Yes. Zinc + HCl is an exothermic reaction, meaning it gives off heat as a result of reacting.
Zinc plus hydrochloric acid produces zinc chloride plus hydrogen gas. Zn +2HCl ---> ZnCl2 + H2
Increasing the temperature can increase the reaction rate between zinc and 6 M HCl. This is because higher temperatures provide more kinetic energy to the reactant molecules, increasing the frequency and energy of their collisions. This results in a faster reaction rate.
In the chemical equation Zn + HCl, zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl2) and hydrogen gas (H2).
2Zn(s) + 2HCL (aq) --> 2ZnCl + H2 (g) The reactants are zinc (Zn) and hydrochloric acid (HCl).
Evidence that a chemical reaction took place when zinc mixed with HCl includes the production of hydrogen gas bubbles, formation of zinc chloride as a product, and an increase in temperature of the reaction mixture due to the exothermic nature of the reaction. Additionally, the disappearance of the solid zinc as it undergoes dissolution is another indication that a chemical reaction has occurred.
The equation for the dissociation of hydrochloric acid (HCl) in water is: HCl + H2O -> H3O+ + Cl-. This shows the reaction where HCl breaks apart into a positively charged hydronium ion (H3O+) and a negatively charged chloride ion (Cl-).
Word Equation: Zinc + Hydrochloric Acid à Zinc Chloride + Hydrogen Chemical Equation: Zn + HCl à ZnCl2 + H2
When hydrochloric acid (HCl) is mixed with zinc, zinc chloride and hydrogen gas are formed. The reaction between HCl and zinc is a single replacement reaction where the zinc replaces the hydrogen in the acid to form zinc chloride and hydrogen gas.
According to the balanced chemical equation, the stoichiometry of the reaction is 1 mole of zinc reacts with 2 moles of hydrochloric acid. Therefore, to react with 2.3 moles of zinc, you would need 4.6 moles of hydrochloric acid (2.3 moles zinc * 2 moles HCl / 1 mole Zn).
The correct balanced chemical equation for the reaction between zinc (Zn) and hydrochloric acid (HCl) is: Zn + 2HCl → ZnCl2 + H2 This reaction produces zinc chloride (ZnCl2) and hydrogen gas (H2).
In the chemical reaction between solid zinc (Zn) and hydrochloric acid (HCl), zinc chloride (ZnCl2) and hydrogen gas (H2) are produced. The balanced chemical equation for this reaction is: Zn(s) + 2HCl(aq) → ZnCl2(s) + H2(g).
*first you set the equation: -(10mL of HCl)(1 mol of HCl)/(22.4 mL of HCl)= .446 mol of HCl *you divide by the volume of HCl which is 22.4 at STP. *Then you will divide that .446 mol of HCl with the mol of Zn, which is 1: -(.446 mol of HCl)( I mol of Zn)/(1 mol of HCl)= .446 mol Zn
