The space shuttles expendable booster engines derive their power from solid reactants: FM 117.49 (a) Find the oxidation numbers of the elements N, Cl, and Al in reactants and products. Which reactants act as reducing agents and which act as oxidants? (b) The heat of reaction is 9 334 kJ for every 10 mol of Al consumed. Express this as heat released per gram of total reactants.
8-17-16 Chpt. 1 Reviewing basic concepts from General chemistry. Sec 1.2 Atomic Structure -Atoms H O S All have different Lewis Dot structures. Different e orbitals have different Energies S, Px, Py, z (P orbitals are of the same energy) -Atomic # = # of protons -H 2O 4toms bond together to create molecules -Atomic mass= protons+ neutrons -Neutrons can vary within the same element creating Isotopes C C C13 14 -Valence shell electrons are involved in bonding Sec 1.3 Molecules and Bonding -Ionic bondi
