Question

what happen when reation MG[s] + O2 + [g]

dont spam

Answer 1

Answer:

Mgo2 make ............ Ithink

Answer 2

$\bf{\odot \; UNBALANCED \; REACTION}$

$\sf \underset{Magnesium}{Mg\,(s)} \; + \; \underset{Oxygen}{O_2 \, (g)} \; \longrightarrow \; \underset{Magnesium \, Oxide}{MgO \, (s)}$

$\bf{\odot \; BALANCED \; REACTION}$

$\sf \underset{Magnesium}{2Mg\,(s)} \; + \; \underset{Oxygen}{O_2 \, (g)} \; \longrightarrow \; \underset{Magnesium \, Oxide}{2MgO \, (s)}$

• 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. The reaction is exothermic in nature as a large amount of heat is released. Magnesium burns with dazzling white light so wear eyeglasses while performing this reaction and also rub the magnesium ribbon with sandpaper.
