A. Use Hess's law and the following equations to calculate ΔH for the reaction SO2(g) + NO2(g) SO3(g) + NO(g). (Show your work.) (8 points)
i. SO3(g) SO2(g) + O2(g)
ΔH = –98.4 kJ/mol
ii. 1/2 N2(g) + 1/2 O2(g) NO(g)
ΔH = 90.3 kJ/mol
iii. NO2(g) 1/2 N2(g) + O2(g)
ΔH = –33.1 kJ/mol
B. If a radar speed gun operates at a frequency of 3 × 1010 Hz (30 GHz), what wavelength of electromagnetic radiation does it use? What kind of electromagnetic wave does the radar gun use?
THANK YOU
Please no fake answers i worked really hard for these points and they will be reported
