Question

which of the following is an example of a heterogeneous mixture? chocolate milk bronze air salt water

Explanation:

A heterogeneous mixture has visibly different substances or phases. Chocolate milk is a homogeneous mixture (uniform composition). Bronze is an alloy (homogeneous). Air is a homogeneous mixture of gases. Salt water is a homogeneous mixture (salt dissolved uniformly). But if we assume there might be some undissolved particles (though typically salt water is considered homogeneous in basic chemistry contexts, but if in a non - ideal case with sediment), but among the options, if we consider the general understanding: Wait, no - actually, let's re - check. Wait, no, hold on. Wait, no, in reality, chocolate milk (if made by powder, and if not fully dissolved) could be heterogeneous. But in a well - made chocolate milk (powder fully dissolved), it's homogeneous. But among the options: Bronze is a solid solution (homogeneous). Air is a gas mixture (homogeneous). Salt water (if salt is dissolved) is homogeneous. But if the chocolate milk has undissolved chocolate particles (like in a quick mix), then it's heterogeneous.

Answer:

Chocolate milk
