is salt water an element compound homogeneous or heterogeneous?
87526
Saltwater is a homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound. Oxygen, a substance, is an element.

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent.

In a homogeneous mixture, the different parts cannot be seen. A solution of salt dissolved in water is an example of a homogeneous mixture. When the salt dissolves, it spreads evenly through the water so that all parts of the solution are the same, and you can no longer see the salt as being separate from the water.

A homogeneous mixture is a mixture in which the composition is uniform throughout the mixture. The salt water described above is homogeneous because the dissolved salt is evenly distributed throughout the entire salt water sample. ... The amount of salt in the salt water can vary from one sample to another.

Salt water is water that contains a certain amount of salts. ... Salt water can be found everywhere on the surface of the earth, in the oceans, in rivers and in saltwater ponds. About 71% of the earth is covered with salt water. Freshwater is water with a dissolved salt concentration of less than 1%.

Perhaps the biggest difference is in the name itself. Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent.

Heterogeneous compound When sugar is dissolved in water it produces a homogeneous mixture; the dissolved sugar is uniformly spread out in the water. The same with dissolved salt.

Ordinary table salt is called sodium chloride. It is considered a substance because it has a uniform and definite composition. All samples of sodium chloride are chemically identical. Water is also a pure substance.

By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. ... Oil and water do not mix, instead forming two distinct layers called phases. The oil phase is less dense than the water phase and so the oil floats on top of the water.

It is considered a pure substance because it has a uniform and definite composition. All samples of sodium chloride are chemically identical. Water is also a pure substance.

Because our oceans have lots of dissolved sodium (Na), salt can easily form out of drying seawater. ... As the water evaporates, it leaves behind the sodium (and other elements, like chlorine). When enough water has evaporated, sodium and chlorine like to bond together to form solid halite (salt).

A pure substance consists of a single element or compound. Iron is formed only of iron (Fe) atoms; table salt is formed only by sodium chloride (NaCl) molecules. A mixture, however, is made up of different compounds and/or elements. When salt is added to water to make saltwater, it becomes a mixture.

Salt water is a type of solution in which salt is mixed into water. Salt water is a homogeneous solution, because once mixed in, you can no longer see the salt. There are two parts to a solution: the solute and the solvent.

A mixture in which its constituents are distributed uniformly is called homogeneous mixture, such as salt in water. A mixture in which its constituents are not distributed uniformly is called heterogeneous mixture, such as sand in water.

Saltwater contains salt, or sodium chloride. Freshwater may contain small amounts of salt, but not enough to be considered saltwater. Ocean water has an average salinity of 3.5 percent. This means that there are 35 grams of salt dissolved in every liter of seawater.

Saltwater acts as if it were a single substance even though it contains two substances—salt and water. Saltwater is a homogeneous mixture, or a solution. ... Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound.

Ocean water has a high salinity, which is the amount of salt dissolved in water. Besides the high concentration of sodium chloride, ocean water also contains chemicals, such as magnesium, sulfate, calcium, and potassium, as well as dissolved gases, including nitrogen, oxygen, and carbon dioxide.
