Properties of Water Test

1

In a water molecule, the oxygen atom is

positively charged

Negatively charged

both positively and negatively charged

neutral (no charge)

1

Water molecules and other water molecules stick together through what type of bonding

covalent bonds

hydrogen bonds

chemical bonds

all of these are true

1

Cohesion occurs when water molecules

are attracted to each other

are held together with hydrogen bonds

stick to other water molecules

all of these are true

1

Adhesion occurs when water molecules

stick to other water molecules

are pulled apart

stick to other substances

none of these are true

1

Water has a high latent heat; this means

it doesn't take a lot of heat to heat water

the bottom of the ocean is colder

it takes a LOT of heat to heat up water

oceans don't freeze solids

1

Which of the following scenarios is an example of cohesion

water molecules stick to the surface of a mirror

water molecules stick to one another and form a bead

water sticks to the walls of blood vessels

1

Certain insects can "walk on water" due to the _ of water, created by .

adhesion; specific heat

surface tension; cohesion

this is a false statement

cohesion; universal solvent

1

How many hydrogen atoms does each water molecule have?

3

1

6

2

1

What property allows water to stick to glass ?

Cohesion

Adhesion

Surface tension

Solubility

1

Which of the following is more electronegative in a water molecule?

Hydrogen

Oxygen

1

What is the definition of polar?

when a molecule can be dissolved in water

when a molecule cannot be dissolved in water

when covalent molecule doesn't share electrons evenly

when a covalent molecule does share electrons evenly

1

Atoms bonded together often form a(n)....

element

osmosis

molecule

density

1

The atoms in a water molecule are covalently bonded? This means electrons are _____

removed

transferred

destroyed

shared

1

Water is a compound formed when two hydrogen atoms and one oxygen atom ______ bond.

covalently

ionically

1

What type of covalent bonds do water molecules have?

nonpolar covalent

polar slightly ionic

polar covalent

charged covalent

1

Water will dissolve salt because

they are ionic bonds

water is nonpolar covalent bond and salt is a polar covalent bond

water is an ionic bond and salt is a polar bond

water is a polar covalent bond and salt is an ionic bond

1

Water does not dissolve oil because

water has an ionic bond

oil is a polar molecule and water is nonpolar molecule

water is a polar molecule and oil is a nonpolar molecule

oil is ionic

1

Which type of bonds do polar covalent bonds break down in chemical reactions?

polar covalent and ionic bonds

nonpolar covalent bonds and polar covalent bonds

ionic bonds and nonpolar bonds

none of the above

1

Water molecules in ice are farther apart than in liquid water: so ice is less dense and floats.

True

False

1

Water is a universal solvant because?

it is a polar covalent bond that can break down both ionic molecules and polar covalent molecules.

Water is ionic and breaks down polar molcules

Water is a non polar covalent bond that breaks down only other non polar molecules

water is what everything is made of so it must be the universal solvent.
