chapter 12 - reactivity series Flashcards
(12 cards)
What is the purpose of the reactivity series?
To arrange metals from the most reactive to the least reactive.
Which metals are included in the reactivity series?
Calcium, copper, hydrogen, iron, lead, magnesium, potassium, silver, sodium, zinc.
What is the reaction of metals with cold water?
Metal + water → metal hydroxide + hydrogen.
Which metals react violently with cold water?
More reactive metals such as potassium and sodium.
What is the reaction of metals with steam?
Metal + steam → metal oxide + hydrogen.
What type of metals react with steam instead of cold water?
Some metals such as zinc and iron.
What is the reaction of metals with dilute hydrochloric acid?
Metal + dilute hydrochloric acid → metal chloride + hydrogen.
Which metals react with dilute hydrochloric acid?
Metals above hydrogen in the reactivity series.
Fill in the blank: The order of reactivity of metals can be determined by their reactions with _______.
cold water, steam, and dilute hydrochloric acid
True or False: All metals react with cold water.
False
What happens to more reactive metals in reactions with water and steam?
They react more violently.
Why are certain metals used to make food cans?
Due to their reactivity properties.
