Hydrogen atoms on collision (based on energy conservation)

AI Thread Summary
The discussion centers on the impossibility of the reaction H + H → H2 + 5 eV occurring in free space due to violations of conservation laws. It highlights that during a simple two-body collision, the conservation of momentum and energy cannot be satisfied if energy is released. Participants seek clarification on how to prove this impossibility, emphasizing that the reaction cannot occur as stated. The consensus is that the reaction contradicts fundamental physical principles. Overall, the conversation underscores the challenges of energy conservation in chemical reactions involving hydrogen atoms.

"Given a simple and violent chemical reaction { H + H → H2 + 5eV }. however when hydrogen atoms collide in free space they simply bounce apart. the reason is that it is impossible to satisfy the laws of conservation of momentum and conservation of energy in a simple 2 body collision which releases energy..."

how can i prove this statement?

What exactly are you supposed to prove? That H + H = H2 + 5 eV is impossible?
 
we have to prove that it is impossible ... the statement stands for itself,,, the reaction is impossible because of some facts like it don't satisfy the laws of conservation of energy. please help.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
