Frage 5
Frage
Complete the symbol equation:
Calcium oxide (aq) + water (l) ==> calcium hydroxide (aq)
[blank_start]CaO[blank_end] + [blank_start]H₂O[blank_end] ==> Ca([blank_start]OH[blank_end])₂
Frage 6
Frage

Frage 7
Frage
A solution of calcium [blank_start]hydroxide[blank_end] in water ([blank_start]limewater[blank_end]) reacts with [blank_start]carbon[blank_end] [blank_start]dioxide[blank_end] to produce calcium [blank_start]carbonate[blank_end]. [blank_start]Limewater[blank_end] is used as a test for [blank_start]carbon[blank_end] [blank_start]dioxide[blank_end]. [blank_start]Carbon[blank_end] [blank_start]dioxide[blank_end] turns [blank_start]limewater[blank_end] cloudy.
