Question

Balance the chemical equation $Mg+O_2\to MgO$

Answer 1

1. A balanced chemical equation is one in which all of the elements have an equal amount of atoms on both sides of the chemical equation. To follow the law of conservation of mass, chemical reactions must be balanced.
2. Balance the following chemical equation :

• However, in general, you should take the following steps:
  Count each atom type in the reactants and products.
  To increase the number of atoms or molecules in the substances, place coefficients in front of the symbols or formulas as needed.
  Steps 1 and 2 should be repeated until the equation is balanced.
• Balanced chemical equation: $2Mg+O_2\to 2MgO$
