<p>First of all Thank You for your time :slight_smile:
so,
In 2011 AP Chem FR,there is this equation whose logic in the balancing part I ain’t understanding.
Ques)-Solid magnesium hydroxide is added to a solution of hydrobromic acid.</p>

<p>CB answer =Mg(OH)2 + 2H+ –> Mg2+ + 2H2</p>

This thing is troubling me in almost all balancing equation questions!!!
Help appreciated</p>
