Which statement concerning a possible mechanism for a reaction is false? a possible mechanism must be consistent with the experimental data. the slow step will only include reactants listed in the overall chemical equation. the speed of the slow step limits the rate at which the overall reaction occurs. the elementary steps must add up to the equation for the overall reaction. each elementary step is represented by a balanced equation.

It must be measured in k.hope my answer is to you : )

Precipitate, and gas

First up write the aim
then write the materials reqd.
then the procedure which you follow
then observation
then conclusion
then you can write lab safety rules or precautions(you can avoid if u want).
lemme' give an example
aim: to observe the double displacement reaction
materials reqd: bacl2 and na2so4, test tubes and a dropper
procedure:
1. take bacl2 in a test tube and na2so4 in the other.
2. then pour bacl2 into na2so4 solution.
3. observe
observation:
you will see that a white precipitate is formed called baso4. along with that common salt or nacl is formed.
the equation is
bacl2+na2so4=baso4+2nacl
conclusion:
a double displacement reaction is observed.
hope it
