2 Write a word equation and a symbol equation for the
reaction of solid zinc oxide
(ZnO) with sulfuric acid.

Zinc oxide is react with sulphuric acid to give zinc sulphate and water.

zinc oxide +sulphuric acid ⇒ zinc sulphate + water

Zno    +H2So4 ⇒ZnSo4 + H2O

SULPHURIC ACID = H2SO4

ZINC SULPHATE =ZnO

Explanation:

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
