word equation:

balanced equation:

 

b)   Potassium metal combines with oxygen gas to produce solid potassium oxide.

word equation:

balanced equation:

 

c)    Lithium sulphate combines with barium chloride and produces solid barium sulphate and aqueous lithium chloride. Both of the reactants are dissolved or are soluble in water (aqueous).

word equation:

balanced equation:

 

Answer 1

a)Aluminium +Flourine =Aluminium Flouride

Al (s) + F2(g) → AlF3

b) Potassium +Oxygen =Potassium Oxide

K2O2 + 2 K → 2 K2O.

c) Lithium sulfate + barium chloride =barium sulfate + lithium chloride.

Li₂SO₄ + BaCl₂ → BaSO₄ + 2LiCl
