The transformation below takes place by two distinct reactions. Intermediate A is formed in the first reaction and then this goes on to the product in the second reaction. Provide a complete curved-arrow mechanism for all steps of both reactions. CI O2N 2 O2N AICI3 2 NaOH, heat 2 3 Но `F HO O2N NO2 A NO2

Data and Report Sheet - Plastics Name Define a Polymer. Date Choose one of the polymers you tested. 1) Draw a representation of the structure. I 2) Briefly discuss its history and an interesting mechanical property and thermal property. 25

The Miller index for the figure is:

An extremely long cylindrical polymer is immersed in a liquid medium containing a high concentration of chemical A. If we need to solve for the concentration distribution of chemical A within the polymer, what is the interior boundary condition that we need to use?

Please do all parts if possible, I dont need explanation just answer, Thank you:   TRUE OR FALSE:  a) Glasses are usually harder than plastics but softer than silicon carbide and boron carbide b)  Any amorphous (lacking in long-range periodic order) materials, inorganic, organic, or metallic, formed by any techniques, exhibits glass transformation formation behavior are glasses  c) In general, the viscosity is low at the melting position of glass, and high at room temperature. d) In general, if the viscosity is very high at the melting position of the corresponding crystalline phase which would form the melt, it is much easier to form glass for this melt. e) The glass fiber is possible to have a tensile strength even larger than that for iron or structural steel. Therefore, in the practical applications, we should be able to use glasses for the same purposes of the iron or structural steel.

3- Empirical equations is the only method to estimate formation water resistivity. 4- The main purpose of the choke valves serve is to kill the pressure from reservoir to downstream pressure in the flow lines. 5- Calculation of the gamma ray index is the first step needed to determine the volume of shale.
