Question

1. which of the following is an example of a homogeneous mixture? (3pts)

□ sugar, c₁₂h₂₂o₁₁
□ chocolate chip cookies
□ caffeine, c₈h₁₀n₄o₂
□ stainless steel
□ hydrogen

Explanation:

A homogeneous mixture has a uniform composition throughout. Sugar ($\text{C}_{12}\text{H}_{22}\text{O}_{11}$) and caffeine ($\text{C}_{8}\text{H}_{10}\text{N}_{4}\text{O}_{2}$) are pure compounds, not mixtures. Chocolate chip cookies are heterogeneous (components are visibly distinct). Hydrogen is a pure element. Stainless steel is an alloy (mixture of iron, carbon, and other metals) with uniform composition at the microscopic level, making it a homogeneous mixture.

Answer:

$\square$ stainless steel
