Reactions of Metals and Metal Compounds

Flashcards covering tests for gases, general reaction equations, and specific examples of metal, carbonate, oxide, and neutralisation reactions.

What gas is produced when a metal reacts with an acid?

Hydrogen gas

How do you test for hydrogen gas in the lab?

Apply a lit splint; a squeaky "pop" confirms hydrogen

State the general word equation for a metal reacting with an acid.

Metal + Acid → Salt + Hydrogen

Give the products of calcium reacting with hydrochloric acid.

Calcium chloride + Hydrogen

Give the products of zinc reacting with hydrochloric acid.

Zinc chloride + Hydrogen

Give the products of lithium reacting with sulphuric acid.

Lithium sulfate + Hydrogen

What observation confirms the presence of carbon dioxide when bubbled through limewater?

Limewater turns milky/cloudy

State the general word equation for a metal carbonate reacting with an acid.

Metal carbonate + Acid → Salt + Carbon dioxide + Water

Give the products of magnesium carbonate reacting with hydrochloric acid.

Magnesium chloride + Carbon dioxide + Water

Give the products of sodium carbonate reacting with sulphuric acid.

Sodium sulfate + Carbon dioxide + Water

What alternative name is often used for metal oxides?

Bases

State the general word equation for a metal oxide reacting with an acid.

Metal oxide + Acid → Salt + Water

Give the products of magnesium oxide reacting with hydrochloric acid.

Magnesium chloride + Water

Define a neutralisation reaction.

A reaction in which an acid reacts with an alkali to form salt and water

State the general word equation for neutralisation.

Acid + Alkali → Salt + Water

What is an alkali?

A metal oxide or metal hydroxide that has been dissolved in water

Give the products of sodium hydroxide reacting with hydrochloric acid.

Sodium chloride + Water

Which gas is released when a metal carbonate reacts with an acid?

Carbon dioxide
