100分求一道物理题,
If aluminum (Al),with an atomic weight of 27,combines with oxygen (O),with an atomic weight 16,to form the compound aluminum oxide (Al2O3),how much oxygen would be required to react completely with 52g of aluminum
If aluminum (Al),with an atomic weight of 27,combines with oxygen (O),with an atomic weight 16,to form the compound aluminum oxide (Al2O3),how much oxygen would be required to react completely with 52g of aluminum
翻译：如果原子量为27的铝（Al ）与原子量为16的氧（O）结合,形成复合氧化铝（Al2O3 ）,将需要多少氧气与铝52克完全反应?4Al + 3O2¬ = 2Al2O34*27 3*2*16 2(27*2+16*3)108 96 20452g x所以：108/52=96/x,得x=46.22g所以需要的氧气质量为46.22克
