This formula is used to determine how different your data is from the 'perfect' answer.
What is percent error?
This is communicated with shapes making direct contact with each other in a molecular diagram.
What are chemical bonds?
These properties can be 'measured' without changing the identity of the substance.
What are physical properties?
The smallest whole unit of matter

The two 'options' that describe everything in the universe.
What are matter and energy?
From the latin meaning 'same throughout', this type of substance can be referred to as a solution.
What is a homogenous mixture?
This vocabulary word refers to the repeatability of measurements.

These properties can only be 'measured' by fundamentally changing the matter being investigated.
What are chemical properties?
This can be referred to as a pure substance along with elements.
What is a compound?
These are signs of a chemical reaction.
You determined the density of a 1985 penny to be 8 g/mL, looking up the density of 1985 pennies you find the expected density of a 1985 penny is 7.2 g/mL. What is your % Error?
