Bleach is the generic term for substances that oxidize, or "bleach out," stains. There are a number of commercially available bleaching compounds. All of them are used to sanitize and brighten laundry, although some are used for whites and others for colored laundry. Oxygen-Based Bleaching Agen...
balance the equation using trial and error. This may mean it requires too many steps and the chemical equation is too complex to use this method, or that the equation is invalid (e.g. has 0 or non-integer coefficients). The algebraic method is likely better suited for bala...
Even when clandestine methamphetamine production ceases, the associated issues and long-term hazards do not end. Methamphetamine synthesis leaves behind hours of cleanup and testing, as well as the serious threat of potential health hazards.;Clandestine laboratories (Clan Labs) utilize chemicals hazardous...
The term "biobleaching" is sometimes also used to describe enzymatic bleaching. In both cases, the aim is to effect bleaching without the use of chl... Neil,Kirkpatrick - 《Water Science & Technology》 被引量: 0发表: 1991年 加载更多...
You’ll note they’re using the wordnitrate. Nitrates are specifically compounds containing the NO3–ion, but I think they’re using the term in a more general way, to suggest any nitrogen-containing compound (including urea and ammonia). And by the way, nitrates are different from the simi...
The percentage of carbon being used in feedstock as natural gas is very low as compared to the flows of the carbon cycle (about 0.002% of 9 GtC of anthropogenic emissions), but does illustrate the connections of chemical industries with carbon cycling in the long term. As the chemical ...

Every aspect of healthcare, exposure to chemicals is likely. For example, bleach that is used to clean can be harmful. Those who work in surgery may have to store specimens in formaldehyde which is also harmful. It is...
Create an equation for each element (Na, Cl, O, H, N) where each term represents the number of atoms of the element in each reactant or product. Na: 1a + 0b = 0c + 1d Cl: 1a + 0b = 1c + 0d O: 1a + 3b = 1c + 3d H: 0a + 1b = 1c + 0d N: 0a + 1b = ...
Create an equation for each element (Na, Cl, Fe, O, H) where each term represents the number of atoms of the element in each reactant or product. Na: 1a + 0b = 1c + 0d + 0f Cl: 1a + 0b = 1c + 0d + 0f Fe: 0a + 1b = 0c + 1d + 0f O: 0...
