Definitions
Substances that undergo a chemical change
What are Reactants?
A bond that forms between atoms of nonmetals when they share valence electrons.
What is a covalent bond?
The reason water has so many interesting properties.
What is water's polarity?
What is 3?
A molecule that has slight positive and negative charges due to an imbalance in the way electrons are shared.
What is a Polar molecule?
New substances formed as a result of a chemical change.
What are Products?
A bond that forms between molecules as a result of the attraction of slight charges on atoms due to uneven sharing of electrons within the molecule, such as between molecules of water.
What is a hydrogen bond?
Hydrogen bonding keeps the water molecules closer together and limits their movement.
What is the reason water is a liquid and not a gas at room temperature?
AgNO3
What is 5?
The force of attraction between molecules of the same substance so that they tend to stay together.
What is cohesion?
A force of attraction between atoms or a group of atoms due to the sharing or transferring of electrons.
What is a Chemical bond?
A chemical bond that forms between oppositely charged atoms or groups of atoms.
What is an ionic bond?
Water molecules are closer together when water is a liquid compared to when water is a solid.
What is the reason ice floats?
2CO
What is 4?
The force of attraction between molecules of different substances so that they tend to stick together.
What is adhesion?
An atom or group of atoms that has a positive or negative charge.
What is an Ion?
The weakest type of chemical bond.
What is the hydrogen bond?
Hydrogen bonds in water molecules require much heat to increase the temperature of water.
What is the reason water has higher melting and boiling points than other similar compounds?
C8H10N4O2
What is 24?
When an atom has a complete set of valence electrons.
What is a stable electron configuration?
