How much quantityof zinc will have to be reacted with excess of dilute HCl solution ti produce sufficient hydrogen gas for completely reacting with the oxygen obtained by decomposing 5.104g of potassium chlorate?

How much quantityof zinc will have to be reacted with excess of dilute

1.	How much quantityof zinc will have to be reacted with excess of dilute HCl solution ti produce sufficient hydrogen gas for completely reacting with the oxygen obtained by decomposing 5.104g of potassium chlorate?
Answer» Solution : `1.0` mole of `KClO_(3) -= 3.0` mole of `Zn` `(5.104)/(122.5)` mole `KClO_(3)=(3xx5.104)/(122.5)` MOL of `Zn = (3xx5.104xx65)/(122.5)=8.124 ""G"" Zn`
