A Gas Evolution Equation is a molecular equation that involves the creation of specific gases. 

Gas Evolution Equations

Concept #1: Gas Evolution Equations

The gases of NH, CO, & SO2 are formed once median products lose a water molecule.  

Example #1: Predict whether a chemical reaction occurs and write the balanced molecular equation.

Practice: Predict the products formed from the following gas evolution equation.

CaS (aq) + HNO3 (aq) →

Practice: Predict the products formed from the following gas evolution equation.

NH4Cl (aq) + NaOH (aq) →

Practice: Predict the products formed from the following gas evolution equation

K2SO(aq) + H2SO4 (aq) →
