here is the equation:Zn(s)+2HCl(aq)-->ZnCl2(aq)+H2(aq).If 20.0 moles of zinc react with excess hydrochloric acid. how many moles of zinc chloride are produced?....thxxx
Isn't it the same?
To find out how many moles of zinc chloride (ZnCl2) are produced when 20.0 moles of zinc (Zn) react with excess hydrochloric acid (HCl), we need to use the balanced chemical equation.
The balanced equation is:
Zn(s) + 2HCl(aq) → ZnCl2(aq) + H2(g)
From the balanced equation, we can see that for every 1 mole of zinc, 1 mole of zinc chloride is produced. Therefore, the number of moles of zinc chloride produced will be the same as the number of moles of zinc used.
In this case, we have 20.0 moles of zinc, so we can conclude that 20.0 moles of zinc chloride are produced.
