a(2) the polarity of the molecules, the bigger the intermolecular forces.[translate] aCompare the magnitude of intermolecular forces of H2O and O2:[translate]
a(4)Many factors influence van Edward force: molecular size, spatial configuration of molecules, molecular charge distribution. [translate] aH2O is polar molecule ,and O2 is non-polar molecule. [translate] aTherefore ,H2O is larger than O2 in the magnitude of intermolecular forces. [translate] ...
先用烷类燃烧通式确定系数2 C6H14 + 19 O2 = 14 H2O +12 CO2 庚烷的就是 C7H16 + 11 O2 = 8 H2O + 7 CO2 设生成CO2 x g然后列式找关系,100/35.7=44/x x=15.708g 解完了烷类燃烧通式:CnH2n+1 + (3n+1)/2 O2 = nCO2 +... 解析看不懂?免费查看同类题视频解析查看解答 更多答案(...
