During volcanic eruptions, hydrogen sulfide gas is given off and oxidized by air according to the following chemical equation:
         2H2S(g) + 3O2(g) → 2SO2(g) + 2H2O(g)
         Calculate the standard enthalpy change for the above reaction given:
3S(s) + 2H2O(g) → 2H2S(g) + SO2(g)
ΔH° = 146.9 kJ/mol
S(s) + O2(g) → SO2(g)
ΔH° = –296.4 kJ/mol
 

◦ –1036.1 kJ/mol
◦ –742.3 kJ/mol
◦ –149.5 kJ/mol
◦ 443.3 kJ/mol
◦ 742.3 kJ/mol

Although the Roman numeral for the number 4 has always been taught to have been "IV," according to historians, the ancient Romans probably used "IIII" most of the time. This is partially backed up by the fact that early grandfather clocks displayed IIII for the number 4 instead of IV. Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
