HELP ME PLEASE ASAP IVE POSTED THIS LIKE THREE TIMES AND NO ONES RESPONDED PLEASE 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

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

they are all solids.

it is reliable if two scientists recorded it
