Unit 7 (H) Lesson 1 Review

Calcium carbonate decomposes into calcium oxide and carbon dioxide.

Calcium oxides react to form calcium carbonate.

Calcium and oxygen mix to produce calcium carbonate.

Calcium forms carbonate when heated.

Fluorine reacts with itself to produce hydrogen.

Hydrogen decomposes into hydrogen fluoride.

Hydrogen combines with fluorine to form hydrofluoric acid

Hydrogen atoms form a bond with oxygen.

Barium sulfide + copper (I) acetate → Barium copper (I) + acetate sulfide

Barium sulfide + copper (II) acetate → Barium copper (II) + acetate sulfide

Barium acetate + copper (II) sulfide → Barium sulfide + copper (II) acetate

Barium sulfide + copper (I) acetate → Barium acetate + copper (I) sulfide
