Warm-up problems used to start my AP Chemistry class. Most of these warm-ups will focus on content already covered in the course, or in prior courses, in an effort to reduce the need for review prior to the AP Test.

AP Chemistry Warm-up for April 10

Review Problem

Calculate ΔH for the first reaction using the thermochemical information from the other three reactions.

ZnO + CO2 → ZnCO3                 ΔH = ?

H2CO3 → H2O + CO2             ΔH =  62 kJ

Zn(OH)2 → ZnO + H2O                 ΔH =  72 kJ

Zn(OH)2 + H2CO3 → 2H2O + ZnCO3                      ΔH =  117 kJ
