Seawater mixture or pure substance

Write down the names of two elements, two compounds and two mixtures. Byju's Answer. Classify the following as element, mixture or compound: Sea water.

Seawater can be termed as homogeneous as well as a heterogeneous mixture because Seawater is basically a salt solution, hence, it is termed as homogeneous. As the concentration of salt in the sea can vary from place to place and it contains mud, sand and decayed parts of plants , hence, seawater is considered heterogeneous as well. Menu Categories.

Hydrogen and Oxygen H20 is the element compound of water. A salad is a mixture because you can take it apart. Even water and salt can be taken apart so its a mixture. A mixture is when two things have been put together and both chemical properties are still there. Where as wood and fire, the fire and wood turn into ash and some gases. So its not a mixture its a chemical reaction. There are some exceptions to this.

Some of these substances can be observed when the water in seawater evaporates and leaves behind salt. Water, H 2 O, is a pure substance, a compound made of hydrogen and oxygen. Although water is the most abundant substance on earth, it is rarely found naturally in its pure form.

This introduction to chemistry and seawater gives an overview of the concepts and activities explored in this unit and describes how these investigations build an understanding of ocean literacy. Seawater is a mixture made up of water and dissolved substances, including a variety of elements and compounds. With over chemical elements, a system is needed to organize the elements in a way that is meaningful and useful. The properties of elements and compounds are determined by their structures. The internal structure of an atom and the overall structure of a molecule both contribute to how atoms and molecules behave and react.

Seawater mixture or pure substance

Seawater is the most abundant resource on Earth! Seawater has evolved to what it is over the billions of years that oceans have existed on Earth. This chapter examines the physical and chemical properties of water and seawater. Figure 7. The water cycle. Components of seawater. Water is a polar substance. Each molecule of water has a negative charge associated with its oxygen, and a positive charge with it hydrogen Figure 7. This polar character is responsible for its properties cohesion and adhesion.
