Chapter 1: Problem 89

Which one of the following is a homogeneous mixture: milk shake, 14 -karat gold (made by melting gold and other metals together), fog, blood?

Short Answer

Expert verified

The homogeneous mixture among the given options is 14-karat gold.

Step by step solution

A milk shake is made by blending milk, ice cream, and flavorings together. Although the blending process may give the appearance of a homogeneous mixture, it may still have tiny particles of ice cream and other ingredients that are not entirely uniform. This makes the milk shake a heterogeneous mixture. #Step 2: Analyzing 14-karat Gold#

14-karat gold is made by melting gold and other metals together in a specific proportion (58.3% gold and 41.7% other metals, usually copper and silver). The melting process ensures that the gold and other metals are completely mixed together and distributed evenly throughout the material. This means that 14-karat gold is a homogeneous mixture. #Step 3: Analyzing Fog#

Fog is a mixture of tiny water droplets suspended in the air. The distribution of water droplets in fog is not uniform; they are dispersed unevenly and can vary greatly from one location to another. Therefore, fog is a heterogeneous mixture. #Step 4: Analyzing Blood#

Blood is a complex liquid that contains various types of cells (red blood cells, white blood cells, and platelets) suspended in a liquid plasma. Although blood may appear uniform, the composition of blood cells and plasma can vary within the blood sample. Thus, blood is a heterogeneous mixture. #Step 5: Identifying the Homogeneous Mixture#

Conclusion

Based on our analysis of the given options, we can conclude that 14-karat gold is the only homogeneous mixture among milk shake, 14-karat gold, fog, and blood.

Short Answer

Step by step solution

Fog is a mixture of tiny water droplets suspended in the air. The distribution of water droplets in fog is not uniform; they are dispersed unevenly and can vary greatly from one location to another. Therefore, fog is a heterogeneous mixture. #Step 4: Analyzing Blood#
