Types of chemical bonds - correct answer -ionic, covalent,
metallic
Ionic bonds - correct answer -Formed when one or more
electrons are transferred from one atom to another
Covalent bonds - correct answer -Bonds created by sharing
electrons with other atoms.
Metallic bonds - correct answer -a bond formed by the attraction
between positively charged metal ions and the electrons around
them
States of matter - correct answer -solid, liquid, gas
, Page | 2
Why is water special? - correct answer --good solvent
-high heat capacity/thermal inertia
-unusual density properties
Why is carbon special? - correct answer -Carbons can bond to
one another and form thousands/millions of molecules.
What is plastic - correct answer -A man-made chemical
What is used to make plastic - correct answer -crude oil
Types of chemical reactions - correct answer -synthesis,
decomposition, single replacement, double replacement,
combustion
Synthesis chemical reactions - correct answer -always involves
a bond formula
A + B --> AB
, Page | 3
Decomposition chemical reaction - correct answer -when a
molecule is broken down into smaller molecules
AB --> A + B
Combustion reaction - correct answer -a chemical reaction that
occurs when a substance reacts with oxygen, releasing energy in
the form of heat and light
What is ph - correct answer -a measure of the hydrogen ion
concentration of a solution
How does the ph scale work? - correct answer -measures how
acidic or basic a substance is basic> 7, 7=neutral, acidic< 7
What are polymers - correct answer -Molecules made from a
large number of monomers joined together
