What is the missing coefficient in the balanced equation? What type of reaction is it? #Mg(OH)_2 + H_2SO_4 -> MgSO_4 + ?H_2O#
The stoichiometrically balanced equation is:
And this is an acid-base reaction.
Chemical equations are balanced with respect to mass and charge. For every reactant particle, there is a corresponding product particle. And for every reactant charge, there must be a corresponding product charge. When you come to study
And we cross multiply these individual redox reactions so that the electrons do not appear in the final redox equation:
Charge is balanced, and mass is balanced. As is ABSOLUTELY required.
In the given example, we could write the net ionic equation, i.e.
Are mass and charge conserved here?
