Lessons 5.1-5.2 Reactivity of Metals Flashcards
What three materials are fed into the blast furnace?
HAEMATITE, limestone, and coke
These materials are essential for the production of iron in the blast furnace.
What is produced when hot air is blasted into the blast furnace?
Molten iron and molten slag
The hot air facilitates the chemical reactions necessary for iron production.
What is the general reaction equation for a metal reacting with an acid?
METAL + ACID → SALT + HYDROGEN
What determines how vigorously a metal reacts with an acid?
Its position in the reactivity series
What is the product when sodium reacts with water?
Sodium hydroxide + hydrogen
What happens when a metal reacts with water?
Hydrogen is always given off
The other product is either a metal hydroxide or a metal oxide.
What is formed when a metal reacts with oxygen?
Metal oxide
What is an example of a displacement reaction?
Magnesium + copper sulfate → Copper + magnesium sulfate
What is a displacement reaction?
A reaction where a more reactive metal displaces a less reactive metal from a compound.
What is the reaction between magnesium and copper sulfate?
Magnesium + copper sulfate → Copper + magnesium sulfate
What is produced in the thermite reaction?
Iron and aluminum oxide
What is the role of aluminum in the thermite reaction?
Aluminum displaces iron from iron(III) oxide due to its higher reactivity.
What does the reactivity of metals describe?
How easily an atom loses an electron
What is the order of the reactivity series from most to least reactive?
Potassium, Sodium, Calcium, Magnesium, Aluminium, Carbon, Zinc, Iron, Lead, Copper, Silver, Gold
What is a metal ore?
A mineral or mixture of minerals from which it is economically practical to extract some metal.
What type of reaction is used to extract metals from their oxides?
Reduction reaction
What happens when zinc reacts with copper sulfate?
Reaction happens
Zinc is more reactive than copper.
What is the chemical equation for the reaction between magnesium and copper oxide?
Mg(s) + CuO(s) → Cu(s) + MgO(s)
What is produced from lithium reacting with water?
Lithium hydroxide + hydrogen
What is the expected observation when magnesium reacts with copper sulfate?
Traces of a brown solid are left, and the solution turns colorless.
True or False: Copper can displace magnesium from magnesium sulfate.
False
Fill in the blank: A _______ reaction is one where a more reactive metal displaces a less reactive metal from a compound.
displacement
What is the product of magnesium reacting with hydrochloric acid?
Magnesium chloride + hydrogen
What is formed when lithium reacts with hydrochloric acid?
Lithium chloride + hydrogen
