Answer:

Explanation:

word equation:

a) Bromine + potassium iodide → potassium bromide + iodine

Chemical equation:

Br₂ + KI → KBr + I₂

Balanced chemical equation:

Br₂ + 2KI → 2KBr + I₂

B) word equation:

Iodine + potassium astatide → potassium iodide + astatine

Chemical equation:

I₂ + KAt → KI + At₂

Balanced chemical equation:

I₂ + 2KAt → 2KI + At₂

c) word equation:

chlorine + sodium iodide    →  sodium chloride + iodine

Chemical equation:

 Cl₂ + NaI → NaCl + I₂

Balanced chemical equation:

Cl₂ + 2NaI → 2NaCl + I₂

d) word equation:

fluorine + sodium bromide → sodium fluoride + bromine

Chemical equation:

 F₂ + NaBr → NaF + Br₂

Balanced chemical equation:

F₂ + 2NaBr → NaF + Br₂

e) word equation:

fluorine + potassium chloride → potassium fluoride + chlorine

Chemical equation:

 F₂ + KCl → KF + Cl₂

Balanced chemical equation:

  F₂ + 2KCl → KF + Cl₂
