The enthalpy change for the explosion of ammonium nitrate with fuel oil is –7198.00 kJ for 3 moles of NH4NO3. If ΔHrxn for the thermal decomposition of 2 moles of TNT is –20,306.00 kJ, how much TNT is needed to equal the explosive power of 1 mole of ammonium nitrate?

Can someone me with questions 12 and 13 plz.

Which statement is usually true about the relationship between activation energy and reaction rates? low activation energy barriers result in low rates. high activation energy barriers result in low rates. low activation energy barriers result in no reaction. high activation energy barriers result in no reaction.

Joe shines white light into a bowl half full of water at an angle of incident of 27.5°. calculate the angle of refraction in the water given the indices of refraction for air and water are 1.00 and 1.36, respectively.
