Reson : the reflecting surface of spher You can specify conditions of storing and accessing cookies in your browser, Goodmorning. What date do new members of congress take office? Then during dry cycles, carbon dioxide reacts with the zinc hydroxide and converts to a thin, compact, and tightly adherent layer of zinc carbonate. b) On treatment with hydrofloric acid, silicon dioxide forms silicon tetrafluoride and water. Zinc is a chemical element with the symbol Zn and atomic number 30. A zinc chloride solution (ZnCl2) is prepared by reacting zinc carbonate with dilute hydrochloric acid, write the balanced equation for this reaction ZnCO3 + 2HCl --> ZnCl2 + H2O + CO2 Student must be aware of the formula for a carbonate (CO3) and how to balance the equation.
