CO2 + H2
What are the chemicals of the left side of the arrow called?
Reactants
Why does the concentrations shift away from the substance?
Extra concentration must be used up
What happens in a weak acid?
Partially breaks apart
What is molarity?
amount of solute/volume of solution
What is the importance of balancing equations
Because Ms Maher told us to
What happens when there is to much of a chemical?
It becomes a limiting factor
What is the La Chatelier Principle?
When something is done to a reaction, the reaction will respond in the opposite way.
In the antacid lab, why was Alka seltzer the strongest?
It caused the most change in the pH of the solution.
what does AAM stand for and where is it used in solving for molarity?
Average atomic mass
Used to solve for g/mol
