6 mark halogen displacement question

Write this into your book as a model answer.
Order of reactivity: _____________ > ____________ > ___________
Experiment
add (aqueous) chlorine to a solution of potassium bromide
 the solution turns ___________ as bromine is produced
Conclusion/Explanation and equation:
(so) chlorine ______________ bromine

Full equation
Cl₂ + 2KBr → Br₂ + 2KCl
__________ equation
/ Cl₂ + 2Br⁻ → Br₂ + 2Cl⁻
Experiment
add (aqueous) bromine to a solution of potassium
iodide
 the solution turns __________ as iodine is produced
Conclusion/Explanation and equation:
(so) bromine is _________ reactive than
Br₂ + 2KI → I₂ + 2KBr
or ionic equation
Br₂ + 2I⁻ → I₂ + 2Br⁻
Experiment
add (aqueous) chlorine to a solution of potassium iodide
 the solution turns brown
 iodine is produced
Conclusion
(so) chlorine is more reactive than iodine
Cl₂ + 2KI → I₂ + 2KCl

Cl₂ + 2I⁻ → I₂ + 2Cl⁻
At room temperature Br₂
is a gas
is a liquid
is a solid
At room temperature I₂
is a gas
is a liquid
is a solid
Chlorine gas is

What did Mendeleev leave in his periodic table?
Gaps for undiscovered elements
I honestly can not think of another answer here
In the modern periodic table the elements are in order of increasing
atomic mass
atomic number
The number electrons in the outer shell of an element is equal to the
period
group
Match the number to the description for the halogens is water or petroleum ether (organic layer) Focus simulation halogens

Which letter shows iodine in cyclohexane?

A
B
C
D

F
Use the results of the displacement reactions to place the halogens in order of reactivity from most reactive to least reactive. Note 1. the halide ions would have to be added as a salt such as KCl, KBr and KI rather than the individual ions Note 2. The potassium halide solutions are all colourless. Note 3. The final colour of the sample depends upon the halogen present only.

Most reactive
Least reactive
Chlorine
Bromine
Iodine
