Mg + O2---------> MgO

Make sure to include the following details in your answer in complete sentences:

- Is the chemical reaction balanced?

- Is it following the law of conservation of mass, why is not following?

- What can you do to make sure that the equation becomes balanced and follow the law?

Answers

Answer 1

Answer:

- The chemical reaction is not balanced. There is two oxygens on the reactant's side while there's only one oxygen on the products side.

- I would not say it's following the law of conservation of mass as it's not a balanced equation.

- To balance this equation, you would need to add the coefficient of '2' to Magnesium (Mg) on the reactants side, and add the coefficient of '2' to the products side.  This would make it so that there's 2 Mg's and 2 O's on both the reactant's side and products side.

edit: I hope this helped you in some way. ^^
