CE 96 Chem Q 7(a)(iii)(4) 問題
條題目就兩種 atoms:
H hydrogen (atomic no. : 1 ,, mass no. : 1)
D deuterium (atomic no. : 1 ,, mass no. : 2)
佢就話
Deuterium reacts with O2 in the same way as Hydrogen
2D2 + O2 --> D2O
The product of the reaction is known as "heavy water"
跟住佢叫你揾 formula mass of water
個ans 就係 2+2+16=20
我想問嘅係點解會知道 relative atomic mass of D 係 2 ?
佢只係俾左 mass no. 嘅資料你 ((更何況mass no. = relative isotopic mass,,而且仲係isotope))
所以,, 我想知點解可以推斷到係 2 ??
many thanks~
