Question

Give the balanced chemical equation for the reaction in which; Magnesium($\mathrm{Mg}$) forms magnesium oxide ($\mathrm{MgO}$) when burnt in oxygen(${\mathrm{O}}_2$).

Answer 1

Answer

Note: Steps used for finding balanced chemical equation

• Count each type of atom in reactants and products.
• Place coefficients as needed, in front of the symbol or formula to increase the number of atoms or molecules of substances
• repeat steps 1 and step 2 until the equation is balanced.

So the balanced chemical equation for the above reaction is given by;

$2\mathrm{Mg}\left(\mathrm{s}\right)+{\mathrm{O}}_2\left(\mathrm{g}\right)\stackrel{}{\to 2\mathrm{MgO}\left(\mathrm{s}\right)}$
