Polar or ionic substances dissociate into ions when dissolved in water.
<h3>What substances dissociate into ions when dissolved in water?</h3>
Ionic substances dissociate into ions when dissolved in water because water is also a polar by nature. We know that like dissolve like so polar substances dissolve in water and dissociate into ions i.e. positive an negative ions.
So we can conclude that polar or ionic substances dissociate into ions when dissolved in water.

Advantages of alloys:
-high strength-to-weight ratios
-a wide range of different alloys, to suit a range of different uses
-low density
Disadvantages of alloys:
-No fatigue limit
-prone to corrosion, so need protective finishes, particularly magnesium alloys
-Many alloys have limited strength, especially at elevated temperatures magnesium alloys have low strength
The mass of the mercury at 25°C is 121.806 g or 121.81 g.
<u>Explanation:</u>
The volume of the mercury = 9.000 mL.
The density of the mercury at 25°C = 13.534
.
The mass of the mercury =?.
density d = 
.
⇒mass= density×volume.
mass=13.534×9.000.
mass=121.806 g or 121.81 g.
Answer:
Hurricanes and tropical storms gain their power from heated water evaporating from the ocean.
Explanation:
<h3>Brown Water Effect </h3>
- The brown ocean effect is an observed weather phenomenon involving some tropical cyclones after landfall. Normally, hurricanes and tropical storms lose strength when they make landfall, but when the brown ocean effect is in play, tropical cyclones maintain strength or even intensify over land surfaces.
