A sample of CaSO4(s) is placed in a container and then heated so that it decomposes according to the following equation: 2 CaSO4(s) ==> 2 CaO(s) + 2 SO2(g) + 02(g)
We discussed several different types of hydrocarbons in this lesson. Which one is saturated?
Given the data: N2 (g) + O2 (g) → 2 NO(g) H = +180.7 kJ 2NO(g) + O2(g) → 2NO2(g) H = -113.1 kJ 2N2O(g) → 2N2 (g) + O2(g) H = -163.2 kJ Use Hess's law to calculate
