Answer 59

Reacts instantly, produces iron (lll) fluoride

Question 60

Chlorine reaction with iron wool

Answer 60

Reacts with heated iron wool very quickly, produces iron (lll) chloride

Question 61

Bromine reaction with iron wool

Answer 61

Both the bromine and iron wool must be heated, slower than chlorine, produces iron (lll) bromide

Question 62

Iodine reaction with iron wool

Answer 62

Both the iodine and wool must be heated strongly, slow reaction, produces iron (lll) Iodide

Question 63

Displacement in group 7

Answer 63

The more reactive element swaps places with the less reactive element

Question 64

Why does group 7 reactivity decrease down the group ?

Answer 64

There and more shells between the nucleus and outer electron, the attraction between the nucleus and outer electron decreases, it becomes harder to gain the outer electron
