Which end of the water molecule has a slightly NEGATIVE charge?
the oxygen end
the hydrogen end
both ends are slightly positive
Attractions between the partially negative oxygen atom of one water molecule and the partially positive hydrogen atom of another water molecule are called
Covalent bonds
Ionic bonds
Hydrogen bonds
What word describes when water sticks to OTHER surfaces?
cohesion
adhesion
surface tension
What two elements make up water?
oxygen and carbon
hydrogen and oxygen
hydrogen and carbon
Which end of the water molecule has a slightly POSITIVE charge?
the oxygen end
the hydrogen end
both ends are slightly positive
When water molecules stick easily to other water molecules, this is called what?
cohesion
adhesion
surface tension
COHESION is best defined as:
Water's ability to stick to itself
Water's ability to stick to other surfaces
The property of a liquid that allows it to resist an external force on its surface
Wet sand sticks together better than dry sand because:
There is INCREASED surface tension
There is DECREASED surface tension
There is NO surface tension
When drinking water out of a glass, some of the water droplets stay behind in the glass. This is because:
The water uses adhesion to stick to the glass
The water uses cohesion to stick with other water molecules
The water uses cohesion to stick to the glass
Water is a POLAR molecule. In this molecule:
Oxygen pulls electrons towards themselves, causing UNEQUAL sharing
Hydrogen pulls electrons towards themselves, causing UNEQUAL sharing
Hydrogen and oxygen share the electrons EQUALLY
Coulomb's Law states that OPPOSITE charges:
attract
repel
dissolve
Coulomb's Law states that LIKE charges:
attract
repel
dissolve
In hydrogen bonding what two atoms are attracted to each other on NEIGHBORING water molecules?
oxygen to oxygen
hydrogen to oxygen
hydrogen to hydrogen
Water strider bugs can walk on water because:
hydrogen bonding causes an INCREASE in surface tension
hydrogen bonding causes a DECREASE in surface tension
hydrogen bonding causes in INCREASE in adhesion
A water molecule is made up of:
2 hydrogen atoms & 1 oxygen atom
1 hydrogen atom & 2 oxygen atoms
1 hydrogen atom & 1 oxygen atom
2 hydrogen atoms & 2 oxygen atoms
When there is a POLAR bond that means:
Electrons are shared UNEQUALLY between atoms
Electrons are shared EQUALLY between atoms
Electrons are transferred from one atom to another
What is the correct chemical formula for water?
H2O
HO2
H2O2
2H1O
Which of the following is an example of COHESION?
water sticking to water
water sticking to glass
oil sticking to plastic
hydrogen sticking to oxygen
Water is polar. What does that mean?
it is a molecule with opposite charges on opposite ends
it is a molecule with no charge
it is a molecule with identical charges on opposite ends
it is a molecule with too many protons
