Calculate H for the reaction of sulfur dioxide with oxygen. 2SO2(g) + O2(g) —> 2SO3(g)

(H SO2(g) = -296.8 kJ/mol; HSO3(g) = -395.7 kJ/mol)

a. -98.9 kJ
b. -197.8 kJ
c. 197.8 kJ
d. Not enough information is given.

and an explanation if possible please

Which statement is true about the part of the electromagnetic spectrum that human eyes can detect? it contains only the colors of the rainbow and television waves. o it is divided into seven ranges of wavelengths. it contains ultraviolet, visible, and infrared light. it is divided into nine ranges of wavelengths.

Indicate whether the specified alkyl halides will form primarily substitution products, only elimination products, both substitution and elimination products, or no products when they react with sodium methoxide. 1-bromobutane 1-bromo-2-methylpropane 2-bromobutane 2-bromo-2-methylpropane

Consider this equilibrium: n29) + o2(g) + 2no(c).nitrogen gas and oxygen gas react when placed in a closed container. as the reaction proceeds towards equilibrium, what happens to the rate of thereverse reaction?
