4.4 Single Displacement Reactions Flashcards
In a single displacement reaction, one element takes ______________ in a compound.
the place of another
The Activity Series List allows for the prediction of
whether a ________________ will occur.
single displacement reaction
A more reactive metal in its elemental form will displace a ____________ in an ionic compounds.
less reactive metal
how are the metals arranged on the activity series list?
The elements are arranged from MOST reactive at the top of the list to least reactive at the bottom of the list
Case 1: Metal displacing a _____ in an ionic compound
metal
AB + C 🡪 CB + A
Case 2: Non-Metal displacing a __________ in an ionic compound
non-metal
AB + C 🡪 AC + B
case 2 typically occurs when a _________ molecule reacts with a _________-containing ionic
compound.
diatomic; halogen
A metal displacing Hydrogen from _________
Acid or Water
Displacement from an Acid:
The metal displaces the hydrogen ions from the ionic compound and bonds to the anion to form a new compound.
Identify which is higher on the activity series: LITHIUM or HYDROGEN.
If lithium is higher, then the reaction ______. If hydrogen is higher, ________ occurs.
proceeds; no reaction
Case 4: Displacement from Water
The metal displaces the __________ ion from water, and the metal forms a new _____________ with the remaining hydroxide ion.
hydrogen; ionic compound
