Water Flashcards
What do polar and non-polar mean?
In simple terms, polar means oppositely charged, and non-polar means equally charged. Covalent bonds can be polar or non-polar. To understand the difference between polar and non-polar bonds, it is essential to comprehend electronegativity.
Water is a universal solvent because it …
dissolves most substances.
What happens when water turns into ice?
he water makes a crystal structure.
All of the above.
The water becomes a solid.
The water expands when it freezes.
All of the above.
Why is water considered polar?
It has a partial charge
Which is true about a water molecule?
The oxygen has a partially negative charge
Water has a high specific heat compared to other liquids.
It requires more energy to change temperature
Water is attracted to the sides of a glass tube due to which of its properties?
Adhesion “adhere, to stick”
Attractions between the negative Oxygen atom of one water molecule and the positive Hydrogen atom of another water molecule are called
Hydrogen bonds
Large bodies of water, such as lakes and oceans, do not quickly change in temperature. Why?
Water has a high heat capacity.
The substance being dissolved in a solution.
solute
The substance in which a solute is dissolved
solvent
If you are making Kool-aid with sugar, Kool-aid powder, and water….which part is the solvent? (does the dissolving)
water
The term that describes the idea the hydrogen atoms of a water molecule has the positive charges and oxygen atom has a negative charge. These charges are opposite which is why the water molecule is able to stay bonded.
Polarity
Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature. What is the reason for this phenomenon?
Water has a high heat capacity
Why does ice stay at the top of oceans instead of sinking to the bottom?
Ice is less dense than liquid water.
