both positively and negatively charged
positively charged
Negatively charged
Water molecules stick together through what type of bonding
chemical bonds
all of these are true
covalent bonds
hydrogen bonds
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
Adhesion occurs when water molecules
stick to other substances
none of these are true
are pulled apart
stick to other water molecules
Water has a high latent heat; this means
oceans don't freeze solids
it takes a LOT of heat to heat up water
the bottom of the ocean is colder
it doesn't take a lot of heat to heat water
Which of the following scenarios is an example of cohesion
water molecules stick to one another and form a bead
water sticks to the walls of blood vessels

What property allows water to stick to glass ?
Adhesion
Cohesion
Surface tension
Solubility
Which of the following is more electronegative (has more of the negative charge) in a water molecule?
Hydrogen
Neither, they are both equal
Oxygen
What is the definition of polar?
when a molecule can be dissolved in water
when a covalent molecule does share electrons evenly
when a molecule cannot be dissolved in water
when covalent molecule doesn't share electrons evenly
The atoms in a water molecule are covalently bonded? This means electrons are _____
transferred
shared
destroyed
removed
Water is a compound formed when two hydrogen atoms and one oxygen atom ______ bond.
hydrogen
ionically
covalently
What type of covalent bonds do water molecules have?
charged covalent
nonpolar covalent
polar covalent
polar slightly ionic
Water will dissolve salt because
water is a polar covalent bond and salt is an ionic bond
water is nonpolar covalent bond and salt is a polar covalent bond
they are ionic bonds
water is an ionic bond and salt is a polar bond
Water does not dissolve oil because
oil is ionic
oil is a polar molecule and water is nonpolar molecule
water has an ionic bond
water is a polar molecule and oil is a nonpolar molecule

none of the above
nonpolar covalent bonds and polar covalent bonds
ionic bonds and nonpolar bonds
polar covalent and ionic bonds
