红磷加氧点燃会生成 ‘五氧化二磷’
这个化合物中,一个分子由5个氧原子和2个磷原子组成 物质守衡,反应消耗了氧,当然产物中也会有氧原素咯!
1.别名：(偏)磷酸酐
2.分子式：P4O10(一般写作P2O5）
3.分子量：141.94
4.危规分类及编号：GB8.1类81063.
原铁规：一级无机酸性腐蚀物品,91034,UN NO.：1807.
IMDG CODE 8198页,8类.
5.化学式：P2O5
6.制作方法
五氧化二磷
磷+氧气---(点燃)--五氧化二磷
4P+5O₂==2P2O5
3氧化二磷
还是五氧化二磷 ，只不过化学式不同于一般的P ，红磷是P4 白磷是P
P4+5O2===2P2O5(条件点燃）
