Fuller’s earth is actually a catchall term for a chemically diverse set of absorbent clay minerals capable of absorbing their weight in water. Fuller’s earth litter can get rid of some of the ammonia odor by trapping the positively charged ammonium ions that are formed when water in urine penetrates the ammonia. To improve odor control the cat litter used things such as baking soda to absorb the smells‚ and antibacterial agents to kill odor- causing bacteria. The only thing wrong with Fuller’s earth

contains appreciable quantities of urea but almost no ammonia. Upon standing‚ urine specimens develop the odor of ammonia. Explain why this odor develops. The odor develops because of the bacteria present. The bacteria usually increase the pH as they break down urea to ammonia. Another factor involved is high acid levels. Ammonia release can occur when the body is too acidic. Ammonia smell is from the body excreting large quantities of ammonia‚ a very alkaline substance‚ to try to maintain a proper

and treated with ammonia gas. The gas reacts with the water in the meat to form ammonium hydroxide‚ reducing acidity and killing pathogens.” In the case of pink slime‚ or “Lean Finely Textured Beef”‚ the main focus are the beef trimming along with anhydrous ammonia and the use of ammonium hydroxide. The biggest concern for the beef trimming were foodborne illness such as E.coli or salmonella. Anhydrous Ammonia were used as an antimicrobial intervention however‚ anhydrous ammonia is also used to

Describe what happens at the molecular level during evaporation. Evaporation is the process by which molecules undergo a change in state from a liquid to a gas. At a molecular level a molecule needs a set energy level to evaporate. When molecules collide they transfer energy. Eventually one molecule will get the energy required to change state

reason for the definitions is because aquaponics is a mixture of aquaculture and hydroponics. It is the same concept as hydroponics. The plants roots are submerged in water with fish waste and ammonia that are added is the part of the system that is like aquaculture. The plants absorb and suck up all the ammonia and turn them into nitrites and then into nitrogen‚ which then helps the plants because the plants need nitrogen in order to live. The aquaponic system consists of two main parts the reservoir
