Milk and oatmeal homogeneous or heterogeneous element or compound why
Answers 1
A compound of milk and oatmeal is an example of a heterogeneous compound. Oatmeal does not dissolve into milk and can still be separated between milk and oatmeal.
Heterogeneous is a mixture of two or more substances with an uneven composition. This chemical mixture is the opposite of a homogeneous mixture in which the elements in it are indistinguishable. This is what distinguishes it from a homogeneous mixture.
The components of the constituent substances in a heterogeneous mixture have different properties and are not mixed evenly. This makes heterogeneous mixtures have a clear boundary between one substance and another.
There are two types of heterogeneous mixtures:
- Suspension
A suspension is a heterogeneous mixture consisting of a solid and a liquid or gas, in which the solid is insoluble. Suspension that is left for a long time will cause a precipitate. Examples include a mixture of water and coffee, a mixture of sand and water, and cough syrup.
- Colloid
Colloid is a heterogeneous mixture consisting of two or more constituent substances, in which one of the substances spreads over other substances but not evenly. For example coconut milk, milk, cheese, fog, clouds, smoke, paint, to oil granules in margarine.
Heterogeneous mixtures have 4 properties, namely:
- Contains Two or More Ingredients
Heterogeneous mixtures contain at least two ingredients or phases, it can be more than two. The materials and phases can be two solids, two liquids (emulsions), or two gases. It can also be a mixture of solid and liquid (suspension), gas and liquid (aerosol), or gas and solid (smoke).
- Chemical Identity Doesn't Change
Two different substances mix, but physically they remain separate. One substance with another substance still maintains its respective chemical identities and does not change.
- Different Samples
If we sample from a small part of the mixture, the composition may be different from the sample we take from another part. So, in a mixture, the composition of one part with another part can be different.
- Separable
Heterogeneous mixtures can usually be separated again. For example, in a mixture of water and sand, the water and sand can be separated if the sand has formed a precipitate.
