Displaceme Date: nt Keyword s Reactions Learning objectives: To know – what a displacement reaction is To understand – how to use the reactivity series to predict displacement reactions DO NOW! To be able to – Write balanced Copy, date, symbol equations for title and displacement reactions L.O into your book. Literacy focus: Using scientific key  Displacement Displacement: Replacing a less reactive metal with a more reactive one in a compound. (you can think of displacement as replacement) Key Word Literacy focus: Using scientific key To know – what a displacement reaction is  words When a metal reacts with an acid, the following word equation is given: metal + acid  a salt + hydrogen Literacy focus: Using scientific key  Reactivity Series potassiu increasing reactivity sodiu m PLEASE calcium m SEND magnesiu CHARLI aluminium m E’S Carbon MONKE zinc YS iron AND lea ZEBRAS copper d IN silver LEAD gold CAGES platinu SECURE m LY Make a mnemonic to GUARD remember the  Sulphuric acid Hydrochloric H2SO4 Nitric acid acid HCl HNO3 What do these three compounds have in common?  Reactivity Series potassiu sodiu m increasing reactivity Any metal PLEASE calcium m above SEND magnesiu hydrogen will CHARLI react with acid aluminium m E’S Carbon MONKE zinc YS iron AND lea ZEBRAS d Hydrog IN copper en Any metal LEAD silver below CAGES gold hydrogen will SECURE platinu not react with acid LY m GUARD We’re going to use some of these characters in our model. Rule: Most reactive character wins… Literacy focus: Using scientific key  Who would win the Chloride Belt?
