Elements have two names
What are pure substances?
This energy be reused
What is renewable?
A way to show chemical reaction with symbols and formula
What is a chemical equation and what does it show?
a subatomic particle determines the identity of an element.
what is Protons?
The different types of elements on the Periodic Table

Is Nitrogen oxide a compound?
A common nonrenewable energy source.
What is coal?
Reactants: H2 and O2 Product:H2O
In the equation H2+O2=H2O what are the reactants and what is the product?
this part of the atom contains most of its mass.
what is The nucleus? (protons and neutrons)
How elements are arranged on the periodic table
Are they arranged in order of increasing atomic number?
Air,Saltwater,Brass,Vinegar,and Coffee.
What are examples of Mixtures?
Can't be reused
What is nonrenewable?
To make sure the number on each element is the same on both sides.

Saltwater is not chemically bonded
What is a mixture?
Energy used the most.
Nonrenewable
The number of atoms of each element must be the same on both sides of the equation.
What does it to be balanced?
An atom that has gained or lost electrons.
What is ion?
Group that is known for being nonreactive, stable gases with full outer electron shells
What are Noble Gases/Group 18?
Compounds are chemically bonded while Mixtures are not
What is the difference between a Compound and a Mixture?
The percent of nonrenewable energy in a average American house.
75% to 80%
Matter can’t be created or destroyed in a chemical reaction so the total of number of atom must stay the same
Why is it important to follow the law of conservation of mass when writing chemical equations?
