Zinc reacts with silver nitrate to produce zinc … Iron can be coated with a thin layer of zinc in a process called galvanising.The zinc layer quickly reacts with oxygen to become zinc oxide. Learn to explain the factors that disrupt equilibrium, such as concentration, temperature, and pressure. So, it decomposes into carbon dioxide and water. When metals are burnt in air,they react with oxygen of air to form metal oxide. 2Zn + O 2 → 2ZnO ; Iron does not burn in air but iron filings when sprinkled in the flame burns vigorously. Given the limiting reactant, learn how to calculate the theoretical reaction yield, which is also known as the ideal reaction yield and percentage yield.
