Write one observation when Magnesium ribbon is burnt in air |
|
Answer» 2Mg + O2 = 2MgO He is asking for observation. When mg ribbon burns in air White dazzling flame come out of it and a white powdery substance will be formed. When the magnesium ribbon is burnt in air it forms a white powder called magnesium oxide. It is obtained by the reaction of oxygen and magnesium. 2Mg + O2 = 2MgO Magnesium ribbon is burnt in air which is oxygen with a white dazzling flame... Then after occurring with oxygen it convert into magnesium oxide which is a white powdery substance....Mg2 + O2 = 2MgO When magnesium ribbon is burnt in air, it combines with oxygen to form white powder magnesium oxide MgO with the release of heat and light.\xa0It\xa0forms\xa0a white powder of the\xa0magnesium oxide.\xa0Magnesium\xa0gives up two electrons to oxygen atoms to\xa0form\xa0this powdery product.2Mg+O2\u200b⟶2MgO |
