What ionic compound is formed when zinc reacts with hydrochloric acid?
Zn + HCl ---> ZnCl2 + H2 ZINC CHLORIDE IS THE ANSWER
What is the evidence that a chemical reaction took place when zinc mixed with HCl?
Yes, and zinc chloride and hydrogen are obtained.
What makes lithium chloride?
LiCl can be formed by mixing LiOH and HCl. The result is LiCl + H2O.
How many grams of zinc chloride can be formed from the reaction of 7.96 g of zinc with excess HCl?
The equation for the reaction is Zn + 2 HCl -> ZnCl2. The gram atomic masses of zinc and chlorine are 65.39 and 35.453 respectively. Therefore, the number of grams of zinc chloride that can be formed from 7.96 g of zinc is: 7.96{[65.39 + 2(35.453)]/65.39} or about 16.6 g of zinc chloride, to the justified number of significant digits.
What will be the pH of the solution formed by mixing 40ml of 0.1M HCl with 10ml of 0.45M NaOH?
pH=12.
What ionic compound is formed when zinc reacts with hydrochloric acid?
Zn + HCl ---> ZnCl2 + H2 ZINC CHLORIDE IS THE ANSWER
How is soudium chloride formed?
it is formed by mixing hydrochloric acid in sodium hydroxide. Naoh+Hcl=Nacl+H2o

Zinc granules are treated with dilute hydrocholoric?
When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.
What is formed when mixing HCl with silver?
Molecular equation = HCl(aq) + Ag (aq) =======> AgCl (s)
When zinc reacts with dil HCl what new compound is formed?
It forms hydrogen gas and Zinc chloride. but the reaction will be slow in dilute acid (when compared with that in concentrated acid).
What is the colour of zinc after when zinc granules react with hcl?
black
What reagent is reacted with zinc carbonate to form zinc chloride?
Hydrogen Chloride gas --> HCl or Hydrochloric Acid --> HCl(aq)
Will temperature increase in zinc plus Hcl?
Yes. Zinc + HCl is an exothermic reaction, meaning it gives off heat as a result of reacting.
