Complete the equations given below-1. Iron $ (\mathrm{Fe})+ $ Oxygen $ \left(\mathrm{O}_{2}\right)+ $ Water $ \left(\mathrm{H}_{2} \mathrm{O}\right) \rightarrow ? $2. Magnesium $ (\mathrm{Mg})+ $ Oxygen $ \left(\mathrm{O}_{2}\right){\prime} \rightarrow ? $
1.The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust.
Here is the word equation for the reaction:
Iron + Water + Oxygen → Hydrated iron(III) oxide.
Fe + H2O + O2 → Fe2O3·H2O
2. When magnesium is placed in a Bunsen burner flame in the air it burns with a bright, white flame. The product is a white powdery solid. This is happening because at high temperatures the magnesium atoms in the metal combine with the oxygen atoms in the air. A chemical reaction produces magnesium oxide, powdery ash.
The reaction is given by-
Magnesium + Oxygen → Magnesium Oxide
2Mg + O2 → 2MgO
