我没学过已烷庚烷这部分不知道怎么解!
Hexane reacts with oxygen according to the equation shown below.If 35.7g of heptane react,how many grams of carbon dioxide will be produced?
__C6H14 + __O2 = __H2O + __CO2 (NOT BALANCED)
翻译过来大概是这样：
已烷和氧气如下列方程式反应.如果35.7克的庚烷反应了,那么有多少克的二氧化碳会生成?
__C6H14 + __O2 = __H2O + __CO2 (需要先配平)

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 + (n+1)H2O
题里所给的是含六碳的己烷，不是七碳的庚烷。
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
2*86.20 12*44.01
35.7 X X=35.7*12*44.01/2/86.2=109.36 g
如果不先配平是算不出来的。
