Document Summary
Can be proofed in many ways: as long as the theoretical yield and percentage yield is an exact match in your equation, different number means incorrect answer. Find the limiting reactant: identify the molarity of each reagent. Note: convert ml to l in your measurements. Mol: volume (l) x molarity: use balanced reaction to determine limiting. % yield = (actual yield/theoretical yield) x 100 = (64. 6/88. 0) x 100: 73. 4% The atom: mass and volume, comes from particles within atom (protons [p+] and neutrons [n] from within the nucleus, electrons [e-] outside the nucleus. Proposed by john dalton"s atomic theory: e. g. Ions = different numbers of electrons: cations, anions. Attract, contact, interact and combine with each other: intermolecular forces between positive nuclei and negative electrons, chemical bonding between e- and p, transferring or sharing e, delocalizing electrons. Thermal or heat: not the same as temperature, directly proportional (positively correlated) Ekinetic= 0. 5(mv)2 used for particles: m=mass(kg, v=speed in ms-1.
