Single/Double Displacement Flashcards
1
Q
metal displaces metal
A
swap metals, ONLY IF THE SINGLE ONE IS MORE REACTIVE
2
Q
metal displaces H ion from acid
A
use activity series, then swap as is remember diatomics!!
3
Q
metal displaces H from water
A
use activity series, H-OH
- format: H2 + MOH
4
Q
Nm displaces Nm
A
compare 2 Nm, use halogen activity series
5
Q
DD to prod a precipitate
A
yeah
6
Q
DD to prod H2O
A
acid+base (both have to be aq) -> salt+water
7
Q
DD to prod CO2
A
metal carbonate + acid -> salt + H2O + CO2
8
Q
DD to prod SO2
A
metal sulfITE + acid -> salt + H2O + SO2
9
Q
DD to prod NH3
A
ammonium salt + BASE -> salt + H2O + NH3
10
Q
DD to prod H2
A
metalH+H2O -> metal(OH) + H2
11
Q
DD to prod H2S
A
metal sulfIDE + acid -> salt + H2S
12
Q
how crystal structure affects solubility
A
stronger ionic bonds = less soluble
weaker “ = more soluble
+ explain with NaCl
