  1. A spectator ion is an ion that exists in the same form on both the reactant side and the product side of a chemical reaction. NH4+ +NO3- +H++OH-=H3O++NH3+NO3-
  2. Can we have a change without a speed of change ?I suppose not In my mind: Time=Change/Speed of change
  3. In first case will be a neutralization reaction between a weak acid and a strong base 5 mol HCOOH+5mol KOH=5 mol HCOOK+5 mol HOH Products are a salt (a conjugate base of a weack acid )and water 6 mol HCOOH+5 mol KOH=1 mol HCOOH+5 mol HCOOK+5 mol HOH is a buffer solution
  4. I thought of the elementary particles as the pieces of the LEGO game (https://en.wikipedia.org/wiki/Lego) I associate a label with each seemingly identical piece Can we sent a fossil for 1 to 10000 years in the past?
  5. Imagine that we attach a label to each elementary particle in the Universe, each label having a unique natural number ... In this model, everything who can be send in past is represented a series of labels. If a thing is sent back in time...a phone for exemple (we assume that it contains the elementary particles with the numbers 7 and 1003) then we will find in the past, simultaneously these elementary particles twice, in the same Universe and at the same time. Do you think it is possible?
