An element, such as gold or silver. Vitamins Any of various fat-soluble or water-soluble organic substances that are essential in minute amounts for normal growth and activity of living organisms. They are synthesized by bacteria and plants and are obtained by animals chiefly in their diet. Mi...
Question: What are the products of electrolysis of water? Electrolysis: Electrolysis is the process by which electrical energy is used to split compounds. The word electrolysis was first introduced to the scientific lexicon by Michael Faraday close to 200 years ago and is still in use. ...
HOCI and OCI both dissolve in water. These two chemicals kills bacteria and they do that by attacking the lipids in the cell. HOCI is able to oxidise (loss of electrons) organisms in seconds and OCI is able to oxidise (loss of electrons) organisms in about 30 minutes. This means that...
Fig. 1. Sketch showing the total chloride profiles from a concrete element submerged in sea water at Solsvik field station (Norway) for 16 years. The concrete was made with a Portland composite cement containing 4 % silica fume and 19 % fly ash [2]. On the left, typical features of th...
What are the components found in wheat that make it have the special characteristic of being sticky? Summarize the unique features of aflatoxins and ergot. Name the four emergent properties of water. Why do you think that some substances dissolve easier in one type of liquid than in another?
Thus, all these reactions are considered reactant-favored, and for purposes of predicting water solubility, we ignore the fact that some ions are formed. Remember that the intact weak acid or weak base molecules may themselves dissolve in water through hydrogen bonding. (See section b) (i) ...
