How do you write the word equation and balanced symbol equation for a lithium reacting with water and zinc reacting with dilute hydrochloric acid?

Answer 1

Ellie Andrews

#"Lithium + water "rarr" Lithium hydroxide + dihydrogen gas"#

#"Zinc + hydrochloric acid "rarr" Zinc chloride + dihydrogen gas"#

#Li(s) + H_2O(l) rarr LiOH(aq) + 1/2H_2(g)#

#Zn(s) + 2HCl(aq) rarr ZnCl_2(aq) + H_2(g)#

Word equation for the reaction of lithium with water is: Lithium + Water → Lithium hydroxide + Hydrogen; balanced symbol equation for the reaction of zinc with dilute hydrochloric acid is: Zn + Hydrochloric acid → Zinc chloride + Hydrogen; balanced symbol equation for the reaction of zinc with water is: Zn + 2HCl → ZnCl2 + H2.
