Answer:
USe this Nernst equation and find your required answer
Explanation:
E = E0 - [0.0592 /n ] log [Cd+2]/[Co2+]
Wher Eo is +0.120 V
[Cd+2] =0.1
[Co2+] = 0.001
n is number of electons transfered int he process and in your case it is = 2
E= 0.120- 0.0296 * log 100
= ........ V
increase Polymer strain to failure is given below.
Explanation:
- Strain to failure gives the measure of how much the specimen is elongated to failure. By this it means that, it you have strain to failure of 3% measured in specimen of length 100 mm, the material will fail when it it elongated 3 mm, as experimented in tensile test. Therefore, for a material with higher strain to failure rate, the ductility is higher and tensile strength is lower.
- Tensile strength means the maximum mechanical stress (i.e. applied force divided by (initial) cross-section area of the specimen tested) during a tensile test, which is not directly correlated to the deformability or strain at failure or break since the tensile strength also is affected by the stiffness of the material. Therefore a ductile material might deform on a lower mechanical stress level than a stiffer one (this is the usual case), meaning its tensile strength is lower although its deformability is higher.
- Therefore, for a material with higher strain to failure rate, the ductility is higher and tensile strength is lower.
Answer:
Sea ice
Explanation:
Sea ice has a much higher albedo compared to other Earth surfaces
Answer:
False
Explanation:
Laboratory synthesis of aspirin is done by the acetylation of salicylic acid with the help of acetic anhydride .
As , the acid anhydride is very sensitive to moisture , as it can hydrolyze into two molecules of acids,
Hence , the reaction involving acid anhydride are conducted in anhydrous solvents .
Hence ,
if water is present in the glassware then , some of the acetic anhydride is wasted , Which in turns reduces the yield than that expected .
