Greenhouse gases
Certain gases in Earths atmosphere affect the balance between incoming sunlight because they Trap heat.
Greenhouse gases
allow sunlight in the atmosphere to warm earth but prevent heat from escaping.
Earths most significant greenhouse gas
Global Warming
Increase in earths average temperature
The numerical relationship between chemical quantities in a balances chemical equation
Limiting Reactant
The reactant that is completely consumed in a chemical reaction.
Theoretical Yield
The amount of product that can be made in a chemical reaction based on the amount of limiting reactant
Actual Yield
Amount of Product actually produced by a chemical reaction
Percent Yield
Actual Yield/ Theoretical Yield x 100
Elemental Oxygen
