₂o₆, sugar; air

Explanation:

To determine a pure substance example, we recall that pure substances are either elements or compounds. \( \ce{C6H12O6} \) (sugar) is a compound (a pure substance), while \( \ce{H2O + NaCl} \) (salt water) and air are mixtures. So \( \ce{C6H12O6} \) (sugar) is a pure substance.

Answer:

\( \ce{C6H12O6} \), sugar
