Heat causes a fusion of zinc and copper to form brass (gold-colored). Brass is 60-82% Cu and 18-40% Zn. To Conduct Demonstration Heat NaOH/Zn mixture to near boiling in a crucible (3.5 in in diameter ...

relative atomic mass of Zn = 65.4 relative formula mass of HCl = 1.0 + 35.5 = 36.5 total relative formula mass of reactants = 65.4 + (2 × 36.5) = 138.4 total relative formula mass of desired ...
