The reaction of zinc metal and hydrochloric acid produces hydrogen gas and zinc chloride. Write the balanced chemical equation. Phases are optional Feedback In words, this reaction can be written as equation: Zn(s) + 2HCL(aq) -ZCI, (aq) + H, + In zinc + hydrochloric acid - hyd Next, determine the formula for each species. Hydrochloric acid has the formula HC. The symbol for sine can be determined from the periodic table Elemental hydrogen is diatomie. A zinc hon has a charge of +2 and a chloride Jon has a charge of -1. Determine in what ratio thescions must combine to form a neutral compound Be sure to balance the chemical equation
