WHAT IS the replacement of HCl and zinc metal?
Zinc plus hydrochloric acid produces zinc chloride plus hydrogen gas. Zn +2HCl ---> ZnCl2 + H2
What is the effect of temperature on the reaction of zinc with 6 M HCl?
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 plus HCL?
In the chemical equation Zn + HCl, zinc (Zn) reacts with hydrochloric acid (HCl) to produce zinc chloride (ZnCl2) and hydrogen gas (H2).
What are the reactants to Zn plus HCl equals Zn plus H2?
2Zn(s) + 2HCL (aq) --> 2ZnCl + H2 (g) The reactants are zinc (Zn) and hydrochloric acid (HCl).
What is the evidence that a chemical reaction took place when zinc mixed with 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.
What is the equation for the dissociation of hydrochloric acid?
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-).
What is a word equation for zinc reacting with hydrochloric acid?
Word Equation: Zinc + Hydrochloric Acid à Zinc Chloride + Hydrogen Chemical Equation: Zn + HCl à ZnCl2 + H2
What is formed when mixing HCl with zinc?
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.
How many moles of hcl are needed to react with 2.3 moles of zinc the products of the reaction are zinc chloride and hydrogen gas 1 Zn plus 2 HCl -- 1 ZnCl2 plus 1 H2?
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).
Zn plus HCl equals ZnCl plus H is not correct?
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).
What elements are in this chemical reaction Zn s plus HCl ZnCl2 s plus 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).
.25 g of zinc reacted with 10 mL of HCl what is the moles of zinc reacted?
*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
