CHEM 161 EXAM 2 Answers actual yield the experimental quantity, in grams, of product obtained in a reaction. Avogadro’s number the number of particles (6.022 x 10^23) of a substance in 1 mol of that substance. By definition, Avogadro’s number is equal to the number of carbon-12 atoms in exactly 12.00 g of carbon-12. balanced appropriate coefficients have been added such that the number of atoms of each element are the same in both reactants and products. chemical equation a prec...

Lattice energy - - The enthalpy change when 1 mole of ionic compound is formed from its gaseous ions under standard conditions - It is the energy given out when ions of opposite charges comes together to form an ionic lattice Lattice energy is endothermic or exothermic? - - It is always exothermic because bonds are being formed (ionic bond) between oppositely charged ions, not broken Equation showing the formation of NaCl lattice - - Na^+(g) + Cl^-(g) > NaCl(s) The state of the opposite...
