Let’s ex­am­ine the ex­am­ple of the in­ter­ac­tion be­tween zinc and hy­drochlo­ric acid. Zinc also re­acts with HCl, re­leas­ing small bub­bles of hy­dro­gen and form­ing zinc chlo­ride Zn­Cl₂. Zn + HCl → Zn­Cl₂ + H₂↑.

Zn + HCl = ZnCl2 + H2 is a Single Displacement (Substitution) reaction where one mole of solid Zinc [Zn] and two moles of aqueous Hydrogen Chloride [HCl] react to form one mole of aqueous Zinc Chloride [ZnCl 2] and one mole of Dihydrogen [H 2] gas

2025年1月6日 · The reaction between zinc and hydrochloric acid is a classical example of a displacement reaction where zinc displaces hydrogen from the acid. This process forms zinc chloride and bubbles of hydrogen gas, demonstrating the reaction mechanism clearly. The reaction is exothermic, releasing heat, which helps to drive the process.

The equation for this reaction is Zn + HCl -> Zinc + Hydrochloric Acid. During this reaction, zinc displaces hydrogen from hydrochloric acid to form zinc chloride and hydrogen gas. The reaction between zinc and hydrochloric acid can be explained by the activity series of metals.

This chemistry video tutorial explains how to predict the products of the single replacement reaction between Zinc and Hydrochloric Acid. It explains how to balance the molecular equation, how...

2023年3月21日 · The two elements, hydrochloric acid (Zinc) and (HCl), can react one and release hydrogen gas and zinc chloride. It is a single displacement process that’s exothermic and generates huge amounts of heat.

Consider the reaction between Zn and dilute hydrochloric acid forming zinc chloride and liberating hydrogen. Write the balanced chemical equation for the following and identify the type of reaction in each case. Zinc reacts with hydrochloric acid to give chlorine gas.

Zn + HCl = ZnCl 2 + H 2 How to Balance Zn + HCl = ZnCl2 + H2 Solubility Equation Determine the state or phase of each substance (gas=g, liquid=l, solid/non-soluble=s, aqueous/soluble=aq) in its undissociated form by using the solubility rules or a solubility table. Zn (s) + 2 HCl (aq) = ZnCl 2 (aq) + H 2 (g)

Zn is balanced: 1 atom in reagents and 1 atom in products. H is not balanced: 1 atom in reagents and 2 atoms in products. Cl is balanced: 2 atoms in reagents and 2 atoms in products. Let's balance this equation using the algebraic method. First, we set all coefficients to variables a, b, c, …

The reaction between zinc metal and the hydrochloric acid solution is an example of a single displacement reaction. Zinc reacts with dilute hydrochloric acid to give zinc chloride and hydrogen gas. The hydrogen gas is seen in the form of effervescence (bubbles) in the test tube when zinc granules are added to dilute hydrochloric acid.
