Determining Limiting Reactants

Students use a pressure sensor to experimentally determine the limiting and excess reactant when the amount of one reactant is varied; also, data is analyzed to reveal the coefficients in the balanced reaction.

Supports NGSS Performance Expectation HS-PS1-7: Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction.
