please help me with this chemistry problem.
1) Write out a balanced chemical reaction equation for the reaction of magnesium with hydrochloric acid,
What is the Theoretical Yield after balancing the chemical equation?
Metal + acid ---> metal salt + hydrogen gas
Mg + HCl --> MgCl2 + H2
If you place the correct coefficient in front of HCl, you will have the chemical equation balanced for Cl and H (which it is not now).
The balanced chemical equation assumes a theoretical yield of 100%. To calculate the actual yield we must know the amounts of reactants (Mg and HCl) actually used.
