Properties of water
Name the property: Water sticking to itself
What is cohesion?
This determines the amount of bonds an atom can make.
What are unpaired electrons?
What does the chemical symbol H20 represent?
What is water?
What is an ion?
What is an element with a charge?
How many bonds can oxygen form?
2
Name the property: Humans must stay within a certain temperature range, and are made primarily of water.
What is high specific heat?
Which is the strongest type of bond between covalent, hydrogen, and ionic?
Ionic
What do you can an element that has different versions, each with a different number of neutrons?
Isotope
What do we call the substance that gets dissolved in a solution?
How do nonpolar and polar molecules interact?
They repel each other.
Name the property: Humans cool themselves down by sweating.
What is high heat of vaporization?
The sharing of electrons between atoms in a molecule.
What is covalent bonding.
Metal or Nonmetal: Chlorine
What is a nonmetal.
What do we call the substance that does the dissolving in a solution?
What is a solvent?
What symbol represents a partial or relative charge?
Lower case delta
Which feature of water allows it to be the universal solvent?
What is polarity.
A weak bond formed between hydrogen and oxygen in different water molecules.
What is hydrogen bonding.
What does it mean when an element has a superscript with a positive?
All acceptable: The element has lost electrons, is positive, or is a cation.
Why do water molecules stick together?
What is hydrogen bonding (weak attractions between the relatively positive hydrogen and relatively negative oxygen).
Which 2 properties of water allow water to travel up to the leaves of plants from soil?
BOTH adhesion and cohesion
Which feature of water is responsible for water being more dense as a liquid than a solid?
Hydrogen Bonds
This type of bond exists because electrons are donated & accepted (transferred) between molecules.
What is ionic bonding.
What kind of bond would exist between KBr?
What is ionic.
What does it mean to be nonpolar?
The electrons in the molecule are equally shared.
What is the chemical symbol for methane?
CH4
