Why are weathering and erosion considered destructive forces? Why does sugar dissolve in water? Why can water dissolve many substances? Why are hydrocarbons extremely flammable? Why is ammonia a base? Why is phenol a weaker acid than ethanoic acid (acetic acid)?
weak acid. A base is the one that donates an electron pair. If it readily donates the electron pair, then it is a strong base, otherwise a weak base. Ammonia has a lone pair of electrons on the nitrogen atom and can donate this electron pair. Hence, ammonia is considered as a base....
So why is one good for you like the complex carb and one not as good like the simple carb? More about this a little further down in the article but, it depends on their chemical makeup. The simpler the carb is considered bad for all it contains is sugar....
Universal pH paper is a special type of paper that contains an indicator that can change color when exposed to an acid or base. The colors that the paper can change, depending on the pH, include red, yellow, green, blue, or purple....
In particular, the flap can be considered to be in an ‘open’ conformation as opposed to the ‘closed’ conformation in KAU. In contrast, in BPU crystallized in the presence of PPD, the flap is in the ‘closed’ conformation, very similar to that found in native KAU ( Figure 2 ). ...
The now defunct Chinese space station Tiangong-1 is en route to crash into Earth – completing its "atmospheric reentry phase". While experts have been aware that this would happen for more than a year, there has been huge uncertainty around the exact ti
CT refers to tillage operations considered standard for a specific location and crop, in which the crop residues are usually buried and soil inversion is generally involved [92]; it is usually considered a base for determining the cost-effectiveness of erosion control practices. In England, 42% ...
[26]. This is why the triel centers are characterized by strong electrophilic properties, since interacting with electron donating ligands, they may fulfill the octet rule. However, it was found that the triel centers differ significantly if the individual elements are considered [23]. For ...
Its use could indeed be considered superior compared to blood because it is non-invasive, simple, and without requirement of a specially trained operator. Besides that, urine samples could be abundantly supplied (the average value for adult is 1.5–2.0 L per day) [31]. Along with elevated ...
