The CabECO (R) cell is a PEM electrolyzer; that is to say, one in which anode and cathode are connected through a PEM membrane. Since ozone production on the electrolyte is important and depends on the composition of the liquid, attention must be paid to the electrochemical production of ...
Explain the differences between temporary, semi-permanent, and permanent emulsions. Give an example of each. Explain how to distinguish between anode and cathode. (a) Explain what characteristics of metalloids are more like metals. (b) Explain what characteristics of metalloids are...
However, that really applies only to things likeelectrolysis(passing electricity through a chemical to split it up). Batteries are like electrolysis going backwards (they split up chemicals to make electricity) so the terms anode and cathode are switched around. Okay? To avoid confusion, I suggest...
Explain how to distinguish between anode and cathode. What is graphite? Is it conductive or not? What is the difference between Democritus and Dalton? Elaborate thoroughly. What transitional metal might be suitable to manufacture indestructible spectacle frames? ...
(silver and lead) can be removed byfiltering/centrifugation/decantingan ionic equation; i.e.Zn+2Ag+→Zn2++2Ag or Zn+Pb2+→Zn2++Pb allow: anytwo correct half equations(iv) cathodelabelledcarbon/zinc/platinum;zinc deposited at cathode; oxygen formed(at anode);(electrolyte becomes)sulfuric ...
When the current is switched on, negatively-charged DNA fragments willmigrate towards the anode/positively-charged electrode;;5. Rate of movement is inversely proportional to length/size/molecular weightof the DNA fragment;6. Longer length of DNA fragments encounter more resistance, travel moreslowly...
P side of the pn junction is connected to the anode and consists of holes. At the same time, the n side of the pn junction is connected to the cathode and consists of excess electrons. The cathode is negatively charged, while the anode is positively charged and carries an e...
There's a glass top panel and a glass base (gray). The anode electrodes (green) are at the bottom, with the grids (orange) just above them. On top of that are rows of cathode filaments (red). Wire connections (blue) pass current to the anodes and grids. The whole thing is vacuum...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
