REACTIVITY AND SALTS

How can you tell that a metal is reacting with water?

• Colour change
• Bright light
• Fizzing
• It gets colder

What gas is always produced when a metal reacts with water?

• Oxygen
• Carbon Dioxide
• Hydrogen
• Carbon Monoxide

As well as a gas, there is another product made when an acid reacts with a metal. What is the name for this?

• Salt
• Water
• Alkali
• Carbon

When sodium reacts with hydrochloric acid, what is the name of the salt formed?

• Sodium Hydride
• Sodium Chloride
• Sodium Hydrochloric
• Sodium Chlorine

When potassium reacts with sulphuric acid, what is the name of the salt produced?

• Potassium Sulphide
• Potassium Sulphur
• Potassium Sulphuric
• Potassium Sulphate

When a metal salt reacts with a more reactive salt, what sort of reaction occurs?

• Displacement
• Neutralisation
• Combustion
• No Reaction

When copper and magnesium sulphate are mixed together, there is no reaction. Why?

• Magnesium is more reactive than copper
• Copper is more reactive than magnesium
• Copper never reacts with metal salts
• Magnesium Sulphate never reacts with metals

In order to make use of the many useful properties of metals, we need to extract them so that they are in their pure form. A common way of extracting many of the less reactive metals is to heat their minerals with what?

• Carbon
• Helium
• Oxygen
• Silicon

What is the word equation for the reaction between sodium and water?

• sodium + water → sodium hydroxide + hydrogen

• sodium + water → sodium hydroxide + oxygen

• sodium + water → sodium oxide + hydrogen

• sodium + water → sodium oxide + oxygen

What is the salt that is produced in the reaction of zinc with sulfuric acid?

• zinc chloride

• zinc hydroxide

• zinc nitrate

• zinc sulfate
