What is an anion?
An ion that is formed when electrons are gained, giving it a negative charge.
100

What type of bond is in a molecular compound?

Covalent/Molecular

100

What are the products of combustion? 

Water and CO2

100
What does the Law of Conservation of Mass have to do with balancing equations?
Matter can be neither created nor destroyed. This means that the number of atoms of each element on either side of the equation must be the same, they are simply rearranged.
100
What is an acid?
A compound that releases H+ in solution.
200

What component of the atom moves in order for an ion to form?

Electron

200
What are the types of elements in a molecular compound? ______ + _______ ?
Non-metal + Non-metal
200

The ping pong ball shooting is an example of what type of reaction?

Combustion 

200

What does the acronym HOFBrINCl mean?

Those atoms are diatomic

200
Do bases have a high or low pH?
High.
300

Why do elements accept and give away electrons?

To have a full valence shell.

300

What prefix is used to name an element with 4 atoms?

Tetra

300
What type of reaction is one where two compounds exchange element partners to form two new compounds?
Double Displacement
300
Is this equation balanced? 2H3PO4 + 6KOH --> 2K3PO4 + 6H2O
Yes.
300
What does pH measure?
The amount of H+ in a solution. The lower the pH the more H+ in a solution.
400
How is an ionic bond formed?
Electrons are lost from one atom and gained by the another.
400
True or False? When the first element in the formula has one atom, mono- is used.
False
400
What type of reaction is Cu + AgNO3→ Ag + Cu(NO3)2?
Single Displacement
400
What is a balanced equation?
An equation with the same number of atoms of each element on either side of the arrow.
400
Would a solution with a pH of 1 be a strong acid, weak acid, strong base or weak base?
Strong acid
500
Looking at an oxygen, will it lose or gain electrons, what will its charge be?
It will gain two electrons and have charge of 2-.
500
What is the name for N2O4?
Dinitrogen tetroxide
