Reactions of Metals

What is produced when a metal reacts with oxygen?

• metal + oxygen

• metal oxide

• water

• metal + hydrogen

When a metal reacts with dilute acid the two products are:

• salt + hydrogen

• oxygen + hydrogen

• salt + oxygen

• metal + hydrogen

What two reactants react together to form a metal hydroxide and hydrogen?

• metal + hydrogen

• metal + oxygen

• metal + acid

• metal + water

The reactivity series is:

• list of metals in order of similar properties

• list of metals with most reactive at the top and least reactive at the bottom

• list of metals with most reactive at the bottom and least reactive at the top

• list of metals in order of increasing atomic number

Order these metals from most reactive to least reactive; gold, magnesium, sodium, lead

• sodium, magnesium, lead, gold

• gold, lead, magnesium, sodium

• lead, sodium, gold, magnesium
