Which of the following mixtures is homogeneous? A. rocky road ice cream C. soft drinks B. fruit salad D. spaghetti
The Correct Answer and Explanation is:
Correct Answer: C. soft drinks
Explanation:
Mixtures can be classified into homogeneous and heterogeneous mixtures based on how uniformly their components are distributed.
A homogeneous mixture is one in which the components are evenly distributed throughout the mixture. It has a uniform appearance and composition, meaning you cannot distinguish one part from another. A good example of this is soft drinks. When unopened and carbonated, soft drinks like soda consist of dissolved gases, sugars, flavors, and coloring agents, all uniformly mixed. If you take a sample from any part of the drink, it will have the same composition.
On the other hand, heterogeneous mixtures are those where the components are not uniformly mixed. You can often see and pick out the different parts of the mixture. Let’s look at the other options:
- A. Rocky road ice cream: This contains nuts, marshmallows, and chocolate chips mixed into the ice cream. These ingredients are not evenly distributed, and you can clearly see and taste the different parts. This makes it a heterogeneous mixture.
- B. Fruit salad: This is an obvious example of a heterogeneous mixture. You can see the individual pieces of fruits such as apples, bananas, and grapes, and each bite may contain a different combination.
- D. Spaghetti: This also falls under heterogeneous mixtures because you can distinguish the pasta from the sauce and other toppings like meat or vegetables. The distribution is not uniform, and you can physically separate the components.
In summary, soft drinks (option C) are the only homogeneous mixture among the choices because they appear consistent and uniform throughout, assuming the drink has not been opened or allowed to go flat.
