Objectives: Review of gas-mass stoichiometry
Announcements: All parts of this project
are due tomorrow
Warm-ups: 6.5 L of N2 gas is generated
(@STP) in the reaction of K3N with Cl2.
Write the balanced equation for the
reaction & determine what mass of K3N
& Cl2 are needed to produce that amount
of nitrogen gas.
Need help with parts of the rocket project?
