3) Determine the value of the enthalpy change, AHıxn, for the following reaction using the information below.
N2O(g) + NO2(g) → 3 NO(g)
2 NO(g) → N2(g) + O2(g)
2 N2O(g) → 2 N2(g) + O2(g)
NO(g) + 1/2O2(g) → NO2(g)
AH=-181 kJ/mol
AH=-163 kJ/mol
AH = -57 kJ/mol

Compare and contrast physical changes with chemical changes.

Nonpoint source pollution is difficult to control because it

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph
