Final Answer:
(a) The paper your textbook is printed on: homogeneous.
(b) Sand at the beach: heterogeneous.
(c) Jar of jelly beans: heterogeneous.
(d) Chunky peanut butter: heterogeneous.
Step-by-step explanation:
Homogeneous mixtures have uniform composition and appearance throughout, where the components are evenly distributed and not easily distinguishable. The paper your textbook is printed on is a homogeneous mixture as it is consistent in its composition throughout its surface.
Heterogeneous mixtures, on the other hand, have non-uniform composition and contain visibly different components that can be distinguished easily. Sand at the beach consists of various particles of different sizes and compositions, making it heterogeneous.
Similarly, a jar of jelly beans contains various colored and flavored beans that are distinctly different from one another, thereby making it a heterogeneous mixture.
Chunky peanut butter is also classified as a heterogeneous mixture due to its visibly discernible components, such as peanut chunks mixed within the smoother butter, creating an uneven distribution throughout the mixture.
