Heterogeneous means that there are different compounds in a sample. Heterogeneous is a term used with mixtures and the way I like to think about it is:
If you have cheerios, apple jacks, and coco puffs in a bowl you have a heterogeneous mixture because you can physically separate the cereals from each other. If you can not physically separate out the components, it is not a mixture.
A heterogeneous mixture is a mixture in which you can see more than one phase.
homogeneous
Fruit salad is a heterogeneous mixture because it contains different components that can be visually distinguished, such as pieces of various fruits.
No, a mosquito is an organism and not a mixture. A heterogeneous mixture is a combination of different substances that are not uniformly distributed.
Heterogenous, because the components are unevenly mixed throughout. However, smooth salsa is more homogeneous, and chunky is more heterogeneous. ;)
River water is generally a heterogeneous mixture based on the different components it is carrying. Water by definition is not an element, rather a molecule comprised of them.
A mixture is two or more substances combined together with actually reacting chemically. So, be it homogeneous or heterogeneous, a mixture is a mixture if it fits this definition.
Ca is an element. It is a pure substance, which, by definition, is homogeneous matter, but is not a mixture.
hetergeneous
A flower is a heterogeneous mixture.
The separation of constituents in a heterogeneous mixture creating a non-uniform distribution of concrete mixture.
If you mean salt & pepper in the same container, I would say heterogeneous mixture, but salt by itself would be a compount (NaCl?), while pepper would likely be a homogeneous mixture (milled black pepper).
Heterogeneous mixture.
Sand+salt: a heterogeneous mixture.
