Calculate ΔH for the following reaction: N2 + 3H2 → 2NH3. Average Bond Energies N≡N, 941 kJ/mol H–H, 432 kJ/mol N–H, 391 kJ/mol HOW DO WE GET THERE? What is the total energy required to break the reactant bonds (in both N2 and H2)? Total energy required = kJ

The organism shown is a free-living one that is anchored to the bottom of ponds and streams during one stage of its life cycle what is the common name for the group to which this organism belong

What is the effect of returning nuclear reactor cooling water back into bodies of water?

28. which is not a reason that water is used to store spent fuel rods from nuclear power plants? water increases the speed of the chain reaction in the fuel rods. water protects nuclear power plant workers from the high temperature and radiation of the fuel rods. water acts as a radiation shield to reduce the radiation levels. water cools the spent rods. salts action
