Seawater is neither a compound nor an element but a mixture including much dissolved solid and usually microorganisms as well.
Seawater is neither an element nor a compound but rather a mixture.
Water is a compound. Seawater is a mixture containing salts as well as water.
compound
The foam of the sea is a mixture, as is seawater itself. The foam differs from the seawater by containing dispersed as well as dissolved air. The dispersed air forms the bubbles of the foam.
The most abundant compound in seawater is sodium (salt). Symbol is Na and atomic number is 11.
Magnesium
Seawater is water (H2O which is a compound) containing soluble compounds but also insoluble materials. We can consider, with approximation, that the seawater is a homogeneous solution.
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
Water is a compound. Seawater is a mixture containing salts as well as water.
It's a solution; water with dissolved solids.
compound
Seawater is a mixture - a compound is a chemically bonded substance involving more than one element.
The foam of the sea is a mixture, as is seawater itself. The foam differs from the seawater by containing dispersed as well as dissolved air. The dispersed air forms the bubbles of the foam.
No, water is a compound of hydrogen and oxygen. And filtered sea water would still have many other impurity's in it as well
A trace element is considered is a specific element that contains less than 100 parts per million in a sample. In this case, the sample is seawater. According to my understanding, the presence of iodine is very limited in seawater. There is only 0.05 parts per million of iodine in seawater. As such, iodine is considered a trace element in seawater.
The most abundant compound in seawater is sodium (salt). Symbol is Na and atomic number is 11.
Magnesium
No; seawater is essentially a mixture of water, salt and other substances such as sand.
