I remember coming across this question and the options were:
KOH, HCN, NH₃, HI, Sr(OH)₂
Now, a substance with a low pH is one that dissociates completely in water to release hydrogen ions, while basic substances dissociate completely to release hydroxide ions. Therefore, in the order of increasing pH:
HI, HCN, NH₃, Sr(OH)₂, KOH
Answer:
Collection - Evaporation - Condensation - Precipitation
Explanation:
The Water cycle is a series of continuous events that cause rain
C because it’s talking about the earth and it’s rotating
<u>Answer:</u>

∆x is the Uncertainty in the position of the particle
∆p is the Uncertainty in the momentum of the particle



is the answer
Answer:
Add copper (II) oxide (insoluble base), a little at a time to the warm dilute sulfuric acid and stir until the copper (II) oxide is in excess (stops disappearing) Filter the mixture into an evaporating basin to remove the excess copper (II) oxide. Leave the filtrate in a warm place to dry and crystallize.
