Comparing the profile of ciprofloxacin with its intermediates, it was found that A was the first intermediate to form during ciprofloxacin degradation, and the remaining four intermediates (B-E) appeared gradually based on their polarity with compound A during the photodegradation in the presence of ...
Factors that affect the rate of diffusion include all of these but not molecules: a. size. b. polarity. c. charge. d. isomer. e. concentration. An increase or decrease in the density of a chemical substance in an area is called?
A sulfuric acid solution, which has a pH of 6 or an acetic acid solution that has a pH of 4. Answer) An acetic acid solution with the pH of 4. Because the lower the pH, the more acidic the solution is. (Sulfuric acid disassociates completely in water. That is why it is a “...
In one polymorph the molecule has a slightly twisted conformation, but is linear, planar in other two polymorphs [16]. In the solution, the geometry of the enolone fragment is attributed to the inherent disorder of the local environment, which solvates one of the basic sites better than the...
An administrative Open has been initiated, but the lower layer is still unavailable (Down). The Restart timer is not running in the Starting state. When the lower layer becomes available (Up), a Configure-Request is sent.[1] starting () { if (event) { = UP: irc(event); //action ...
(i) The H/F/H/O distances are determined by the proton acceptor group polarity of the fragment in question. The shortest H/O distances are formed by the O]C group. (ii) The H/F distances of aromatic uorine (F–CAr) are similar to the H/O distances of...
water into oxygen and hydrogen have been made by the use of water-soluble porphyrins in artificial systems.2 The reason why the water-soluble sensitizers are used for decomposition of water is that these sensitizers have good affinity to the hydrophilic reaction field and electron carriers in the...
Name the material used for making a fuse wire. Give a reason. What does the valve in the water circuit represent in your electric circuits? Why should the wires connecting the resistances and the bridge need to be as short as possible?
Cellular heterogeneity in cancer represents a significant challenge. In order to develop effective and lasting therapies, it is essential to understand the source of this heterogeneity, and its role in tumor progression and therapy resistance. Here, we c
