(a)
Expert Solution
Answer to Problem 1QAP
The difference between oxidation and reduction electrochemical reactions is explained as below:
Explanation of Solution
Electrochemical reaction is the process that involves electron transfer between two substances mostly a metal and an electrolyte. It includes oxidation and reduction reactions that occur simultaneously. Oxidation reaction involves loss of electrons by a molecule or an atom to form a cation. This causes increase in oxidation state. Reduction reaction involves gain of electrons by an atom to form an anion. This causes decrease in oxidation state. Thus, the basic difference between oxidation and reduction electrochemical reaction involve loss and gain of electrons in an atom, respectively.
(b)
To determine
To explain:
Which reaction (oxidation and reduction) occurs at anode and which at the cathode?
(b)
Expert Solution
Answer to Problem 1QAP
The reaction (oxidation and reduction) occurs at anode and at the cathode is explained as below.
Explanation of Solution
Oxidation and reduction reactions occur at electrodes. Anode refers to negative electrode and cathode refers to positive electrode. Oxidation takes place at the anode as it involves loss of electrons. Reduction takes place at the cathode as it involves gain of electrons.

Figure 1 shows the plan view of an Exhibition Hall with dimensions L1 x L2. The structure is to be constructed in a coastal region which will be exposed to mostly mild environmental conditions and should provide a 1.5-hour fire resistance. It is known that the underlying foundation soil contains sulphate and other organic compounds. The layout of the structure consists of portal frames which are spaced evenly along the L2 direction. The frames are to support a slab of thickness (t) that will cover the full area of the hall plan. The dead and live loads applied on the slab are G and Q (kPa), respectively.

Antibiotic P is a compound secreted by microorganism A during the stationary phase. To produce P, substrate S is required. The growth of microorganism A follows the Monod equation, with a maximum specific growth rate $\mu_m = 1 h^{-1}$ and a half-saturation constant $K_s = 700\ mg/L$.The pilot process uses a chemostat with a working volume of $1000\ L$. In this chemostat, the outflow is processed to separate microorganisms, which are then concentrated tenfold and recycled.

- Create a sparse FAT filesystem image named recovery. img using mkfs fat. You can choose the size of the filesystem as long as it is less than 2GB. Copy 3 files of your choice into the filesystem, e.g., by using mcopy or by mounting the filesystem and using cp. Note that the size of each file must be between 4KB and 6KB. Pick one of the files (say foo.jpg) and identify which byte offsets and which clusters are used to store it using mshowfat. The ranges that you give should be inclusive of the last byte/cluster. Record your answers in a file named recovery.txt with a table of this form: FILENAME: foo.jpg | byte offset range | cluster range 0x04200-0x047ff 0x06400-0x0651c 2-4 | 19-19 | Now find the part of the File Allocation Table that corresponds to your choice of file.
