Answer : Ice at 0° C.

Explanation : The statement that most of the substances becomes less dense as the temperature increases is not true for ice.

As when the temperature increases the ice melts into liquid which is found to be more denser than ice. The mass is observed to be the same, but the volume decreases as the melting process occurs.

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. ^^
