Why do you use the words heterogeneous and homogenous to describe mixtures?
Heterogeneous means that the mixture is not uniform in its composition. The different parts of the mixture are not spread evenly amongst each other. Sand and water is an example; the sand settles to the bottom. Homogeneous is the opposite, it means that the composition of the mixture is uniform and that there are equal numbers of any kind of particle in any area of the mixture. Salt water is a homogeneous mixture.
Is sea water a homogeneous mixture if you include sand?
No, if sand is included its heterogeneous.
Is olive oil a homogeneous mixture heterogeneous mixture?
Cooking oil is an example of a homogeneous mixture, because it has the same consistancy throughout. There is no need to shake it up before using. Shaking is necessary when the contents of a solution settle at the bottom of a solution, such as in Italian salad dressing.
Is iodine and ethanol a heterogeneous or a homogeneous?
Iodine is much more soluble in ethanol than in water, so it will usually form a homogeneous mixture. Of course, if you add more solid iodine than will dissolve in your quantity of ethanol at the temperature at which you are working, the excess solid will sink to the bottom. In that case, you have a heterogeneous mixture.
Is hot chocolate a compound or elements or mixture?
A mixture is a substance with a variable composition and is strong when the elements of that mixture bond to form a compound. Different compounds are air, coffee, tea etc... Coffee, for instance, can be weak or strong, and milk can be "whole" or low-fat. Though their molecular composition is variable, each of the mixtures described here is the same throughout: Such a mixture is described as homogeneous. Coffee is an example of a solution, a specific type of homogeneous mixture. Most homogeneous mixtures can be considered solutions. Heterogeneous mixtures contain regions that differ from one another. As an example, a glass of cold tea with undissolved sugar at the bottom is a heterogeneous mixture: the tea at the top is unsweetened or even bitter, whereas at the bottom, there is an overly sweet sludge of tea and sugar, however, if you heat up the tea it can become homogeneous.
Is the juice squeezed from an orange a substance or a mixture?
it is a heterogeneous mixture with the pulp and homogeneous without the pulp. Its also a suspension (with the pulp), since the pulp settles on the bottom upon standing.

Is vodka a heterogeneous or homogeneous mixture?
homogeneous, the same throughout. if it were heterogeneous, like tequila with a worm in the bottom of the bottle, it would be yuchy, and not vodka (legally, neutral distilled spirits = ethanol + water)
Is Italian salad dressing heterogeneous or homogeneous?
It depends on the components. If it's a mixture of oil and vinegar then it would be considered a heterogeneous, because the components aren't proportioned. Vinegar is more dense than oil so it will stay at the bottom. But, if it's a mixture like salt and water, then it would be considered a homogeneous because the mixture is a solution.
Is iodine and water homogeneous or heterogeneous?
They are homogeneous. But they are not a mixture, so they are a pure substance
Is Italian dressing a heterogeneous mixture a homogeneous mixture a element or a compound?
Rule of thumb to use, is if it can settle to the bottom of if it or you have to shake it; it is deffinitly heterogeneous.
Is sea water a homogeneous mixture if you include sand?
No, if sand is included its heterogeneous.

Is apple juice with pulp an heterogeneous mixture?
Orange juice without pulp is an example of a homogeneous mixture. The ingredients comprising the juice are evenly distributed throughout the mixture.
