Do binary oblique elastic collisions lead to velocity triangles in all cases, just as they lead to momenta triangles? Or, are there exceptions where the velocities do not form a triangle while the momenta do?
Thanks.
'If you use any other electrode, H+ gets reduced and hydrogen is produced, there is intermediate metallic sodium produced'. This is what I have been saying, too!

The following references may be consulted for electrolytic deposition of sodium from aqueous solutions of NaCl. It is a well known industrial process. Therefore, you may not find it difficult to get references for this process. I give below two, I gathered from the net.
1. See (b) The mercury...
'Even if you try to force lower reduction potential, it is still water that reacts first. Only once there is no water in the solution, we can start to observe Na+reduction'.
When we force the electrode potential to values lower than that corresponding to the equilibrium potential of sodium...
Dear Borek
What you wrote is not clear to me - 'water reacts directly producing hydrogen'. Water reacts with what?
'We observe exactly the same reaction in solutions that contain other cations'. What reaction are you referring to?
If we electrolyse water containing small quantities of any...
When we electrolyze aqueous NaCl solution using electrodes, such as graphite, Chlorine gas is evolved at the anode and Sodium metal is formed at the cathode - but Sodium being highly reactive metal - reacts with water producing Hydrogen gas and Sodium Hydroxide. Therefore, you don't find any...
When you take two couples at random (both can be from the same side of zero (not of the table!)) one will be upper and the other lower.
You can go about doing what you want, with that understanding.

In the table you have chosen, the upper couple that you choose acts as anode (the negative terminal) and the lower couple the cathode (the positive terminal) of the battery.
P. Radhakrishnamurty
I missed mentioning in my above reply that the negative terminal of the battery is the anode of the battery, as for example, the Zn can in the torch cell (primary) battery, at which oxidation of Zn occurs. This terminal is connected to the electrode, called as the cathode, of the electrolysis...
Whether, it is a battery (source of electrical energy) or an electrolysis cell (sink of electrical energy), oxidation occurs at the anode and reduction occurs at the cathode in an electrochemical cell. To understand the motion of positive and negative charges through the circuit, it is better to...
This is a classical problem in electrochemisty. You can find other tables of standard potentials, E°s, of half cell reactions having the same numerical value but opposite sign, for the reactions in your table . For example for the Li/Li+ -3.040V. Thus, every reaction in your table and that...
'And if we set
GM/R=g'
You can see this setting is incorrect; the units do not balance. Consequently, your result for W also doesn't give the right equation.
In the limits of integration, if you put (R+a) and (R+h) in place of a and h, you get:
W= mgR2 [(R+a)-1 - (R+h)-1]
Neglecting R(a+h) and...
When we place a particle with zero velocity at a point on a line of field, the particle moves along the field line. When we put a particle with a non zero velocity, it crosses from one field line to another as it moves. In the process of crossing the field lines it changes (gains or losses) its...
This Para: Its vertical velocity will be zero after hitting the ground, but the process of hitting the ground involves a large upward acceleration. Applying a SUVAT equation across the period from before to after impact is therefore not valid. The ‘final’ velocity here means at the instant...
