I’m not sure whether he deems his argument to imply that there is no water in the sea either; he doesn’t say. I came to a different conclusion in Needham (2006b), and by parity of reasoning, I would say that the sea is a mixture in which water is to be found. In general, ...
using a magnet to separate iron filings from a mixture of iron filings (dark grey colour) and sulphur (yellow colour).Note: This is one of a series of simple pages introducing key concepts in introductory chemistry. Other pages in this section include elements, mixtures and compounds and ...
How does salt water in a pool work? What is a salt chlorine generator for a pool? In this article, we discuss salt chlorinators (also called salt chlorine generators) and how they work.
(H2O)molecule, which is made up of two hydrogen atoms and one oxygen atom. Both hydrogen and oxygen aregasesat room temperature and normal atmospheric pressure. But when they combine to form water, the chemistry changes and the resulting substance is aliquidat room temperature and normal ...
A solution of salt water, for example, will have a different freezing point depending on how much salt is dissolved in the water. 3.What is one basis for classifying a mixture as homogeneous or heterogeneous? A. Whether its component parts are the same type of matter B. Whether its ...
CARBOXYMETHYLCELLULOSE SODIUM SALT is usually sold in powder form and needs to be dissolved in water and stirred until a gel-like substance is formed before use. It can be added in appropriate amounts to food, medications, or cosmetics, and stirred until well mixed. This is a brief ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...

If a lot of salt is mixed with water, it won't all dissolve. In this situation, dissolution proceeds until there are too many sodium and chlorine ions in the mixture for water to win the tug-of-war with undissolved salt. The ions get in the way and prevent the water molecules from ...
Technically, the term "mixture" is misused when a recipe calls for you to mix, for example, flour and eggs. Achemical reactiondoes occur between those cooking ingredients. You can't undo it. However, mixing dry ingredients, such as flour, salt, and sugar, does produce an actual mixture. ...
