7. A student combines pure NaCl (sodium chloride) with pure DI water. The resulting is an example of:
a. homogeneous mixture b. heterogeneous mixture
c. pure substance d. suspension
I have chosen to discuss the terms heterogeneous and homogeneous for this week's discussion. I have some familiarity with these two words and most of my familiarity is in terms of cooking. There are a lot of examples of heterogeneous and homogeneous mixtures in the kitchen. A heterogenous mixture is one made up of multiple individual components, like a chocolate chip cookie or a bowl of cereal and milk. While the ingredients are blended together, they are still visibly separate. A homogeneous mixture is one that blends to the point of no individual components being visible. An example of this could be simple syrup or a pitcher of sweet tea or lemonade. The terms heterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree to which the materials are mixed together and the uniformity of their composition….just like as in the everyday usage of these terms. I feel like the similarities in the usage of…
