Answer a. Pure Water is not a mixture - it is a compound. Seawater is a mixture of water and salts, air is a mixture of gases and brass is a mixture (an alloy) of copper and zinc metals.

In a mixture are particles evenly mixed?
Sometimes They are in a a homogeneous mixture such as salt water or brass but are not in a heterogeneous mixture such as mud or oily water.
What is in the Ocean water?
Seawater is a mixture of various salts and water. Only six elements and compounds comprise about 99% of sea salts: chlorine, sodium, sulfur, magnesium, calcium and potassium. The relative abundance of the major salts in seawater is constant regardless of the ocean. Only the amount of water in the mixture varies because of differences between ocean basins because of regional differences in freshwater loss (evaporation) and gain (runoff and precipitation). The chlorine ion makes up 55% of the salt in seawater.
What is a suitable method for separating salt from seawater?
Allow the water to evaporate, leaving behind the salt would be effective for separating salt and water in a mixture.
Why would it be better to use the muddy puddle water than the seawater?
It is better to use the muddy puddle water than the seawater because of the salt
What is the most dense pure water at 1 degree Celsius pure water at 4 degrees or seawater?
Seawater, then pure @ 4 degrees C.
Which of the following is an example of a heterogeneous mixture water saltwater dirt or brass?
Dirt is a heterogeneous mixture.
Is seawater a pure substance or a mixture?
Seawater is a mixture. It is a combination of salt and water that is a homogeneous mixture. An example of a pure substance is either pure salt or pure sugar.
Is seawater a homegeneous mixture?
no, a homogeneous mixture is salt water, seawater has other particles in it like sand, bacteria, and other debris that can be seen making it heterogeneous
Is seawater an element?
No; seawater is essentially a mixture of water, salt and other substances such as sand.
Is water a mixture a compound or element?
Water is a compound. Seawater is a mixture containing salts as well as water.
Is seawater is mixture?
yes
is seawater a compound mixtue or element?
sodium is an element and also can be an ingredient of a compound. Sea water contains sodium(salt). They say rainwater is acidic, and if it is then the seawater also contains a form of acid, which is a compound to many types of solutions. Answer to your question: BOTH
Why is seawater considered a mixture whereas distilled water is considered a compound?

acetic,water,soft drinks,glass
Is the oceans a mixture or pure substance?
The ocean would be considered a mixture of water, salt, sand, and plant and animal life, among other things. Seawater would still be considered a mixture of H2O, NaCl, Mg, S, K, Ca, and Br among other things. For a complete list of the chemical composition of seawater, see the following link. http://www.seafriends.org.nz/oceano/seawater.htm#composition
Is seawater a homogeneous mixture or heterogeneous mixture explain?
seawater is a homogeneous mixture. The water being the solvent and the salt being the solute. A heterogeneous mixture is mixed but not as thoroughly as a homogeneous mixture. None of these though are chemically combined, none are compounds. (hence mixture)
