Chemistry - Metals and Non-Metals

What do metals combine with to form metal oxides?

Metals combine with oxygen to form metal oxides.

Give an example of a metal combining with oxygen.

For example, copper plus oxide gives rise to copper oxide.

How do sodium and potassium react with oxygen?

Sodium and potassium react so vigorously with oxygen that they catch fire if kept in open so they are kept immersed in kerosene.

What covers surfaces of magnesium, aluminum, zinc and lead?

Surfaces of magnesium, aluminum, zinc and lead are covered with a thin layer of oxide which prevents them from further oxidation.

How does iron behave on heating?

Iron does not burn on heating but iron fillings burn vigorously.

How does copper react with oxygen?

Copper does not burn but is coated with black copper oxide.

How do silver and gold react with oxygen?

Silver and gold do not react with oxygen.

How do metals react with water?

Metals react with water to produce metal hydroxide and hydrogen gas.

What happens when metal oxide reacts with water?

This metal oxide further reacts with water to give metal hydroxide.

What does metal plus water give rise to?

Metal plus water gives rise to metal oxide plus hydrogen.

How do sodium and potassium react with cold water?

Sodium and potassium react vigorously with cold water.

How does magnesium metal react with hot water?

Magnesium metal reacts with hot water to produce magnesium hydroxide and hydrogen gas.

How do aluminum and zinc react with steam?

Aluminum and zinc react with steam to produce metal oxide and hydrogen gas.

How do silver, gold, copper and lead react with water?

Metals like silver, gold, copper and lead do not react with water.

What is the mnemonic for the activity series of metals?

A mnemonic for the activity series of metals will be playful snakes can make angry zebras into tiny lazy happy cats singing gleefully.
