Question 2 of 10
Xelga [282]

The equation MgO + 2HCl → MgCl₂ + H₂O is  a balanced equation.

  • A balanced chemical equation contains equal number of atoms on both sides of the equation.
  • The equation is MgO + 2HCl → MgCl₂ + H₂O  which contains 1 atom of Mg, 2 atoms of chlorine, 2 atoms of chlorine, 1 atom of oxygen on both reactants and products sides.
  • So the equation is balanced.
  • An equation for a chemical reaction is said to be balanced if both the reactants and the products have the same number of atoms and total charge for each component of the reaction.
  • In other words, both sides of the reaction have equal amounts of mass and charge.
  • It follows law of conservation of mass.
  • Mass is neither created nor destroyed rather it can be transferred from one form to another.
