Chemical Equations with State Symbols Quiz

Chemical Reactions

• The reaction of calcium oxide with water to form slaked lime is an example of a neutralization reaction.

Precipitation Reactions

• The reaction of barium chloride and sodium sulphate to form barium sulphate and sodium chloride is an example of a precipitation reaction.
• The equation 'Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s)' represents a precipitation reaction.

Neutralization Reactions

• The reaction of sodium hydroxide solution with hydrochloric acid solution to produce sodium chloride and water is an example of a neutralization reaction.

Decomposition Reactions

• The equation 'Zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g)' represents a decomposition reaction.
• Decomposition reactions are considered the opposite of combination reactions because in decomposition reactions, a single compound breaks down into two or more simpler substances, whereas in combination reactions, two or more substances combine to form a single compound.

Displacement Reactions

• The reaction in the refining of silver, where copper metal displaces silver from silver nitrate solution, is an example of a displacement reaction.
