Answer (1)
Let's go through each statement one by one to understand the different types of mixtures mentioned:
Soy sauce and water is a uniform mixture because they mix completely.
When soy sauce is added to water, it dissolves completely, making the mixture uniform throughout. This type of mixture is known as a homogeneous mixture, where the components are evenly mixed.
Peas and carrots are not a uniform mixture because they remain separate.
Even when mixed together, peas and carrots can still be distinguished and are not uniform throughout. This indicates a heterogeneous mixture, where the components are not evenly mixed.
Glue and water is a uniform mixture because they mix evenly.
Glue, when dissolved in water, forms a solution where the mixture is consistent throughout. This property indicates a homogeneous mixture.
Spaghetti and meatballs is a heterogeneous mixture because the different components can be seen and separated.
In this mixture, the spaghetti and meatballs are distinct pieces that do not blend into a uniform substance, making it heterogeneous.
Salt and water is a homogeneous mixture because the salt dissolves completely in the water.
When salt dissolves in water, it evenly disperses throughout the solution, resulting in a uniform mixture.
Now, let's classify the following mixtures as homogeneous or heterogeneous:
Vegetable is a heterogeneous mixture.
Most vegetable mixes consist of different vegetables that maintain their individual properties and appearance, making the mixture non-uniform.
Halo-halo is a heterogeneous mixture.
This is a popular Filipino dessert with various ingredients that remain distinct, not blending into a single substance.
Air is a homogeneous mixture.
It is a mixture of different gases (like nitrogen, oxygen, etc.) that are mixed so thoroughly, they cannot be easily separated.
Table salt and water is a homogeneous mixture.
As previously mentioned, when salt dissolves in water, it creates a uniform solution.
Concrete materials are a heterogeneous mixture.
Concrete is composed of various materials like cement, gravel, and sand, which are not uniformly distributed, resulting in a heterogeneous mixture.
