The movement of gas through a tiny hole is called Effusion. Effusion occurs when there is a barrier with one or many small holes that prevent the gas to expand into the new volume unless a gas molecule happens to travel through the hole. The difference between Effusion and Diffusion is the barrier between the two volumes.
Answer:
Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
Explanation:
The net reaction is Z n ( s ) + 2 H + ( a q ) → Z n 2 + ( a q ) + H 2 ( g ) The C l − ions are spectators - they don't change.
A) LITHIUM is the least reactive alkali metal
B) FRANCIUM is the most reactive alkali metal
C) BERYLLIUM is the least reactive alkaline earth metal
D) RADIUM is the most reactive alkaline earth metal
E) TENNESSINE is the most reactive halogen
For E it might also be Astatine because Tennessine is a fairly new
